Check out this picture of the R25's speedo at 12,500 RPM. 173 kmh or 107.5 mph. So figure with the increase of 50cc's R3 will get 115 mph is MORE than possible 


just got to find a buddy with a truck to draft behind to break the 120mph barrierOn the comments from the 'exhaust sound' http://www.r3-forums.com/forum/489-yzf-r3-videos/3113-yamaha-r3-exhaust-sound-video.htmlvideo which there is a thread for already on here, the owner of the video confirms 115-118mph avg![]()
The rider is short shifting by 1500rpm in 4th and 5th gear.... this bike will easily pass 161km/hthis second video is almost exclusively onboard footage, at 3:53 you see it hit 164km/h and following lap you see it reach 161km/h at 6:18
