Description


The Vespa PX 80 was a special to the german market. This racing crank shaft with heavy altered inlet timings, raises the power, especially in conjunction with cylinder kits like the Malossi 139, DR 135.

Due to the raised inlet timings the engine tends to splutter in the lower revs. We suggest to use a reed valve intake to get a smooth carburation over the whole rev range.

The new designed and flowed crank webs and the lower silver cage bearing show the quality of this Italian manufactured product by Nuoava Mazzuchelli.Delivery with upper cage bearing. Order crank bearings and seals separately. Fitting tools and complete revision-kits are available in the shop as well.

Check and set up of the carb jetting after installation !

Stroke 48mm, piston pin Ø 15mm , connecting rod length 105mm for all PX 80 engines (V8X1M)
