The 2009 MY brings solid upgrades for the middleweight RM-Z machine. The RM-Z250 receives a new chassis with a ton of design tweaks for better rigidity and lighter mass, new adjustable Showa suspensions and gold-trimmed accents for a true factory look. On the engine side, the RM-Z250 sees a new Keihin FCR73MX carburetor, new porting, a new internal muffler design, a new piston profile and a hot starter relocated according to Ricky Carmichael's own design.
The seat was also improved for better grip, while the pegs were redesigned to prevent mud from caking up, and the rotors now boast a race-inspired shape for better cooling and mud rejection.
