DOPPLER ER1 variator with 100mm range clutch for Peugeot 103 SPX, RCX, MVX & CLIP

The DOPPLER ER1 variator is the direct competitor of the POLINI SPEED CONTROL and MALOSSI MULTIVAR, it is a small competition variator which will make you preserve your fixed cheek and your original range.



For your Peugeot 103 SPX, MVX, CLIP and RCX this variator will offer a more longitudinal rise, more precise, more acceleration and a more thrust range of a few millimeters. It is in a 6-roller system like scooters.



It is a very good variator, robust, precise, which offers excellent acceleration in addition to being ultra light. It comes with 2 sets of rollers in order to be able to fine-tune your settings, nothing requires you to install a competition mainspring although this is obviously more efficient.
