Naraku Performance QMB139 & Piaggio Torque Spring Base
- Overall Height: 30mm
- Does not include spring!
Naraku Performance torque spring base for 50cc QMB139 engines, Aprilia, Honda, Piaggio, Derbi, Kymco, and much more!
Naraku Torque Spring Base allows for smoother torque spring action through the use of ball bearings. This allows the spring to pivot and turn free rather than binding up.
Please note: spring shown in pictures for reference only, it is not included. Please see related items for performance torque springs. High Temp grease should be used on the ball bearings.
