What size 4 stroke dirt bike would greatly vary your top speed. A 125 4 stroke will top out around 48-50 mph while a Honda XR 650 4 stroke top speed is just a bit over 100 mph.
No we can't use 100cc 4 -stroke dirt bike race against 85cc dirt bikes.
100cc 4 stroke motor bike
old school bikes had 3 or 4 speed, then they got five speeds later,but todays bikes can have 5 or 6 speed now.
No. I have a 100cc kx 100 2 stroke and i can race 450's and beat them. 2 strokes are faster off of the starting line and in a straight away race, but after maybe a mile 1/2 the 4 stroke will win
depends 2 stroke of 4 stroke and racing bike or a trail bike
the top speed of a 150cc dirt bike can depend on a lot of things like if its a 2 stroke or a 4 stroke engine what kind of terrain your on and how much you way but the average is about 50-55mph
I think 60mph to 65mph approx. is the top speed for this bike.motorcyclesdir.com/
Approximately 45mph to 55mph is the top speed of this bike.
2 srokes have powerband (response) and they rev higher = more power
Take out the top speed restrictor plate. If you don't know how to do it contact a proffesional. where are the restrictor plates located
2 stroke, more power and torque = more speed 4 stroke, more reliable
