The Best Cafe Racer Seats, and How to Fit One
The best cafe racer seat is the one that fits your frame. Most cafe seats sold online are universal: it needs a flat rear frame, usually finished with a seat hoop, and some fabrication to mount. Pick the style first (hump or flat brat), measure your frame, then choose a seat whose stated size and hardware match.

DKMOTORK 0393 Hump Cafe Racer Seat
The look most people picture: a gloss black shell with a brown pleated cushion and a rounded tail hump. The listing says it is made of leatherette, ABS plastic, foam and iron, ships with three brackets, six bolts and six nuts, and its title states that subframe modification is required.
Rich Choices Vintage Hump Seat (CB350 to CB750)
An all-black hump seat whose listing names the Honda CB350, CB400, CB500, CB550 and CB750 alongside Yamaha SR/XJ and Suzuki GS/GN/GT models. Useful detail: the seat has six M6 threaded mounting holes and comes with three removable brackets. "Listed for" still means measure first; see the fitting guide below.
TADAFA Brown Hump Cafe Racer Seat
Brown pleated cushion on a matte black base. Two things set it apart in the listing: it states its size (about 53 cm long, 25.5 cm wide, 13.5 cm high), so you can check it against your frame before ordering (the separate size field on the listing gives larger figures, likely the packaging, so confirm with the seller), and the cushion lifts off the base so the base can be painted to match the bike.
DKMOTORK Brat Flat Seat (Black)
If you want the long, flat brat line rather than a hump, this is a straightforward option with a stated size of 62 x 25 x 9 cm. The listing is clear that it is not made for any specific motorcycle and that the frame needs modifying to fit it, which is common for universal flat seats.
Remaiw Diamond Flat Brat Seat
Same flat brat shape with diamond (quilted) stitching instead of pleats. The listing says it suits bikes with a flat rear frame, names Honda CB, Yamaha SR/XJ and Suzuki GS as examples, and includes three brackets with six bolts and nuts.
FINMOKAL Universal Cafe Racer Seat
An all-black hump seat with a longer tail section (the listing calls it a scrambler saddle, but the photos show a cafe-style hump). It lists a long run of flat-frame bikes, including the Honda CB750, and notes that no installation instructions are included, so plan the mounting yourself.
The part most builds also need: a seat hoop
Tbest Rear Seat Hoop (curved, 210 mm)
A bent metal loop that closes off the back of a cut rear frame and gives a cafe seat its mounting point and tail shape. The listing offers flat and curved versions in several sizes and says modification may be required to mount it. Hoops are typically welded to the frame rails, so budget for a welder unless you weld yourself.
Hump or flat brat: which style suits your build?
A hump seat is a short pad that ends in a tail cowl. It is the classic cafe racer silhouette and pairs with low clip-on bars and rear-set footpegs, because it holds you in a tucked, forward position. A flat brat seat is longer and level, tends to look lower and usually lets you move around more, which tends to suit higher bars and a more upright position. If you are still deciding on the riding position of the whole bike, our cafe racer pros and cons and bobber vs cafe racer guides cover how each style rides.
How to measure for a universal seat
- Take the stock seat off and look at what is underneath: battery, regulator, fuses and wiring often live there and will need a new home.
- Measure the usable length from the back of the fuel tank to where you want the seat to end.
- Measure the width across the outside of the frame rails at the front and the back of that space.
- Compare with the listing. Only some listings state dimensions (two on this page do). If one does not, ask the seller before buying.
- Check clearance: with the bike's weight on it, the rear tyre must not touch the seat base or hoop at full suspension compression.
Fitting it: what the job usually involves
On most bikes, fitting a cafe seat means removing the old rear frame loop or seat brackets, making the rear rails level, closing them off with a seat hoop, then mounting the seat with the brackets supplied in the box. Before any cutting, find a new place for the battery and electrics (a small battery box under the seat or a lithium battery are common answers), keep a legal rear light and brake light and a mounted, legible, lit number plate (rules vary by country and state), and check what your state or country says about frame modifications. The cutting and welding is the step to hand to a professional if you are not confident: a badly welded subframe is a safety problem, not just a looks problem.
If you would rather not cut the frame at all, a seat cowl that fits over the passenger half of the stock seat gives a solo look and can be removed later. It is the reversible option; a full cafe seat is the more involved, permanent build.
Cafe racer seats: FAQ
Will a universal cafe racer seat bolt straight onto my bike?
Almost never. Four of the six listings here say outright that the frame or subframe may need modifying, and the other two do not promise a bolt-on fit. Some stock frames rise or curve at the back, and the stock seat area usually carries the battery, wiring and rear light, while a cafe seat wants a flat, level rear frame. A direct bolt-on fit is rare, so plan on some fabrication or on having a shop do it.
Do I need a seat hoop for a cafe racer seat?
Often. If you shorten the tail, a hoop is the usual way to close it off. A hoop is the curved tube that closes off the end of the rear frame, gives the tail its clean shape and gives the seat something solid to mount to. On most builds it is welded to the frame rails after the old rear section is cut, so it is a job for a competent welder. Cutting or welding a frame can also affect registration and inspection where you live, so check that first.
Hump seat or flat brat seat?
A hump seat (a short pad ending in a tail cowl) is the classic cafe racer look and tucks you into a forward position. A flat brat seat is longer and level, with a lower, more relaxed look, and it usually leaves a little more room to move around. Pick the one that matches the riding position of your build: low clip-ons and rearsets suit a hump; higher bars suit a flat seat.
Can I carry a passenger on a cafe racer seat?
Not on a hump seat: the tail hump takes the space a passenger would use. Some longer flat seats physically have room for two, but that only matters if the frame, subframe, footpegs and your local rules allow a passenger. Treat any seat on this page as a solo seat unless you have checked all of those.
How do I measure my bike for a universal seat?
With the old seat off, measure the usable length from the back of the fuel tank to where you want the seat to end, and the width across the outside of the frame rails at the front and back of that space. Compare those numbers with the dimensions the listing states. If a listing gives no dimensions, ask the seller before ordering rather than guessing.
Is a seat cowl the same as a cafe racer seat?
No. A seat cowl is a hard shell that covers the passenger half of a stock seat to give a solo look, so it keeps your original seat and frame. A cafe racer seat replaces the seat entirely and usually needs a flat frame and a hoop. A cowl is the reversible, no-cutting option; a full seat is the more involved, permanent build.
