The 102 is D.R.'s most powerful cylinder for the 1950 crankshaft. It is very well suited to build a fast touring engine. Necessary is then the longer primary (3.00) and a 19er carburetor.

Optionally in addition also a racing shaft with longer control times can be used. This will increase the power output in the upper rpm range, which is especially interesting in combination with a sports exhaust system. Beside the allround exhaust systems like the ET3 or SS 50/90 Banana, more sporty systems can be used. The LeoVinci Banana, for example, offers an official increase in performance, which of course has to be paid for with a sporty sound.
