The commuter is powered by a 124cc air-cooled, single-cylinder engine producing 10.9hp and 10.9Nm, paired with a 5-speed gearbox.

The SP 125 features a TFT instrument cluster with Bluetooth connectivity, borrowed from the Activa 125, and gets an LED headlight. The bike is suspended by a telescopic fork and twin preload-adjustable rear shock absorbers, with braking duties handled by a disc or drum at the front and a drum at the rear.
