i recently bought a brand spankin new kawasaki kmx 125..and after a few teething problems (including a knackered oil pump) she´s running beautifully. It is VERY important to keep those revs down when runnin one of these in. i´ve heard that if not properly run in, a new engine is needed after 2000 miles...eeek. All in all a joy to ride...beats any car at the lights. GET ONE!!!
