I have no idea, But I kind of want to know the same thing will a yzf 450 motor fit in my Warrior 350 frame?
id say 450...
yzf 450 it handles better and is lighter.
YZF 450 puts out 39 hp stock.
It has 7 gears
130-140 km/h
130-140 km/h
1.13 liters
I don't know about the YZF but the YFZ has a top speed of 74 mph according to Yamaha.
CRF Or YZF 450 is a good choose.... not the x models the not a high strung...
try to look down by the motor mount, i ride a Factory YZF-450 that's wear mine is.
There is a dipstick. Look harder. It is a dry sump system and the oil is stored in an aluminum tank in front of the engine.
