2008 Honda CRF150R Expert, POWERFUL FOUR STROKE MINI !! EXPERT MODEL HAS LARGER WHEELS AND HIGHER SEAT ALONG WITH LONGER SWINGARM.. - Not all Mini racers are created alike, so for taller riders we offer the CRF150R Expert. Same great MX package as the standard CRF150R potent Unicam four-valve engine, fully adjustable Showa suspension but with bigger wheels, a touch higher seat, and longer swingarm to accommodate those young pilots who might have slightly longer inseams. Either way, big or small, the CRF150R's goal remains the same: dominate the Mini class.
