With its patent-pending self-engaged twist dial, ProTaper's revolutionary Self-Engaged Launch Assist (SELA) can be easily set without any assistance, giving riders the freedom to practice starts and line up for races by themselves. During start, SELA makes it possible to temporarily compress the motorcycle's front suspension, reducing its tendency to wheelie under acceleration. This optimizes rear wheel traction, allowing the rider to be more aggressive with the throttle and launch down the start straight with greater control. Dual-hinged receiver ring makes for quick and convenient installation without removing the front wheel or fork. Unique, single-SKU design allows for installation on most full-size, late-model motocross bikes.This Part Fits: Year Make Model Submodel 2015-2025 Honda CRF250R Base 2012-2025 Honda CRF450R Base 2019-2025 Honda CRF450RWE Base 2015-2025 Husqvarna FC250 Base 2015-2025 Husqvarna FC350 Base 2015-2025 Husqvarna FC450 Base 2018-2020,2022-2023 Husqvarna FC450 Rockstar Edition Base 2015-2025 Husqvarna TC125 Base 2015-2025 Husqvarna TC250 Base 2019-2022 Kawasaki KX250 Base 2015-2018 Kawasaki KX250F Base 2019-2022 Kawasaki KX450 Base 2015-2018 Kawasaki KX450F Base 2015-2026 KTM 125 SX Base 2015-2022,2025 KTM 150 SX Base 2015-2026 KTM 250 SX Base 2015-2026 KTM 250 SX-F Base 2015-2016,2022,2024-2025 KTM 250 SX-F Factory Edition Base 2015-2026 KTM 350 SX-F Base 2015-2026 KTM 450 SX-F Base 2014-2025 KTM 450 SX-F Factory Edition Base 2013-2026 Suzuki RMZ250 Base 2013-2026 Suzuki RMZ450 Base 2015-2023 Yamaha YZ125 Base 2015-2023 Yamaha YZ250 Base 2010-2023 Yamaha YZ250F Base 2010-2023 Yamaha YZ450F Base
