This is an RC-scale aluminium spur gear intended for Kyosho Fazer Mk2 FZ02 on-road models. The 68-tooth profile corresponds to the original large gear role within the transmission and is supplied in a gun metal finish to suit popular upgrade styles.
The component is aimed at replacement and tuning work: fitting an aluminium spur in lieu of a worn plastic one can modify mesh behaviour and change how wear develops across gearbox elements. Use it when refurbishing the drive, setting precise gear mesh, or as a more robust spare for events.
Standard on-road spur fitting applies: remove the gearbox cover, check mesh with the motor pinion, and retain the spur using the existing hardware. Confirm correct backlash and unhindered rotation prior to final drivetrain reassembly to avoid early tooth damage.
