Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“1. Bike was badly hesitating starting off in 1st gear from a stop. 2. Turning the throttle to accelerate would sometimes pitch me forward on the start as the engine hesitated, then turning it a bit more would almost throw me off as it accelerated. 3. One dealership tried adjusting the throttle position sensor (tps) and it actually made the problem worse. The next dealership replaced the tps unit and it has been running fine since.”
NHTSA complaint #10118730, filed 2005-04, 4,400 miles“The motorcycle had progressively worse stalling at stop-lights and stop signs. At times the motorcycle would stutter and stall when trying to initiate the throttle from a stop, and at other times the motorcycle would randomly increase speed while cruising on the highway. The throttle became quite various to the point it was not safe to ride in traffic due to not knowing how the motorcycle would react to different throttle inputs. In order to fix the problem the throttle position sensor had to be replaced.”
NHTSA complaint #10149681, filed 2006-02, 14,000 miles“Tps causing stalling and erratic idle. Problem occurs more when bike is warm, off, then re-started. Have only had it stall once while riding. Happens more often as above.”
NHTSA complaint #10118772, filed 2005-05, 100 miles“Front drive shaft, chain sprocket ‘Nut/lock washer’ has came loose and fell off on the highway. Could have locked the chain around the wheel and cause a major crash, also could have severely damaged the engine casing. It damaged the rear swing arm and a piece piece near the stater. I replaced the nut & locking washer tab, exact replacement only To have the same issue just I didn’t allow it to spin off since I was aware of this happening. I replaced the second one with a different style but same locking washer tab same issue it comes loose within 8 to 10miles. …”
