Starting with the engine, both models benefit from a revised 124.2cc single which features an updated combustion chamber, new intake and exhaust ducts, and a new iridium spark plug. Valve function is updated to optimize the new intake system, and the throttle body is repositioned to help improve airflow to the cylinder head. There’s a new exhaust system as well, all contributing to more aggressive torque delivery. Peak power also comes on lower in the rev range. The bikes get a new Marelli MIUG4 ECU and revised final drive.
