Custom Motorcycle Seats Designed For Your Comfort
When a motorcycle seat doesn't fit right, it can ruin your day. What looked and felt good in the showroom can turn into a torture device an hour into your Sunday ride.
Every Japanese street bike, chopper, sport bike, dirt bike, Harley, enduro, streetfighter and scrambler has its own distinctive look and feel. One thing they have in common: the original seat rarely fits the rider. They rarely fit, because OEM motorcycle seats are never manufactured for you. They're made to fit an "average" body.
The solution? A custom-fitted seat and high performance motorcycle upholstery from Mac's Upholstery.
Motorcycle Seat Recovering
We sculpt and recover motorcycle seats to fit individuals. We lower, narrow or widen seats so everything feels just right. We fabricate and install special polymer gel seat pads to maximize your comfort.
In addition to motorcycle upholstery, we also custom-fit seats and gel pads for ATVs, scooters, trikes, bicycles, race cars, riding mowers, trucks, cars, snowmobiles, helm seats, go-karts, wheelchairs, fork lifts, furniture, equestrians, mattresses, floors and personal seats for sporting events.
Rebuild Yamaha RD350 Seat
Most motorcycle aficionados consider the Yamaha RD350 one of the great bikes of the 1970s. It's an air cooled two stroke cafe racer capable of leaving more powerful bikes in the dust; perfect for zipping around town.
Yamaha manufactured the RD350 from 1973 to 1975. Since all these bikes are more than forty years old, seat repair/rebuild is pretty common. One owner took the unusual step of roughing-out the shape he wanted using home insulation foam.

The seat pan was in good shape, so we left it alone. Using the customer's foam template, we rebuilt the foam and crafted a new seat cover using the finest marine grade black vinyl. As you can see, the white welting complements the trim.
If this had been a touring bike we would've recommended a custom gel pad insert to smooth the ride. Since the RD350 is designed for quick trips around town, a gel pad wasn't necessary. The rebuild was perfect; the seat fit like a glove.
Customize Suzuki Seat
Why wait until your seat is old and tattered before having it shaped to fit your frame?
Before hitting the road, the owner of a brand new Suzuki TU250X called us to custom shape his seat so the ride was perfect from day one. You can see what the original seat looked like in the first two pics below.
The owner wanted something stylish with a little more beef.
Before Custom Shaping
After Custom Shaping
We began by removing the old seat cover and adding a layer of rebond foam. Rebond is firmer than standard polyurethane foam. Using this sort of material accomplished two objectives; it raised the seat by an inch and gave it a slightly stiffer feel. Because he lives in Alaska, he requested we use a superior quality marine vinyl engineered to remain supple in extremely cold temperatures. We fabricated the seat cover from the highest quality vinyl; the same stuff we use for the Alaska fishing fleet.
Finally, the owner wondered if off white diamond stitching might be a nice tough. As a matter of fact, yes!
Repair Cracked Seat Pan
When twin cracks sprout on either side of an old motorcycle seat pan you figure it's time to shop for a new seat. In most cases you'd be right. But, if you're determined to keep the bike original or if it's hard to hunt down a replacement seat, give us a call.

Both Sides Cracked
Fixing this seat pan was a little more involved than a typical restoration. In this instance, we had to remove all the nasty polyurethane residue, hammer the bent metal edges back into shape, then prep the surface for welding.
After welding the cracks, we treated the rust, covered the seat pan with a fresh coat of paint and cut new seat foam. Finally, we installed a standard replacement cover with new straps and chrome. Good as new.
Repair Honda XL Motorcycle Seat
Honda manufactured the XL dual-sport series from 1972 through the 80s. If you're above a certain age, you know this bike as a four-stroke enduro. Since the last one was built when Ronald Reagan was President you'd be hard-pressed to find an original XL seat in good condition. A lot of them look like the first row of pics below.

Unless the seat pan is rusted or cracked this sort of restoration is pretty straightforward. Whenever possible we try to salvage the old foam. In this instance, the polyurethane foam was too far gone. We replaced the foam, then built a new seat cover; good as new.
Motorcycle Seats Sold Online
Buying stuff on the Internet can be an adventure. It's nearly impossible to get a feel for a product when all you have to go on is a snapshot or two.
