After extensive testing with some of the fastest riders in the country Nihilo Concepts has developed a much needed Heavy Duty Clutch Spring kit for the KTM 85/105 and 2014-2017 Husky TC 85. This new design helps eliminate clutch slippage under heavy load and hard acceleration while keeping lever pull at stock feel. When fanning the clutch the Nihilo springs keep clutch action tight. These new springs are a must have for the serious racer! Add the Nihilo Heavy Duty Clutch spring kit to your Modified motor for optimum clutch operation. Same springs used by top KTM riders all over the country: Jordan Bailey, Brock Papi, Challen Tennant, Enzo Lopes, Mitchell Falk, Ciaran Naran, Conner Mullenix, and Parker Mashburn. Fitment: 2002-2017 KTM 85/105 SX/XC 2014-2017 Husqvarna TC 85
