According to documents from The National Highway Traffic Safety Administration, the problem can occur if riders miss a gear while upshifting. It's possible that the following shift might put enough added strain on the drivetrain to move the rear axle. This can damage the left-side chain adjuster. If there's too much harm done to the part, then the chain could potentially slip off the bike, leaving the powerless bike more vulnerable to a crash.
To fix the problem, Suzuki dealers will "replace the left-side adjuster with an improved part" that will be heat-treated to be stronger. Scroll down to read the full recall report.

Suzuki Motor of America, Inc. (Suzuki) is recalling certain model year 2011-2014 GSX-R750 and 2009-2014 GSX-R1000 motorcycles. If a gear is missed while upshifting, the strain applied to the drive chain after the next shift may cause the rear axle to move, damaging the left-side drive chain adjuster.
If the drive chain adjuster gets damaged, the drive chain may come off, removing power to the rear wheel, and increasing the risk of a crash.
Suzuki will notify owners, and dealers will replace the left-side chain adjuster with an improved part. The recall is expected to begin on October 17, 2014. Owners may contact Suzuki customer service at 1-714-572-1490. Suzuki's numbers for this recall are 2A40, 2A41, 2A42 and 2A43.