Here's a great example of something that failed to meet expectations. This mass produced seat and cover looked great online. But, when it arrived there were wrinkles in the vinyl cover (below left). The cover was wrinkled because the seat foam had collapsed.
Wrinkled Seat Cover
Instead of sending back the seat and rolling the dice on a replacement, the bike owner called us.
He wondered if we could cut the seat cover to fit the foam. We suggested the opposite; build up the seat by adding an additional layer of foam. Actually, it's a little more complicated than that. The old and new foam have to be paired, prepped, glued together, and then reshaped. As you can see (above right), the repaired seat turned out smooth as a baby's butt.
Damaged Foam & Wrong Cover
The craftsmen at Mac's Upholstery specialize in custom motorcycle seats and gel pads, but every now and then a biker drops by with a simpler request. They want us to install a stock cover on their old seat. We're happy to do that, but there are a couple of things to keep in mind before calling.
Damaged Seat Foam
Wrong Size Seat Cover
First, if your seat cover is worn or damaged the foam inside may be shot. Some manufacturers cut corners by using cheap seat foam. You don't want to put a brand new cover on damaged foam. If you need a new cover, you may need new foam.
Also, be careful if you purchase a new seat cover online. A customer recently bought one on the web. He got the cover he ordered (above right), but it was the wrong size. The cover he purchased didn't fit, so we couldn't use it. If he'd ordered from us, that wouldn't have happened.
The Finest Craftsmanship
When it comes to motorcycle seats, our reputation precedes us — in a good way.
Bike owners from as far away as Washington DC send us seats for foam repair, shaping, upholstery work and custom gel pads. Just recently, a biker from Glendale, California sent us a badly damaged motorcycle seat from a Honda Scrambler 305 with instructions and schematics. This was a restoration project; he wanted the seat to look just like it did in the showroom back in the 1960s.
Honda Scrambler 305

As you can see from the pre-restoration pic below, there wasn't much left of the original motorcycle seat. Instead of a gel pad to soften the ride, somebody way back when had strapped chunks of blue foam under the old cover. Holes from the diamond tufting had turned the seat foam into swiss cheese. In short, the old seat was trashed.
Seat Before Restoration
Honda Seat After Restoration
We began the restoration by stripping the seat. As you might expect on a bike this old, we discovered lots of rust on the seat pan. After treating the rust and repainting the seat pan, we cut brand new foam and installed a state-of-the-art custom gel pad. We used durable, marine-grade vinyl for the new seat cover. Finally, we dressed-up the seat with precision diamond stitching, a matching welt and a passenger grab strap.
When it went back to California the restored Scrambler seat was even better than the original. You don't have to live in Seattle to get the best motorcycle seats. Just drop a dime and pop your seat in the mail. We'll do the rest.
Keep Your Passengers Happy
Harley Davidson's Fat Bob® is a great bike, but there's one problem. Every Bob rolls off the assembly line in Kansas City with a passenger perch the size of a postage stamp. There's even a written guaranteed pinned to every seat — your passenger's butt and legs are guaranteed go numb ten miles into your ride or double your money back.
Okay, the part about the guarantee isn't true, but as you can see in the "before seat rebuild" pic below, the passenger perch is way too small for anything more demanding than a trip to Freddy's.
Harley Davidson Passenger Perch
Redesigned Passenger Perch
Passenger Perch After Rebuild
The solution is simple — rebuild the passenger perch wider and taller.
Seat foam comes in a range of densities. Standard foam isn't sturdy enough to provide the necessary support for this sort of rebuild. In this instance, we need a stiff, higher density foam. Unfortunately, stiff foam is usually too stiff for comfort. To soften the seat we use the higher density stuff for the base, then cover it with a soft, lower density foam. The double layer provides the necessary support without sacrificing comfort.
With the seat rebuilt, this Fat Bob® is ready for the road.
Leather Or Vinyl?
If this 30 year old Harley-Davidson Shovelhead looks brand new, it's because the owner has spent years restoring it. With the mechanical work complete, it was time for a new seat. The question we always ask the bike owner at this point — vinyl or leather?
Before New Seat
Before New Seat
Today's premier vinyls are almost indistinguishable from standard leather. Even so, there's nothing quite like the look and feel of leather. Leather can also be more durable than petroleum-based vinyl, if properly maintained. On the other hand, leather is usually more expensive. And leather can go bad if it gets soaked; you don't want to ride in the rain with a leather seat. Since it does have a tendency to rain in the Pacific Northwest, we usually recommend vinyl.

