The \u003cstrong\u003eRDLN High Performance Starter Clutch\u003c\/strong\u003e is a massive durability upgrade over the standard factory unit. While stock clutches rely on a weak 3-roller system, this RDLN unit features a \u003cstrong\u003e20-sprag \"one-way\" bearing design\u003c\/strong\u003e. This dramatically increases the surface contact area, allowing your starter motor to grip and turn over high-compression engines (150cc to 232cc) without the dreaded \"clanking\" or slipping of a failing bendix.\u003c\/p\u003e\u003ch3\u003eTechnical Performance Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20-Sprag Locking Mechanism:\u003c\/strong\u003e Distributes cranking torque across 20 points of contact rather than 3, providing a rock-solid engagement that won't slip under the load of high-compression kits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized for High-Output Starters:\u003c\/strong\u003e Engineered to pair perfectly with \u003cstrong\u003e\u003ca href=\"https:\/\/www.scooterworks.com\/products\/high-performance-starter-motor-gy6-125-150cc\"\u003eHigh-Output Starter Motors (Part #1100-1447)\u003c\/a\u003e\u003c\/strong\u003e for maximum reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Forged Housing:\u003c\/strong\u003e The 79mm outer diameter housing is heat-treated to resist expanding or cracking during high-torque starting cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Installation Kit:\u003c\/strong\u003e Includes the precision-ground needle bearing for a smooth, low-friction \"freewheel\" once the engine is running.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eComprehensive Fitment Guide\u003c\/h3\u003e\u003cp\u003eThis starter clutch fits the \"Large Format\" GY6 engine series (125cc\/150cc\/170cc).
