Over 4 years ago, Rivera Primo launched its new line of premium quality Left Side Drive & Right Side Drive Softail style six speed transmissions, with an industry first 2 year unlimited mileage replacement guarantee. These PowerDrive™ 6 transmissions have become a gear box to have in terms of reliability and smoothness. All transmissions have choice of finish (polished, chrome or black wrinkle), 32 tooth final drive pulley, close ratio 2.94:1 first gear; second gear 2.21; third gear 1.60, fourth gear 1.23; fifth gear 1.00, 0.860:1 overdrive sixth gear, & forged and back cut dogs for positive shifting.
With the release last year of Rivera's 4 to 6 speed conversion kit for 4 speed swing arm frames which includes a specially made 6 speed splined shaft transmission specifically for 4 speed swing arm frames, we put our PowerDrive™transmission line literally into overdrive!!.
