70
it will go 61mph
about 45-50mph
52mph
toped out it will hit about 125
Approximately from what I've found 90 to 120.
I don't know about the YZF but the YFZ has a top speed of 74 mph according to Yamaha.
the yfz 450 is not that fastest quad, Its not far from the top but raptors have more top speed. there is no 250 that will stand up to a yfz 450 stock
mine tops out at 62 with a fmf pipe.. so stock around 50-55
I heard the Suzuki has more top end speed but the YFZ is quicker
it is located on top of the engine behind the drive train, and you simply just twist counter clockwise to loosen and take off, it is the black cylinder on top of the engine.
They are on the top of your battery
