    Since the TRX has a cast piston and steel valves I would have to believe it would be way below the CR.
    The CR has a forged piston and Titanium valves so it should be capable of much higher rpm.
    Plus Honda is always real conservative on their ATV's.
    Maybe they will surprise us though.
