Hayabusa Starter Motor
STR-BUSA-02 Hayabusa starter motor STR-BUSA-02

Brise have developed a special high torque starter motor and drive gear for the Hayabusa which is suitable for engines with the later wider starter casting, 2003 onwards.

Ideal for use on high compression engines where starting is quite often difficult with the standard starter.

The latest design has an increased diameter output shaft which adds to the strength of the unit and it has a redesigned gear ratio to improve the cranking speed. The starter motor kit comes with a new starter motor and secondary drive gear. It has a built in sprag clutch for safety & is a direct bolt in replacement for the original unit on 2003 onward engines with no modifications required.

Shown above right on our display engine with the cover off showing the drive gear.
