Suzuki Motor Corporation (SMC) and the National Highway Traffic Safety Administration (NHTSA) have announced the recall campaign number 14V629000 which is aimed at around 23,073 Suzuki sport motorcycles.
This time, the Gixxer customers may experience a transmission problem which might leave them without power at the rear wheel, seriously increasing the risk of a crash. All in all, this issue might appear if a rider does not upshift correctly, and the gearbox remains in a neutral state, but with the engine revving at a high speed.
Most riders, facing this situation would be tempted to recover from the missed shift immediately, without disengaging the clutch. Should this occur, putting the bike in gear will excert a hughe amount of torque to the drive sprocket, in turn causing excessive strain in the upper part of the drive chain.
The left side of the rear axle might move forward and damage the left chain drive adjuster. In more severe cases, the chain may come off altogether and thus power from the engine would no longer be transmitted to the rear wheel, potentially causing loss of control and a crash.
Suzuki dealers will replace the left side chain adjuster with a new, stronger part which will no longer be damaged under such stress. The new part has been heat-treated to make it stronger.
Two Suzuki series are affected by this problem. The 2011-2014 model year GSX-R750 and 2009-2014 model year GSX-R1000 motorcycles, and the customers of these bikes are advised not to use them until the repair is performed by a Suzuki authorized technician. The repair will be free of charge, Suzuki informs us.

The drive chain adjuster has insufficient strength to withstand the extreme tension
After an investigation, Suzuki has determined that the drive chain adjuster is not strong enough to withstand the extreme forces occurring in the aforementioned scenario. If the rear axle becomes misaligned, certain abnormal sounds could be heard, indicating that there is a problem in the final drive department.Suzuki dealers will replace the left side chain adjuster with a new, stronger part which will no longer be damaged under such stress. The new part has been heat-treated to make it stronger.
