Fitment: This is a custom motorcycle component that requires basic fabrication skills and mechanical acumen to install properly. If your motorcycle already has a seat hinge and spring bungs installed on the frame, you’re halfway there, though some additional modifications may be required. Our Slimline seat looks best on bikes with steep backbones and short rear ends, such as many Japanese and British chops, and many rigid H-D XL’s.

Construction: Heavy gauge stamped steel pan with high rear kick for added support. Stamped-in ridges on the pan increase stiffness and give the pan a clean, classic look. Matte black electroplated finish. Cover is hand stitched heavy-duty vinyl and is fastened to underside of seat pan with rivets for durability. Foam is molded polyurethane, approximately 1” thick.

Note: Our seat covers are extremely water resistant, but the seams are not. If left outside in the rain, these seats can soak up water. This is especially true of the Diamond or Tuck n’ Roll designs since they have more stitched seams. If you expect rain or snow, cover the seat to keep your saddle dry.

Installation details: A unique adjustable carriage bolt system on the underside of the seat pan allows you to fine tune the location of the seat hinge and both springs. This is especially helpful if you are installing our Slimline seat on a frame with preexisting spring bungs welded onto the rear cross member. This is not a bolt-on product.

I had a slimline for my first sporty and I loved it then. I just bought another for my current hardtail sporty. This seat has the most incredible padding and material. I ride daily to work and I take the same route everyday. The padding is soooooo comfortable the bumps and dips are like nothing now. Biltwell always lives up to their motto and name.

Great quality product, slick looking, comfy too. The motorcycle lives outside at the moment sadly and this seat seems to resist the elements quite well!

I ordered the black diamond solo seat, along with the black chromoly seat hinge. Although I have yet to weld the seat hinge on my frame, I must say that the quality of the seat and hinge are second to none. Biltwell truly lives up to its name. I previously ordered a La Rosa spring seat and sent it back due to its odd color and requested a replacement. I ultimately had to file a claim with my insurance card company because the seller of the seat never responded to me after I sent the seat back and requested a replacement. The Biltwell seat is not only less money than the La Rosa seat, but seemingly of higher quality. What you see on the webpage is what you get, and I would highly recommend the Biltwell seat products to anyone looks for a custom spring seat.
