TUNING SPORT – high-performance Product description
Get to the max! with the
112cc
high flyer. The answer from
MALOSSI
for all capacity fetishists.
Higher compression than the POLINI kit,
MALOSSI
breaks the barriers with a compression of 12.5:1. High octane petrol gets it moving and propels this short stroke cylinder from racing start to racing start.
MALOSSI’s
equipped this
power cylinder
with it’s own cylinder head layout for an effective and optimal combustion. In any case, the motor should be equipped with a race crankshaft. The Golden Rule applies here: clean ignition and ccarburettor tuning is the guarantee for power punching short distances. The original transmission should be replaced with a taller primary drive. For better heat dispersion, we recommend painting the surface black. A matt black surface radiates heat more intensively- much better than a light colored or polished surface.
Conclusion:
the ideal cylinder for city traffic, hefty torque, loves rpm’s, extensive product range. The maximum displacement in the < 125ccm class. If you dream of drag racing with a Porsche or a Vespa vacation in Italy, move on up to the 130 ccm class.

3.00 to 2.86 transmission, reinforced clutch or PK-XL clutch are a must, racing shaft and carburettor size 19 – 24mm recommended. A “must have” – the SITO Banane, better the POLINI racing exhaust. A HP4 or a
