- Impact & Wear Resistance: The reinforced axle body is built to withstand high torsional stress, preventing bending or snapping during aggressive starting or backfiring.
- Enhanced Performance: Features a high-tension return spring and smooth-sliding ratchets for a crisp, responsive feel and rapid return to the neutral position.
