Depends on the make and model of the bike. Some Motocross bikes have 4 gears while most of the cross country thumpers are 5 or 6 speeds.
Two strokes can accelerate faster but it depends on engine size
Yamaha TTR 125
CRF 150 R
One down four up
cr 80 is a two stroke. crf 80 is a four stroke.
that engine code is not a four stroke, its 2 stroke 80cc
it smokes out the exhaust...
A street legal dirt bike is any dirt bike that has a four stroke motor, head lights, brake lights, turning signals, a spark arrestor in the silencer, and street legal on-off road tires.
is the question being answered?
i would say i two stroke because two strokes are much easier to fix, there faster and better.