Leather Motorcycle Seat
Custom Harley Seat
The owner of this vintage bike wanted to go first cabin and cover the seat in leather. In this case, we figured it was okay. This is not an everyday motorcycle; it's the sort of bike you park in the garage and only ride when it's nice outside.
As you can see, the brand new leather seat turned out great. With the seat installed, this Shovelhead is ready for the road.
A Clever Idea
Hunting down a replacement seat for a vintage motorcycle can turn into a wild goose chase. When one of our customers came up empty-handed in his quest for a Honda Twin Star seat, he called us. We offered to fabricate a custom seat from scratch, but the biker had an offbeat idea. Instead of spending hundreds on a brand new steel and fiberglass seat frame, he suggested building the seat on an inexpensive skateboard deck.
We scratched our heads for a few minutes, then gave it a go.
Seat Built From Skateboard
Mounting Plate Holes
After confirming the skateboard fit the motorcycle seat plate, the bike owner yanked the skateboard's wheels and drilled mounting holes in its deck. With the board prepped, we went to work.
The owner preferred a low profile seat, so we kept it simple and minimized the foam depth. We used a durable marine-grade vinyl for the cover. The lateral dorsal pleats are stylish, but they also serve a purpose; a pleated seat cover is 'tackier' than a seat with a plain surface. Finally, we turned the flared end of the old skateboard around to allow plenty of space for the tail light.
Turned out that building a motorcycle seat on a skateboard deck was not as crazy as it sounded.
Vespa Scooter Seat
Most of our seat covers are fabricated for motorcycles and the occasional watercraft, but we do plenty of scooters, especially when the weather turns nice.
Scooters are becoming more and more popular in Seattle; they're convenient, easy to park and inexpensive to operate.
While it's hard to improve upon the classic look of an Italian Vespa, some owners take the opportunity to personalize their Vespa with a custom made seat cover.
Here'a a great example of how something as simple and inexpensive as diamond stitching can transform a plain vinyl seat into something stylish and unique.
King & Queen Chopper Seat
When a do-it-youselfer hits a dead end, their project occasionally ends up in our shop. Sometimes the work they've done is so sketchy we have to start from scratch, other times we're able to salvage the project. In this case, a bike owner built the base for a chopper seat, but didn't have the tools or experience to finish it.
Homemade Seat Mold
King & Queen Chopper Seat
As you can see from the first two pics, the homemade fiberglass base is pretty ragged. Before doing anything else, we had to determine if it was worth saving. Fortunately, it was sturdy. And the shape was only a little bit off. It took hours of smoothing and adjusting, but in the end were able to transform this hunk of fiberglass into an acceptable seat frame.
With the base finished, we laid down a layer of rebond foam, tweaked the padding here and there, then went to work on the cover. The bike owner selected a tough, marine grade black vinyl with a matte finish. Classic welting and a traditional tuck & roll finish were perfect for this shape. When finished, you'd never know this king and queen chopper seat began as misshapen fiberglass.
Repair Motorcycle Seat
You're probably gonna think we doctored these snapshots. It's true, we did Photoshop a carpenter’s square over two of them, but only to prove a point. In some places this thing (first two pics) could pass for abstract art, but nobody'd ever mistake it for a superbly crafted motorcycle seat cover. One of our competitors built it. What's worse, they charged the customer for the lousy work.
Motorcycle Seat Or Modern Art?
Out Of Alignment
Our job was to fix the other guy's mistake. The seat face was still in pretty good shape, so we salvaged what we could. Unfortunately, the sides were too badly botched to reuse. Instead of reprising the waffle stitch design, the owner wanted to try something different — wrapping the sides and rear in plain tan leather.
Fitting New Cover
That's More Like It!
As you can see, the seat repair turned out great. But, the bike owner learned an expensive lesson: if you want something done the right way, bring it to Mac's.
A Smooth Ride With Custom Motorcycle Seat Gel Pads
We discourage bikers from buying off-the-shelf gel pads such as Butt Buffers. In our opinion, these one-size-fits-all gel pads for motorcycles are a waste of money. They're not designed for your body or your bike. They may slightly improve your ride, but they don't begin to match the comfort of our custom-fit motorcycle seat gel pads.
