Yamaha - Dog Clutch - Gear Engagement System - 69G-45631-00-00

Overview

If you’ve ever felt a hard shift or heard grinding going into gear, the dog clutch is usually where the problem starts. This part is what actually locks your gears in when you shift, so it takes a lot of abuse over time. On Yamahas, when it’s in good shape, shifting feels solid and clean without hesitation. When it’s worn, though, you’ll notice it right away—especially docking or moving in tight spots.
