Important: Honda introduced a revised 157cc eSP+ SH150i engine for the 2020 generation, with a different 55.5mm stroke. This crankshaft should not be advertised as a direct replacement for the 2020-and-later engine without separate technical verification.

The Ruizheng Racing Honda SH150i Crankshaft Assembly is intended for aftermarket replacement and wholesale engine-parts sourcing.
The supplied configuration must be checked against the original component, including the crankshaft assembly dimensions, connecting rod specifications, shaft-end design and relevant mounting requirements.
Material grade, hardness, bearing inclusion, dimensional tolerances, crankshaft runout and inspection requirements should be established through approved samples, drawings or production specifications.
