Derbi senda 50R cylinder assembly, raspberry 70cc. 

In the video I show how to install the popular raspberry to Derbi senda. In another video you can see how to prepare it, because after purchase it is only theoretically ready for installation. After the change, no modifications, no adjustments, the same carburetor, the same exhaust, it is very good to feel that the power is greater. The speed is the same as at 50 because the gear ratios have not changed and at 50 it also reaches the maximum rpm.
