is there any diffrence in the dt200 and dt250

I Would Imagine That The Bore on the Piston is Bigger , or a longer Stroke

The DT200 is a capable, recreational bike, and has been used in enduro competition with some limited success, although it was never intended as a competitive racer.This machine is a stealth:at motorcycle event sound tests it registers between 74 and 82 dbA. Meeting noise level requirements has never been an issue.

The DT 200 shares its engine cases with the ATV BLASTER - the blaster was an air cooled model but the crank rod and Piston are the same. In the blaster version the water pump is not installed but rough in are there, with plugs in the case.

Not mine but similar.
I had one back in the 70s. It was terrible. Barely wheelie in 1st gear! Heavy, no suspension travel.
I raised the exhaust port and made a pipe for it. Wheelies in 3rd. Still not a great bike. No powerhouse.

I also owned a DT200. As rough as this bike is, it is much better than my DT250 ever was for ride and power. Still nowhere near a KTM!
