103 SPX/RCX (ref: 216548)

Like the ER3, the ER2 is an oversize variator. It can be differenciated from the ER3 by its visual aspect and its roller functioning. Its ingenious dismounting small column guiding system offers easy adjustment without removal. The roller system offers precise setting and a large choice. 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 ER2 variator is nikasil-treated to improve durability.
