All GAS GAS parts

GAS GAS MC 300

MC 300 punches above its weight. Light chassis, brutal power delivery, and a top-end that rewards riders who keep the throttle pinned. Keep the two-stroke healthy with the right top-end kit, fresh reeds, and a sharp clutch. Suspension internals take a hammering on big jumps. Plastics scuff fast. Stock the parts that go first and ride harder.
