What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Yamaha Mt-09, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Brakes

From owner reports, verbatim
The front brake lever brake light switch is supposed to illuminate the brake light just before braking is applied (according to manufacturer’s manual). I realized when I was sitting on the motorcycle in my driveway, with the front brake holding the motorcycle, that the brake light wasn’t illuminated. As I began to test it I realized I was able to have the bike come to a complete stop without the brake light illuminating when using only the front brake lever. The motorcycle was purchased brand new and braking system has not been modified. I only had 300 miles on vehicle when this was discovered. I brought it to a Yamaha dealer as suggested in the manual if the light is not illuminating before braking pressure had been applied. The service mechanic at Donnelson Cycles in St Louis MO stated that this braking switch could not be adjusted. I searched for recalls and could not find any. This could cause a major hazard for someone especially if they are stopped using the front brake lever and the vehicle behind them does not know they are stopped or slowing.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
