Technically, the Aprilia SX and RX 125 on the same basis. Visually, they go their separate ways. The look and feel in the Supermoto style is trendy on the SX 125 with its 17-inch spoked wheels. With its 21-inch front wheel and 18-inch rear wheel and large-tread tires, the RX 125 is clearly aimed at off-roading.

Extensively revised engine

The 124 cm³, liquid-cooled single cylinder was trimmed to the Euro 5 standard for 2021. This required a completely new cylinder head with a redesigned combustion chamber and modified intake and exhaust ports. A powerful iridium spark plug ignites the gas-air mixture. The profile of the camshafts, the bucket tappets and the valve springs have also been changed. The throttle valve has also been repositioned to optimize the intake air flow. Changed air intake ducts and a new air filter round off the changes in the intake tract. On the exhaust side, the engine was equipped with an even more effective catalytic converter system and a new stainless steel silencer.

It continues to generate 15 hp, which is already 700 revs earlier at 10,000 revs, and thus fully exhausts the class limit. At maximum torque he had to give up a little. Instead of the previous 11.3, there are only 11.2 Nm at 8,000 tours. In combination with a new engine management system, consumption should also have decreased.

New look, increased prices

New body parts make the 125 look narrower and slimmer. The redesigned tank and the seat merge seamlessly and thus optimize the driver’s freedom of movement. There are also modernized graphics. Otherwise, the 125 series stayed true to their high-quality equipment.

It is available Aprilia RX 125 in the 2021 season in the colors Silver Speedway and Rally Tribute. The SX 125 is available in the colors Silver Speedway, Rally Tribute and Red Raceway. Both light motorcycles have been available since February. The prices are all at 3,990 euros, which is 220 to 360 euros higher than the previous model.
