The Taida GY6 Short Case crankcase is an aftermarket engine case designed for 70mm GY6 engines used in Honda Ruckus GY6 conversions. It is distinguished by its more compact length compared to standard or "long case" crankcases, while maintaining 57mm internal clearance for the crankshaft and internal components.
This engine case forms the basic structure of the engine block, providing:
crankshaft housing
bearing and shaft positioning
internal oil passages
mounting of lower engine components
The short case version is particularly suitable when:
a compact configuration is desired (less lateral bulk)
a more centralized engine mounting point is required
the chassis geometry requires close coordination between the engine and transmission
