how fast will a 1981 ts250 go....
yea stock bike , how fast till it go *topspeed* engine code x air cooled 248cc engine... i dont care other then how fast it will go.. not if you got one impounded...
With completely stock gearing and a relatively lightweight rider in tuck position I'd agree with 65mph. These are geared pretty low from the factory and you could potentially get another 5 mph with 1 tooth bigger front sprocket, but it will not be as smooth at slow speeds.
