MEC EUR 60/110: Lambretta racing shaft with scope for tuning
This is the entry into the world of Lambretta racing shafts.
The shaft is based on very good Italian crank webs. The shaft is assembled with European quality bearings, making this shaft a faithful companion even in high-revving engines. This shaft has a stroke of 60 mm due to the connecting rod journals being moved further outwards. Thanks to the 110 mm connecting rod, there is plenty of scope for changing the timing. The cylinder can be lowered quite easily to reduce excessively long overcurrent times. Simply use a spacer less than 3 mm thick to compensate for the longer connecting rod.
Depending on the manufacturing tolerances, it may be necessary to grind the connecting rod or the engine housing.
