The dual shock setup contributed to consistent traction over uneven ground, a key advantage for off-road racing.
Transmission and Drivetrain
A 6-speed manual gearbox supplied power to a 2:1 gear ratio differential. The transfer case was designed to provide a 70 % front-drive bias, optimizing traction during acceleration and cornering. The drivetrain was engineered to minimize weight while maintaining durability under high torque loads.
Braking and Safety Features
The vehicle incorporated dual hydraulic disc brakes - 320 mm in diameter at the front and 260 mm at the rear. Anti-lock braking system (ABS) was not standard on the ATC250R; however, some aftermarket kits were available to enhance stopping performance. A rider seat with adjustable height and a side-mounted storage compartment were standard safety and convenience features.
