Improved PX Crankcases in standard and sports versions.
A good 200 Crankcase is worth its weight in gold - so it was all the more painful when PIAGGIO discontinued production of the original spare parts in the mid-2010s. For the "Standard" and "Sport" Crankcases, a long-standing supplier close to the factory has created new molds and reproduces the PX engine cases in an extremely faithful manner.
- Quality like an original part
- Clean, smooth surface thanks to new mold
- Reinforcement at neuralgic points
- Plug & play also for long-stroke Crankshafts
There is rarely anything better than an original part - many improvements entail concessions in other areas. The "Standard" and "Sport" casings for PX Engines therefore treat the original design with particular care and only reinforce it where really necessary. In this way, the new casings meet the expectations that were previously placed on original casings.
Classic look, modern implementation
Thanks to brand new molds, the castings are also exceptionally clean: The surface is smooth, without heat cracks or splashes - visually very close to early Vespa-50 Crankcases or Rally-180 casings, for example. This high-quality appearance is continued in a look that is exactly true to the original: no allen screws that detract from the look, no tuning parts that are absolutely necessary for the function. All original Frame Parts can still be used.
Nevertheless, sensible improvements have been incorporated: The cylinder mount and crankcase have greater wall thicknesses so that there is sufficient material for milling and spindles. Cracks on the auxiliary shaft mount are now a thing of the past. The Disc Valve sealing surface is designed to be as large as possible. In the Sport version, the alternator side is spindled to 98.8 mm, so that in addition to the standard Crankshaft with 57 mm stroke, SIP Long Stroke Crankshafts with 60 and 62 mm also fit.
