The engine was air-cooled with a fuel/oil mix and Posi-force lubrication system. The bike had a single, high drawn exhaust and used a Mikuni VM28SH carburetor. It could produce a maximum power of 17.2 kW / 23 hp at 6500 rpm and a maximum torque of 26.5 Nm / 2.7 kgf-m / 19.6 lb-ft at 5000 rpm. The clutch was a wet, multi-plate system with a 5-speed, constant mesh transmission and chain final drive.

The Suzuki TS250 was a capable off-road motorcycle that offered a reliable and powerful ride. Its lightweight design and maneuverability made it suitable for various terrains. However, its drum brake system could be tricky to use in extreme conditions, and riders had to be cautious not to overheat the engine due to the fuel/oil mix system. Overall, the TS250 remains a classic model that paved the way for future Suzuki dirt bikes.
