October 29, 1985, Press Release, Honda launches 50cc land sports bike "Honda MTX50R" with improved performance

Honda Motor Co., Ltd. has improved the power output (from 6PS/6,500rpm to 7.2PS/8,500rpm) of its land sports bike "Honda MTX50R," which is equipped with a water-cooled, two-stroke, single-cylinder (49cc) engine that allows for comfortable riding on rough terrain and in urban areas, and will release the new model on November 1st.




The engine installed in this MTX50R adopts a four-leaf reed valve with a straightening plate that brings smooth intake to the inlet port, a hemispherical combustion chamber with excellent combustion efficiency, and a balancer that reduces the vibrations unique to two-stroke engines, achieving both powerful and smooth riding.

The transmission is a six-speed transmission that allows a wide range of appropriate gears to be selected depending on the riding conditions. The suspension is a telescopic type for the front wheel and a popular Pro-Link type for the rear wheel. In addition, the cushion stroke is 200mm for the front wheel and 170mm for the rear wheel, providing excellent road-following performance from rough ground to paved roads.

The frame is a full-fledged semi-double cradle frame that maintains high rigidity even when subjected to strong shocks when riding on rough terrain. In addition, the slim body has good foot placement, and the seat is laid out all the way to the top of the tank, allowing the rider to ride in an appropriate position depending on the road conditions.
