Taller Gearing: I felt that Yamaha missed the mark on the overall gearing as the bike spins 5,400 rpm at an indicated 80 mph with the stock 16/45 sprocket combination. Why gear this torquey triple so low? Perhaps it's our love of acceleration that dictates gearing, but out on the open road I would like an engine that just loafs along sipping fuel at a less-busy point on the tach. How about five close-ratio speeds and a really tall overdrive sixth? How about seven speeds? Eight? Those choices were out of my hands so I called Driven and ordered up a 17-tooth front sprocket and a 43-tooth rear, choices that kept the stock chain length for convenience because I'll swap back and forth depending upon the day's activities. All the charts regarding gearing choices and chain lengths are on the Driven website and customer support was excellent. The gain was 10 mph at the same engine speed, so 5,400 was now 90 mph, with 80 mph happening at 4,800 rpm. Quieter, less hectic, better fuel mileage.
