Does anybody know the top speed of a 2005 Yamaha YFZ450? thanks

 

70ish

 

My 2005 YFZ450 has a 1 tooth smaller front sprocket on it and the fastest MPH that I have gotten dragracing at one of the local IHRA 1/8th mile dragstrips is 73mph with the factory 20 inch tires.A few feet after I went through the traps I hit my rev limiter, so that was probably all it had in it.With the stock gearing I wouldn't be surprised to see maybe 5 more MPH, but that's just a guess.

The only mods that I have done are a DG slip on muffler, Pro-Flow Intake with a K&N filter and rejetted factory carb.I run 8.60's with a 1.90 60 foot time in the 1/8th mile (660 feet).

 

Ok thanks my brother is about to buy one and was wondering what the top is around...
