Name Polini Crankcase P.R.E. 100cc Piaggio Zip SP LC Item No. P050.0952 Brand Polini
Tuning specialists Polini introduce their outstanding P.R.E. racing kit (Polini Racing Engine), and this is the basis for all the high-end components: the Polini Crankcase P.R.E. 100cc Piaggio. The crankcase is based on the crankcase layout for short Piaggio engines which is the engine mostly used at the Polini Cup. Even though the base is quite similar, the details and the remaining engine components are quite different.
- increased crankcase volume
- innovative support to optimize cylinder to exhaust alignment
- made from light alloy
- reinforced bearing seats
- improved torsional resistance
The P.R.E. crankcase is a high-end piece of equipment, designed for the race track and for dedicated tuners. As such, it is customizable - you can add different tuning parts such as a lighter / heavier flywheel. It also offers the possibility to use different brake systems, both in combination with the Polini Torsen WD swingarm: you can either run it with a standard drum brake and original rim or you can switch to disc brake if you upgrade your scooter with the new P.R.E. engine mount plus Polini rim + 2-piston caliper.
The crankcase is "empty", that means without bearings and oil seals (and any other engine components).
