A robust machined aluminum 15-tooth pulley engineered for Works'91 TeamSpec fitment. The YZ-630W2 provides enhanced wear resistance versus stock components while retaining original mounting geometry for a straightforward swap.
Intended to influence gear engagement and transient response rather than cosmetic appearance, this pulley is typically selected during tuning or as a maintenance upgrade. After fitting, double-check gear mesh and alignment to avoid uneven wear over time.
