Kit 70cc Ø47,6mm ATHENA Racing mono segment aluminum scooter PIAGGIO Liquid (NRG, RUNNER ...)

With its single-piston flat-plated piston, compression ratios of 14: 1 and its high diagrams, here is the ATHENA RACING version for PIAGGIO / GILERA liquid-cooled motor scooter. This very high quality kit has a EUROCILINDRO nicasil treated aluminum cylinder, very robust. A reinforced plunger piston with a single segment to allow the highest speeds, a high compression head with a frustoconical chamber offering a compression ratio of 14: 1. The recommended squish is 0.70mm.

Use only SP98, a crankshaft reinforced with bearings with a set of C4, a carburetion in 21 to 28mm, a muffler racing, a racing variator and if possible, a variable advance ignition ...

Ultimately, it is a very powerful and robust kit to accompany and mount correctly! There is also a pro version with breech block!
