NHTSA recall 15V221000
Suspension · Yamaha Motor Corporation, USA
Details
What's wrong: The affected motorcycles may have been built with an improperly manufactured rear shock absorber. The nut on the damper rod for these shock absorbers may loosen, resulting in a loss of damping and the possible disassembling of the shock.
Why it matters: If the damper rod nut loosens, shock absorber performance would be affected, possibly causing a loss of vehicle control and increasing the risk of a crash.
The fix: Yamaha will notify owners, and dealers will inspect the motorcycles and replace any affected rear shock absorbers, free of charge. The recall began on April 29, 2015.
