gear ratio comparison WR450 / YZ450

[wr250rr]

Trail Rider magazine did a report on the YZ450F and said the YZ450 and WR450 have the exact same 4the gear. ? (14/48) The WR,s 5th gear is 14/50. They also said the YZ450F will go near 65 MPH at 10,000 rpm in 4th. And also the 1st gear on th YZ is 25% taller than the WR,s 1st. I just wanted to share a little factual information with yall.
