Yamaha YZF-R1: Suspension
Affects Yamaha YZF-R1 · 2015 — about 62 vehicles.
The hazard
On certain motorcycles, the rear shock absorber may not have been manufactured correctly. The piston rod nut may have been tightened before the piston had the correct full metal-to-metal contact. This could result in the nut loosening, which would prevent proper rear suspension action, and could cause poor handling that may result in a crash causing injury and/or property damage. Correction: Dealers will replace the rear shock absorber with a correctly manufactured one.
