Heavy-Duty Cranking: RDLN 20-Sprag High Performance Starter Clutch

Stop struggling with "starter slip" on your big-bore build. The RDLN High Performance Starter Clutch 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 20-sprag "one-way" bearing design. 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.

Technical Performance Features

  • 20-Sprag Locking Mechanism: 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.
  • Optimized for High-Output Starters: Engineered to pair perfectly with High-Output Starter Motors (Part #1100-1447) for maximum reliability.
  • Reinforced Forged Housing: The 79mm outer diameter housing is heat-treated to resist expanding or cracking during high-torque starting cycles.
  • Complete Installation Kit: Includes the precision-ground needle bearing for a smooth, low-friction "freewheel" once the engine is running.

Comprehensive Fitment Guide

This starter clutch fits the "Large Format" GY6 engine series (125cc/150cc/170cc). It is a direct fit for 152QMI and 157QMJ-based engines found in:

Brand Compatible Models
Chinese Brands TaoTao, Wolf, Ice Bear, Jonway, Peace Sports, Puma, Bintelli, Vitacci, Roketa
Premium Brands Genuine Buddy 125/150/170i, Genuine Hooligan, Kymco Agility 125, SYM Fiddle/Symphony
Engine Codes 152QMI, 157QMJ, 161QMK, 1P61QMK, YN1P57QMJ, 1P52FMI

Technical Specifications

  • Outer Diameter: 79mm
  • Keyhole Diameter: 22mm
  • Sprag Count: 20 High-Tension Sprags
  • Included: Starter Clutch and Needle Bearing

Mechanic's Note: If you have installed a 170cc or larger Big Bore Kit, a standard starter clutch is your weakest link. To ensure a long life for this 20-sprag unit, always check your Starter Idle Gear for chipped teeth before installation. We highly recommend using Blue Loctite on the mounting bolts to prevent them from backing out inside the flywheel.
