Dr. Pulley HiT Clutch for Minarelli and Yamaha 2-Stroke Engines
The Dr. Pulley HiT Clutch is built for racing use on Minarelli and Yamaha 2-stroke 50cc engines. It cuts down on transmission lag and helps the bike deliver power more quickly. It is also one of the Minarelli 50cc / Yamaha jog scooter parts that can noticeably sharpen acceleration. The 50-degree version is aimed at modified engines and is meant to engage quickly at higher RPMs.
High-Torque Lock-Up Mechanism
The clutch uses specially tuned 50-degree pillow springs, which keep it disengaged until the engine reaches its peak range, allowing for strong launches. The patented HiT lock-up design applies more pressure to the clutch bell under load, which helps prevent slipping and the overheating that often happens in racing. The 105mm clutch bell has oversized cooling vents to keep friction steady for more dependable performance during hard use.
Customization Options
The HiT Clutch comes with a pro-tuning kit that includes several sets of pillow and clutch springs, so you can change the engagement to suit your particular performance setup. This makes it easier to tune the bike to match your riding style and needs.
