MBK 51 KICK (CLUTCH FUNCTION) (ref: 292536)

The ER3 is an oversize variator coming from competition. It works with two variator weights. Its frontage setting system allows for adjusting without dismounting. It's a considerable time gain. Associated to a ER1 engine spring, it will provide a higher and linear engine-speed increase. The ER2 and ER3 are available in direct inlet 103/SPX/RCX/MVL and 51, and also with clutch fixing for 103 MVL and with clutch function by a needle cage insert for the kickstart 51. The ER3 variator is nikasil-treated to improve durability. DOPPLER recommends to use its belt.
