Aprilia has unveiled new versions of its RS 125 sportbike and Tuono 125 naked motorcycles for 2021, though they won’t be making an appearance Stateside. The updates affect a range of elements, including the engine, electronics, and aesthetics.

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.
The mill sits inside a die-cast, twin-spar aluminum frame, and braking is provided by an improved system that features a four-piston radial caliper and 300mm disc at the front and single-piston, 220mm disc at the rear. The braking system is further improved by way of the new two-channel Bosch ABS system. Suspension is provided by a 40mm USD fork at the front and single shock at the rear, providing 4.3 inches and 4.7 inches of travel, respectively.

Both have a class-leading 3.8-gallon fuel tank and come with an underseat storage compartment. Riders can choose to have a USB charging port added on and can also upgrade either bike to include electronic quickshift. Lighting is full LED in 2021, and both bikes get new instrument panels that are compatible with the Aprilia MIA multimedia platform.
