about 280 on sand wit a dirty little breeze,
one fart and i was off, boooooooooom

 

The fastest I ever went on a dirt bike was when I raced my sister's boyfreind with a datsun pickup on my RM80 I BEAT HIM.seriosly.He said he was going about 50 and i was ahead of him.It was a short race though.About a 1/8 mile.That thing is fast for a 80.IF anyone wants it they can have it.IT needs main crank seal and a new part to the sidecaseing where the water line goes into the sidecasing.It bolts right on.But come get ifm U want it.

 

My 400ex 2000 can go 75
