Primo's Brute IV Extreme Touring Open Belt Drive is just a measly 2" wide, but boy can it hold the power. The special 2" wide 8mm pitch Kevlar corded belt included with this kit was specifically designed to hold in excess of 150 HP. The drive's electric start feature utilizes a 66 tooth ring gear for maximum torsional longevity. It also features a modular heel toe shifter linkage support so you don't have to figure out how to run your linkage as on other drives. Imagine, no more primary oil changes, no more leaking gaskets; almost maintenance free for your bagger. And then there's the super light pull on the included world famous Pro Clutch, yet it holds 120+ HP. And those that have more horsepower can add the TPP Variable Pressure Clutch Assist that works like a mini lock up, holds over 200+ HP and still has a super light pull.
