I was looking for a big bore two stroke and couldn't find what i wanted in a reasonable price range.  I expanded my search and found this at an excellent price.  it is basically the same engine in the gasgas 300 wild but at 250cc.

also, a 250r pipe will work on it so, that saves that agervation.

I was just curious. I have rode a 300 bike before. They have a nice power delivery.

yes.  it is the same bolt pattern as the 250r.  I found that interesting.  the engine weights about 20 lbs too.  the best part is the 50 hp stock.
