2025 Yamaha MT-09Transmission & drivetrainEngine & cooling

Clutch feel felt off from delivery. The friction zone of the clutch was tight and there was a pulsating vibration when the clutch tried to engage. Thought it was normal for this bike, turns out it wasn't. Got worse as riding over 3500 miles. At 3500, under dealer inspection, advised that the clutch plates needed to be replaced as they were "sticking". Yamaha denied warranty because it is a "Wear item", however this issue was present at delivery. Additionally, almost caused several tip overs because the clutch engagement was not smooth. This lead to instability on hill starts in traffic.

I was making a right turn in 1st gear and applying small throttle for traction but the engine cut off during the turn. This is dangerous for a motorcycle as friction and throttle is needed for a safe turn even during slow speeds. I have raised the concern to a local dealer prior to this incident. I called the local dealer and they stated that the open recall had already been completed so there is nothing else to do. There are a few youtube videos and many comments about this being a common issue.
