Most of you probably already know about this, but I just discovered it. Has every bike ever made, with pictures, stats (even the elusive horsepower figures most manufacturer's do not disclose), ratings in every category, and ability to compare one bike to another. This is extremely helpful for someone like me looking to get the quick and dirty on one bike compared to another.
There are some flaws thoguh. I compared the 2007 Aprilia SXV 5.5 to my 1997 DR 350 SE and it actually said my bike was the better bike. Even said the DR had better engine performance
