what makes you think it was a small bike?

nice find on that video too

thats pretty intense! wonder if those numbers were in miles or kilometers.

probally kilometers cause he's movin but not as fast as the speedo is sayin cause things go blowin by real quick at that speed i'll need to get my bike out or my nova and make a movie at those speeds
