The yz would always win because its a 2 stroke race bike. Even the yz85 would beat the crf150r or the crf150f.
I would look for a nice used yz125 to start out with. There are a lot of them and they were top of the class for a long time. The crf150 answer was stupid.
a yz would own a crf
CRF150: 11.2 hp.
According to BBR a stock CRF150 has 11.57HP.
the cr could probably trail close behind it but only if you have done it up will it beat it
Well a Kx85 would beat it because of its power band and acceleration
no
I have a crf150 and it has almost reached 70MPH but i didnt have the throttle all the way in.
no.
top speed of a yz125 in mph
Obviously yz125 is more faster than yz85.
all yz125's are 2 strokes
