The MB model was standard equipped with a speedometer, rpm counter, front disc brake, two stroke oil injection system and Honda Comstar wheels.
Because of its success Honda released the MT series, a naked off-road version, on the European and South African markets.
The MT series earned its popularity because of the large numbers of original and imitation parts that were available, the fact engine parts from the restricted models could easily be replaced with those from an unrestriced model and its off-road ability due to high ground clearance.
In parallel with the MB and MT series, Honda released air-cooled MBX, MCX50/80 and MTX 50/80 cc models.
Unlike the MT50 which had a 4 or 5 speed gearbox depending on the exact model and country code, the MTX50 had a 5 or 6 speed gearbox and in some cases a HERP chamber on the exhaust, again all depending on the exact model and country code.
During the entire production years from 1983 onwards of the MTX and MBX only small improvements and cosmetic changes were made.
