It hasn’t been long since deliveries of the all-new Yamaha R1 and R1M started and there is a problem already. According to a statement issued by Transport Canada and the Australian Competition and Consumer Commission the rear Ohlins shock on the R1M motorcycle could come apart during use.
The statement further explains that the rear shock might have been manufactured with a certain defect. The piston rod nut might have been tightened before the piston had the correct full metal-to-metal contact. This would result in the nut loosening, further preventing the proper functioning of the rear suspension action, that could result in a crash.
The Ohlins suspensions that are affected by this issue are both stock and aftermarket TTX36, TTX GP, TTX RT and TTX36 MKII units that were manufactured between November 9, 2013 and February 20, 2015.
Yamaha has informed it’s dealers in both the countries and are in the process of informing owners to bring their vehicles to the nearest dealership for inspection. If necessary, the dealers would change the rear shock unit free of charge.
The 2015 Yamaha R1M was first shown at the 2014 EICMA show and deliveries of the motorcycle began as recently as late-March 2015.
