1984 |RA125

High-performance inherited from the RA, winner of nine consecutive Motocross World Championships

RA125

The RA125 inherits the high performance of the renowned RA factory machine that won nine consecutive titles in the 125 cm³ class of the FIM Motocross World Championship. The newly designed 2-stroke liquid-cooled power reed valve engine generates class-leading maximum horsepower of 22 PS. This high-performance power unit includes a highly efficient liquid-cooling system, flat slide carburetor, and multi-stage expansion type muffler with excellent exhaust efficiency. The semi-double cradle frame adopts high-tensile steel pipes to realize both low weight and high rigidity. The long stroke suspension includes the Full-Floater suspension and a square aluminum swingarm at the rear. Combined with features such as a hydraulic front disc brake and low profile tires, the RA125 is a true high-performance off-road machine.

1989 |TS125R

Adding a sense of fun to hardware directly descended from the RM series

TS125R

The TS125R was developed based on the RM series of motocrossers that had achieved great success in the All Japan Motocross and AMA Supercross Championships. To ensure performance that meets the needs of a wide range of applications from city streets to unpaved roads, a newly designed 2-stroke liquid-cooled 1-cylinder engine equipped with a crankcase reed valve and the Automatic Exhaust Timing Control (AETC) system was adopted alongside a slingshot carburetor, delivering high power and torque throughout the whole rpm range. In addition to front and rear disc brakes, the new link-type Full Floater Suspension was adopted at the rear. The TS125R combines a slim form inherited from the RM series that facilitates shifts in rider weight with a low center of gravity to realize superb maneuverability.
