Drive face boss / vario bushing Naraku tuning

Modified variator sleeve with custom thrust washer for Kymco KXR / MXU 250/300, 300 Maxxer. The length of the sleeve and the disc drive means the belt is positioned more to the outside. This means an increase in top speed of around 9mph. Optimal acceleration is achieved with 20g variator weights (not included!). In conjunction with the Malossi Multivar variator, the excellent acceleration from the variator comes from the significant increase in speed of the sleeve. This makes the sleeve the best possible tuning option for the drive train. The NARAKU variator sleeve replaces the original or the Malossi Multivar. Attention! Please refer to the installation instructions. This can be downloaded above. There is a difference between KXR / MAXXER and MXU models.
