Doppler ER2 variator
Classic roller variator, as installed in most mopeds and scooters.Doppler ER3 variator
Doppler variator with tilting weights – different from rollers and even more efficient.
Modern technology for vintage mopeds
In our shop, Doppler variators are available for classic French mopeds. For Peugeot 103 and MBK 51, two models are offered, each for versions with or without clutch: the ER2 with rollers and the ER3 with weights.
Both versions are high-quality and very efficient products (suitable for use with sport and racing cylinders). According to Doppler, the ER3 offers a clear advantage: tuning can be done without disassembly, which is especially practical on the racetrack.
The variators are designed with a larger diameter, allowing for a noticeable increase in top speed.
