The NARAKU HS-High Speed vario is an evolution of one of the most successful varios for 4-stroke vehicles. The roller ramp design results in a maximum of torque and top speed. The key to a good variator is its ability to keep the engine at constantly high rpm over a wide range of vehicle speeds, which makes the HS variator one of the best ones for 4-stroke engines. Even other renowned manufacturers find this a hard nut to crack.

Another advantage for unexperienced tuners is the fact that the NARAKU HS variators come already pre-adjusted.

This version comes ready to install for all standard 50cc engines without modifications. Using a stronger torque spring is not recommendable for 50cc engines without further tuning. However, if other tuning parts are used, a new setup may be required.

Included in the delivery are the complete variator, open variator bushing with speed control washer as well as a set of variator rollers (16 x 13mm) suitable for 50cc original cylinders.
Attention: The variator bushing is under the plastic packaging!
