130cc Top end kit for vintage Vespa Smallframe by DR. This will provide more bottom end power with a strong increase in exceleration over a stock cylinder. A good combination for even more power is a Proma pipe and a 19/19 carb.
*This is a performance part and as such requires setup during installation like, setting ring gap, chamfering ports, squish check, proper jetting, timing, break in periods, and often other components to be replaced to become reliable. Manufacturers label these as race parts and do not warranty race parts except when a part is defective before installation.*
