What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving down barker cypress I was approaching a light. I started downshifting and applying my rear brake. When I pressed down on the rear brake, there was a thug then nothing, no grip, no tightening, nothing but air. I did not have brakes.
The contact stated that while driving 35 mph, the vehicle stalled without warning. The vehicle was restarted and began to lunge violently. As the contact tried to regain control of the vehicle, another vehicle crashed into the contact's vehicle. The contact sustained a fractured shoulder.
The contact attempted to accelerate, but the motorcycle lost speed and stalled. The contact replaced the battery, but the failure recurred. The motorcycle was taken to an independent mechanic who diagnosed that the ecu failed and needed to be replaced. The motorcycle was not repaired. A dealer was not contacted.
Motorcycle keeps stalling as I slow down. I'm an experienced rider and have never had this issue with any other motorcycles. Engine dies when down shifting, I've almost been hit a few times when I'm trying to turn and it stalls.
Every area of the entire tire tread is severely dry-rotted a second time and yet I've only had the tire 5 months.
The contact stated that while driving approximately 30 mph, the vehicle stalled without warning. The manufacturer was not made aware of the failure. The vehicle was not repaired. The vin was not available. The approximate failure mileage was 2,050.
