MAIN FEATURES OF THE NEW VERSION:

High compression head

Decompressor

0.7 mm cylindrical squish

8.00 mm Race Camshaft

Close change with first long and second short

Variable advance ignition

Keeping in mind that the standard versions have a 56mm dome head and a 1.6mm squish cylinder (which involves a compression ratio of 8.9: 1); it is possible to visibly appreciate the best performances of the NEW VERSION, in fact the ZS155 gpx 2.0 engine is fitted as standard with the small 53.0 mm dome head and a cylinder with squish reduced to 0.7mm; this solution brings the compression close to the ratio of 11: 1 ensuring greater power, torque and readiness of the engine in increasing revs. It also adopts a race camshaft with increased lift, from 8.00mm (compared to 6.7mm of the standard camshafts), the decompressor integrated in the head and a functional 6-disc clutch, strong, precise and very soft when activated. The equipment is completed by the digital ignition with variable advance and the gearbox with close spacing (first long and second short): 1 = 2.62 2 = 1.71 3 = 1.353 4 = 1.05

against standard spacings: 1 = 3.272 2 = 1.937 3 = 1.353 4 = 1.05
