Yamaha Motor USA issued a recall for several motorcycles — FJ-09, FZ-09, FZ6R, Super Ténéré, Super Ténéré ES, and YZF-R6 — that were manufactured between September 1, 2014 and November 17, 2014.
The cause of the recall, which affects 4,900 units, is an incorrectly manufactured shift cam segment stopper, which has a sharp edge instead on the inside of the bend, instead of a smooth radius.
Because of this, the stopper can crack and possibly fracture where the edge is sharp, which in turn would cause the transmission not to shift properly.
