WeBike Japan. Period. "MAYBE" MSXsport(?) It is truly beautiful, in a Carbon Fiber sort of way. The fit is perfect on the bike, as the stock pan was obviously used as the indents from the seat strap are still visible. They pretty much bought a stock seat and got busy with it. Very nice job with the foam as well as the cover material and stitching. More comfy. Keeps your butt forward, GREAT for center of gravity on the bike. But...if you are a big dude it may be too far forward. I would say anything over 30" inseam.
