February 25, 1982, Press Release, Honda releases MBX50, a road sports bike with authentic class and texture

 Honda Motor Co., Ltd. will release the Honda MBX50 on March 1st. The new bike has the class and feel of a true road sports bike, and offers a relaxed ride.







The MBX50 has a long wheelbase design (1255mm) that allows for a comfortable ride in a relaxed riding position that reduces fatigue not only in city driving but also in long-distance touring.

In addition, the large 12L fuel tank, front fender with air guide, turn signals integrated with the rear cowl, tail lamp, etc. further emphasize the bike's status as a full-fledged sports bike.

The engine is a newly designed water-cooled two-stroke 49cc engine that uses technologies such as Honda's unique four-leaf reed valve with a straightening plate, which improves ease of use in the low and medium speed ranges. It has excellent fuel economy (73.0km/L, 30km/h constant speed test value), and coupled with the large fuel tank, it makes long-distance touring enjoyable.

In addition, the body uses a high-rigidity semi-double cradle frame using ultra-high tensile steel around the head pipe, and has a lightweight design (dry weight 79kg) that is easy to handle.

The rear suspension is a Pro-Link type that has already been adopted in high-end sports cars and has been highly praised. This, combined with the large diameter 29φ front forks and lightweight aluminum boomerang-shaped Sports Comstar wheels, provides excellent manoeuvrability and ride comfort.

The front brakes use Honda's unique dual piston calipers, providing excellent braking performance.

In addition, the bike is fully equipped with a 12-volt, 3-amp battery, a large rectangular headlamp (35 watts), and a highly visible translucent meter with illuminated needles.
