While stopped at intersection, I was attempting to accelerate from 1st gear to 2nd gear had a total lose of power. Had to shift into 3rd gear to continue thru the traffic light intersection. When trying to up shift had lose of power in 4th gear also and had to shift into 5th to maintain speed. After removing clutch case cover found a broken brass spring in bottom of the crank. After reading the maintenance manual it appeared to be the gear selector spring, was verified by triumph tech that it was. Now I have to turn bike in to a triumph service center to replace a $4 spring, which require removal of the engine to replace. The clutch system I see as a trend elevating the risk for riders/drivers.

Tl* the contact owns a 2008 triumph rocket iii touring motorcycle. While driving approximately 65 MPH and attempting to accelerate to pass other vehicles in the left lane, the motorcycle failed to accelerate and suddenly stalled. The motorcycle was towed to the dealer who diagnosed that the plastic twist grip, which houses the steel cable to the accelerator throttle, had sheared off. The vehicle was repaired and the failure was remedied. The manufacturer was notified of the failure. Approximately two years later, the failure recurred while riding approximately 45 MPH and attempting to accelerate to pass other vehicles. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the second occurrence. The VIN was not available. The failure mileage was 20,000.

Failure of clutch actuator assembly on 2008 model triumph rocket iii touring motorcycle. 1. The events leading up to the failure - new bike, 5000kms, loud noise coming from clutch housing. Requested supplier to examine this. They concluded there was nothing wrong. I took it home and dismantled the clutch myself to find that the case hardening on the clutch actuator rod had failed and the needle roller bearings had dug into the shaft causing this noise. The shaft was very close to failing and the needle rollers were damaged. I set photographs of the damage to the bike supplier (bikebiz) and they agreed to fix it. I took 10 weeks to get any action from triumph to provide the parts. I have no faith in the replacement parts and will now get rid of the bike. Engine number: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Clutch failure on my motorcycle, which was caused by a broken internal part (lifter shaft). My motorcycle has been in the shop since that date(5 weeks now), awaiting part replacement. In my opinion this is a poorly designed part. When it brakes complete failure of clutch operation is the result. It can brake at any speed, without warning. Clutch failure can lead to serious consequences while riding a motorcycle.