Our custom-designed motorcycle gel pads & cushions are fabricated from sheets of a special polymer created for the medical field. This ultra-soft, shock absorbing material was invented more than 30 years ago to prevent pressure sores in patients confined to a bed or wheelchair.
Gel Seat Pads & Gel Pads For Motorcycles
While originally created with medical applications in mind, the shock absorbing properties of this polymer are perfect for dozens of other products. It's used in gun recoil pads for hunters and cops. It's also used to manufacture jackhammer gloves, race car seats, and pads for injured horses. Remember Danny DeVito’s penguin suit in the movie "Batman Returns"? It was made from the same medical polymer we use to fabricate our custom motorcycle gel pads and gel seat pads. This soft gel makes the ride smoother by decreasing pressure points and increasing blood flow throughout your hips, butt and legs. Our special medical polymer is stable and cool — far better than an off-the-shelf silicone pad, which can generate and hold heat during the summer.
Back From The Boneyard
You'd be hard-pressed to find a more dramatic example of how we're able to transform a trashed seat into something good-as-new. Check out the "before" pics below. This Motobécane scooter seat was a mess. The cover was cracked and stained. The spindly grab strap was torn in two. The foam looked like it was chiseled from a Space Shuttle heat shield. Aside from the frame, we pretty much had to toss everything.
Trashed Motobécane Scooter Seat
Now, check out the bottom two pics. Hard to believe the restored scooter seat could have been salvaged from the remnants of the old seat. New motorcycle seat foam, new vinyl and a brand new grab-strap. Not only good-as-new...better!
Recovering Bicentential Bike
The Honda CB400F, commonly know as the Honda 400 Four, is a rare bike. It was only built for three years: from 1975 to 1977. The 400 Four has an air-cooled, transverse mounted 408 CC inline four cylinder engine. As you'd expect, it was only a matter of time before a 40 year old bike needed a new seat cover.
Recovered CB400F Seat
Attention To Detail
The owner wanted to maintain the bike's original look, so he purchased a 400 Four seat cover and had Mac's install it. There was some rust on the seat pan, but aside from that, everything was in good shape. Even the foam was still okay!
If you have an old bike, such as a Honda 400 Four, there are plenty of ways to recover the seat; go for an original looking cover, or have the seat redesigned to fit your body.
Turning A Double-Bucket Into A Street Fighter
This large double-bucket seat came to us from the owner of a touring bike. He liked the way it felt, but hated the "La-Z-Boy" look. We suggested turning the double bucket into a street fighter — a complete redesign/rebuild. After modifying the existing pan and motorcycle seat foam we added a custom gel pad and covered the seat with a carbon fiber smooth vinyl cover.
Street Fighter Style
Original Foam With Button Holes
Steamlined Without Button Holes
As you can see, the changes transformed the chunky looking "La-Z-Boy" into lean street fighter. The seat not only looks great, we did it without sacrificing comfort!
Lowering Seat Profiles
Bikers often ask us to lower their seats. Here's an example of why that sort of modification can be difficult at times. Check the side view of this Ducati seat. It looks like you could trim quite a bit, right? Now look at the top view where we've noted foam depth. As you can see, there's only half an inch of foam in places! Hard to trim this one down any further.
Don't Forget Your Passenger
This p-pad was raised two inches using seat foam and a custom-designed gel pad. The seat cover was designed with the original style in mind, so it perfectly matches the driver's solo.
Thanks to these modifications, the passenger rides more comfortably. They also enjoy the scenery and not just the back of the driver's head! We can widen, raise, lower and gel-pad your passenger seat so both of you enjoy the ride.
Motorcycle Seat Repair
It's easy to replace the seat cover for a standard mid-sized street bike, right? Not so much. In fact, even a relatively simple seat, such as this one, needs to be properly shaped and rebuilt before the new cover goes on — especially when the old foam is damaged and compressed.
Foam Separated From Seat Pan
Improperly Trimmed Foam
Done The Right Way!
After a valiant, but unsuccessful home repair, the owner brought his unfinished seat to Mac's. We matched his ideas with our experience to create exactly the seat he wanted. In this case, it required carefully rebuilding and beveling the foam before crafting the seat cover. Even something that seems straightforward, such as motorcycle seat repair, can turn into a big project without the proper tools and know-how.
