722545 Fits 1994 Thru 2005 Dyna and Softail

The Rivera Primo Brute III Extreme is a heavy-duty primary drive system built specifically for high-horsepower Dyna and Softail models. This kit features a proprietary 11mm, 1 3/4-inch "dense pack" Kevlar polychain belt that is virtually indestructible, designed to withstand the extreme shock loads generated by large-displacement, highly modified V-Twin engines. A major advantage of the Brute III Extreme is its ability to fit within your stock inner and outer primary covers, maintaining a factory appearance while delivering race-ready durability. Whether you are using a stock-style starter ring gear or Primo’s 84-tooth version, this system represents the pinnacle of primary drive technology for riders who demand maximum strength and reliability.
