What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Center fork bolt, which bolts the fork of the motorcycle to the frame, became loose. Was cautious of this happening as it happened to a friend who bought the same make, model and year of motorcycle, though we assumed one time. Once the odometer hit 2400 miles the bolt began to spin off.
Tach shows rpms 1000 rpm higher when warm up. When the motorcycle runs to operate temp the engine stumbles between 7500/9000 rpm could cause me to crash feels like the motor will foul out. Idle increase by 300 rpms.
