The design incorporates many cooling fins to keep the temperature under control whilst the internal porting ensures optimised gas flow.
To ensure a perfect seal, when the carburretor is mounted, the opening for the carb has been fitted with a rubber o-ring whilst to enable the smoothest possible movement of the crankshaft the casing has been fitted with Swiss-made high quality bearings.
For looks, the side of the crankcase sports the new Mega Symbol on the front side and the ZX21 logo on the rear side.
