new new new doppler OPEN clutch pulley for MBK 51 aka motobecane AV7 & AV10 mopeds.

this is a completely new design from the ER2 clutch pulley as it uses a multi plate dry clutch driven by centrifugal weights. essentially, it's a mini ducati dry clutch and ya tune your clutch stall by using roller weights. due to the dry plate design, it's super compact! insane!!

another cool feature is that the pedal shaft has dual cotter pin grooves on one end, meaning you don't have to grind anything to run traditional pedal arms.

Significant improvement over classic and ER-86	March 5, 2025
taco eater : Ian Templeton from Shoreline, WA United States

I have been running this on my 50V for the last few months and so far it is pretty great. Much less vibration than either of the other two doppler clutch pulleys. I also really like it's more compact profile. The spring loaded pin for starting is a little annoying with gloves on, and seems a little fragile. The pulley needs to be fully disassembled to change the weights, which is also not the easiest.
