Can someone tell me what the top speed of my 86 ATC 250R is, it is stock

 

I can tell you that with just an aftermarket pipe a 12 tooth front sprocket and 20inch ohtsu's mine does 73 on the gps. It is kind of hard holding a gps at 73 mph though. A guy on another site said he has an old dirt wheels and they tested all the 250 2-strokes and the 250r was the fastest at 76mph. Thats pretty usless so I geared mine down a little bit to spank the banshees in short drags.

 

I raced a motocycle and was pushing 75 mph in a corn field. All stock except reeds, bored .040, and silencer.

 

In the 1986 issue of Dirt Bike in which they tested the new 250R they said it had a top end of around 75mph
