The 2014 Aprilia Shiver 750 has 2 recalls, both concerning a sprocket fastening screw that can loosen on the output gear shaft and cause the rear wheel to lock up suddenly, raising the risk of a crash.
When the screw works loose, the drive sprocket loses its secure connection to the shaft, and the resulting wheel lockup can happen with little warning, leaving the rider with limited ability to control the motorcycle.
