Dr. Pulley HiT Clutch for Minarelli / Yamaha 2T - 60°

Dr. Pulley HiT Clutch Setup for Minarelli and Yamaha 2-Stroke Engines

The Dr. Pulley HiT Clutch is built for Minarelli and Yamaha 2T scooters, aimed at sharpening throttle response and cutting down on drivetrain delay. It suits riders who want to upgrade their machine, and it is one of the Minarelli 50cc / Yamaha jog scooter parts worth a look if you run a high-compression setup or race your scooter.

Clutch Design

The HiT Clutch uses a patented internal wedge that tightens its grip on the clutch bell as engine RPM rises. Because of this, the clutch locks up firmly, with less slip and more of the engine's torque reaching the wheel. The 60-degree pillow springs are matched to 50cc through 70cc builds so that engagement happens inside the power band.

Heat Management and Tuning

The included high-ventilation clutch bell is designed to shed heat, which helps limit glazing and fading when riding hard. The kit is adjustable: it comes with three pillow spring types and six clutch spring options, so you can change when the clutch engages and locks up to suit your riding.
