Nice cover, good traction to prevent slipping. A little tricky to install properly, but much easier with a pneumatic stapler.
Bought for 2008 YZ450
Installation was a huge pain. I have installed seat covers before so I knew that I would probably lose my temper a few times. However, I don't believe that the cover was designed to accommodate the bump. Even with two of us pulling, stretching and stapling, we could not get the wrinkles out and there is an empty space at the beginning of the bump. It does not look good on the bike. The cover probably fits great without the bump. The seat bump functions as advertised, but the installation is no good. If you don't care how the bike looks and like the bump, get it. If you care how the bike looks and are on the fence about the bump, I recommend getting the cover without it.
This seat not only looks bad azz on my '08 Yamaha 450 but the bump is a must have on today's 450s. The seat grips well enough, matches my factory blue and looks trick but the bump really holds you in the saddle when you're hard on the gas. I knew I was constantly sliding forward on my bike before (I had the monkey butt to prove it) but I didn't realize just how much until I installed this bump. Great buy!
Easy install, Gips excellent to my buttocks. Everything is awesome except to color does not match the factory plastics, but I don't really care about that.