Custom Seat Pan For Softail
Check out this custom-built seat we fabricated for a modified Harley-Davidson Softail. The marine-grade vinyl looks and feels just like leather; even the faux ostrich skin looks like the real thing. The tough vinyl not only wears well, it resists UV and water damage.

OEM Style Seats
Mac's enjoys a reputation for crafting unique motorcycle seat upholstery and custom fit gel pads – each designed to express an owner's individual personality. On rare occasions, riders prefer to maintain a bike's original look when the seat goes bad. You'd think an original style seat cover would fit perfectly. Unfortunately, that's not always the case. Seat foam collapses, fasteners rust and aftermarket covers sometime miss the mark.
OEM Style Suzuki Seat
Installing this OEM-style Suzuki seat cover was challenging for a couple of reasons. The fit was a little bit off and the underseat fasteners were going bad. After resizing the vinyl, we riveted the cover to the seat pan.
The seat cover was designed for the bike, but without these adjustments it wouldn't have fit properly.
Custom-Made Seat With Intricate Leatherwork
The talented leather craftsmen at Mac's are capable of building just about anything you can imagine. The design for this custom-made motorcycle seat was based on a photograph provided by the customer. The distinctive two-toned leather weave pattern covers a layer of simulated ostrich skin dyed blue.
Finely Crafted Leatherwork

Comfort and Beauty
While the simulated ostrich skin is manufactured from vinyl, it feels and wears just like durable saddle leather. With proper care, this handsome motorcycle seat will turn heads for a long time.
Custom BMW Motorcycle Seats
The patriotic owner of a 2000 BMW GS wanted to recover his bike's tattered seat in blue to go with its red and white tank. As he put it, "I want to Americanize my German bike". Done and done.

Before Seat Repair
Before recovering the seat in a sturdy vinyl, it was necessary to trim and replace damaged sections of the old foam. With the seat foam repaired, we recommended a marine-grade vinyl specifically engineered to resist fading and shed water. Stainless steel fasteners provide additional protection against water damage. As you can see, the custom BMW motorcycle seat turned out great. Love the color!
Custom Motorcycle Seat Upholstery
Custom motorcycle seat upholstery from Mac's not only fits your body, it fits your style — you select the cover, stitching and trim. And the sky's the limit! We can make it look any way you want. We carry a wide variety of studs and conchos. Custom embroidery is also available for a truly unique look. Click here to view a slideshow of selected seats.
Our motorcycle seat covers are truly awesome. We stock everything from durable, marine-grade vinyl to leather to exotic materials such as alligator, stingray and ostrich. Many come in wide variety of textures and colors.
Motorcycle Seat Repair & Seat Foam
This set of before & after pictures (below) illustrates our quality craftsmanship. The first two snapshots show a damaged motorcycle seat literally held together with duct tape. It's totally trashed. By the time we're finished repairing it, the seat not only looks brand new, it fits the rider like a glove. Count on Mac's to deliver unsurpassed craftsmanship. We're proud of our work and it shows.
Custom Seats For Jet Skis, ATVs & Snowmobiles
Durable Fabrics & Adjustable Seat Heaters For Snowmobiles, ATVs
Mac's Upholstery repairs, customizes and fabricates one-of-a-kind seats for jet skis, ATVs and snowmobiles. We're also happy to install off-the-shelf seat foam and inexpensive covers for riders not interested in a high performance seat.
In either case, our skilled craftsmen take extra steps to insure a superior installation. The process begins by drying, inspecting and repairing the seat foam. Damaged jet ski and snowmobile seats are often soaking wet when they arrive in our shop. It takes more time, but extracting all the moisture from the foam insures a better fit.
ATV Seat Heater
When completely dry, we sculpt the seat -- adding and removing foam as needed -- to fit your body. If you want a seat warmer for your ATV or snowmobile, the heating element is including in the fitting process.
We attach the fabric to the seat frame using evenly spaced, corrosion-resistant stainless steel fasteners. We often caulk the seams with silicon sealant to minimize water intrusion. When complete, your seat will not only look great, it'll fit like a glove.
So if you need jet ski seat upholstery, atv seat upholstery, or you need to repair a jet ski seat, Mac's Is the place to call.
