"We absolutely love our Speedster! We have put over 4000 miles with just maintenance and replacement of a few wear parts. It handles great and at a recommendation had it set up with disc brakes front and back and a thud buster. Only problem I have is sometimes the rear engine light comes on!" Jim W.
