111 gag dop
to slow for my 400
3,5hp
I would say 74 to 80. Depending on the riders weight gearing. If it has a aftermarket exhaust or cam or anything like that. P.S. Yamaha is the best.
no only in 09 the yfz450 and the 09 yfz450r
fast
if it is a Yamaha wolverine 450 it will go 61mph
a Yamaha blaster can go around 75-80
155mph
Not that fast but about 50 with no upgrades
the Yamaha ttr125 goes about 50 to 55 mph
about 70mph
