Not a bad bike Performance not the best but I bought the complete crank assembley including conrod and piston of the 450ECX Racing and fitted it to the motor and added a full White Brothers Titanium pipe. The diffarenc is magic,still sorting the suspension but a much better ride than the stock bike,remembering that this is a endero bike not a track bike but one can change the valves in the shocks to stiffen the suspension hence givving it better track performance.
