NARAKU COMPLETE 139QMB AND KYMCO RACE VARIATOR KIT. The Naraku HS-High Speed vario is an evolution of one of the most successful variators 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 tuners without much experience is the fact that the Naraku HS variators come already pre-adjusted.

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.
