Next, Yamaha opted for a novel separate-dog arrangement. Normally the gear dogs, the castellated sections that slide sideways into an adjacent gear to lock a particular gear to the shaft, are part of the gears themselves. But Yamaha's solution, separating the sliding dogs from the gears, is more compact. In addition to adding a new gear, Yamaha revised pretty much every gear ratio. First and second are slightly taller (transmission ratios only), third is about the same, fourth and fifth are slightly shorter than before, and sixth is some 9 percent taller than the old fifth. In addition, Yamaha raised the final-drive gearing marginally—2.693:1 versus 2.773:1. The result is a top gear 10 percent taller than before, better spacing for performance in the top three gears, and not-really-noticeable taller initial ratios.
