Yamaha Xmax 300 Guide Stopper 2 (B74-E2241-01)

The Yamaha XMAX 300 Guide Stopper 2 (B74‑E2241‑01) is a genuine‑style internal engine component designed to help guide and position mating parts within the powertrain assembly. Working in conjunction with other engine or transmission guides and stoppers, this part controls movement of shafts, levers, or sliding elements to ensure they follow the correct path without unnecessary lateral play.

Manufactured to Yamaha’s original specifications, Guide Stopper 2 is made from durable materials that can withstand heat, vibration, and repeated mechanical stress. Over time, the original guide stopper can wear, deform, or lose its ability to keep components precisely aligned. Replacing it with this specified stopper restores proper part alignment, reduces unwanted movement, and supports smoother operation throughout the engine or transmission. Proper alignment and control of moving parts help extend service life, reduce noise and wear, and maintain reliable mechanical performance.
