Honda Motor Co., Ltd. will release the Honda MBX50, a road sports bike equipped with a water-cooled, two-stroke, single-cylinder (total displacement: 49 cm3 ) engine, on April 21st, which can be used for a wide range of purposes, from entry-level models to general road touring.
The engine installed in this MBX50 adopts a four-leaf reed valve with a straightening plate that provides smooth intake to the inlet port, a hemispherical combustion chamber with excellent combustion efficiency, and a large exhaust chamber, which together provide powerful torque characteristics from low to medium speeds.
The body design adopts a body size (wheelbase: 1260mm) that allows for a relaxed riding posture. The frame is a lightweight, high-rigidity semi-double cradle frame. The rear suspension is a Pro-Link type that is well-received for its excellent road-following ability, and the front wheel brake is a hydraulic disc brake with Honda's unique dual piston caliper. In addition, the front and rear wheels are equipped with lightweight boomerang-shaped all-aluminum Sports Comstars, making it a fully equipped road sports bike.
Honda's 50cc class sports bikes now include the MTX50R land sports bike, the TLM50 trekking bike, and the MBX50, and are able to meet the needs of a wide range of customers, from on-road to off-road.
