Variator Naraku Performance, incl. weights (5.8g \/ 6.3g) and torque spring, GY6

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 tuners without much experience is the fact that the NARAKU HS variators come already pre-adjusted.

This version comes ready to install for all 47mm and 51mm NARAKU cylinder kits together with the supplied torque spring. 47mm kits should be used with 5.8g rollers and 51mm kits with 6.3g rollers. If additional tuning parts are used, a new set up may be required.

Included in the scope of supply are the complete variator, open variator bushing with speed control washer, a fitting torque spring and 2 sets of variator rollers (16 x 13mm) suitable for 47mm and 51mm cylinder kits.
