Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“It is transferring oil from the transmission to the primary while riding. This causes the primary to overfill which results in clutch issues and difficulty finding neutral. The transmission is going down which is probably decreasing its life and could cause it to lock up due to low oil level. This is potential safety issue that could lead to a catastrophic accident if this occurs at higher speeds. Bike has only 2500 miles on it and should not be doing this. No acknowledgement from the dealer.”
