These engine come complete with flywheel/ stator assemblies which are compatible with virtually all Chinese scooters but for some scooters e.g. Peugeot V-Clic you may need to use your old flywheel and stator.

  • Q. Hello me again. Is this item is restricted and whats the top speed? Thanks
  • A.

    Hi, the engines are not restricted in any way however your bike may have a restricted cdi (ignition) system as standard. If this was the case you would need to swap the cdi for an unrestricted one. So basically if your bike is currently unrestricted it still will be after fitting this engine.
    Top speed on a 50cc 4-stroke moped will be about 38mph. There are not really any 4-stroke 50cc mopeds which will exceed this without significant modification despite what other manufacturers may claim.
