First introduced a little over four years ago, the KLX230R is Team Green’s highest-displacement air-cooled trail bike. The 233cc four-stroke engine uses a two-valve cylinder head fed by a Keihin 32mm throttle body, and is slightly oversquare with a 67.0mm bore and 66.0mm stroke. Compression ratio is 9.4:1. The last time we dynoed the KLX230R, it was a 49-state model, which weighs 8 pounds less than the 50-state (California-legal version) machine on our automotive scales (253 pounds wet versus 261 pounds wet). We also found out its engine produces 0.8 hp and 0.7 lb.-ft. of torque more at peak.
