I still wanted to lower the final-drive gearing to make the torque easier to access at lower revs, improving rideability on the street. If Renthal sprockets are good enough for Blake Young's Yoshimura Suzuki GSX-R, they're good enough for ours, so I ordered up a set. I went one-down/two-up in order rip through the revs a little quicker (16-tooth front, $34.95/47-tooth rear, $72.95, www.renthal.com). Dividends were paid immediately around town, while fuel mileage barely suffered on the street, only adding about 800 rpm at highway-cruising speeds. Take note, however: the taller rear sprocket did cause the chain to rub on the stock chain guard, necessitating its removal. And, of course, the non-stock gearing will throw off the speedo.
