Earlier this month, we reported on a recall for Ohlins TTX36-series rear shocks. The initial recall specifically referred to TTX GP, TTX RT and TTX36 MKII shocks sold as aftermarket accessories, but new recalls announced in Australia and Canada suggests that Ohlins TTX36 shocks installed as stock components on some motorcycles may also be affected. The first motorcycle to be included is the 2015 Yamaha YZF-R1M.
The higher-spec version of the R1 comes standard with electronically-controlled suspension from Ohlins, and based on the description by Transport Canada and the Australian Competition and Consumer Commission, the recall is for the same problem affecting the aftermarket shocks.
“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,” reads the Canadian recall.
Yamaha dealers will inspect R1Ms and, if necessary, replace the rear shock with a correctly-manufactured shock. The Canadian recall affects 62 motorcycles. No figures were provided with the Australian recall.
As of this writing, the National Highway Traffic Safety Administration has yet to announce a similar recall for the U.S., but we may see one soon for the R1M as well as any other models that come standard with the defective shocks.
