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.
Cast iron / 57.5mm bore / 6 transfers / 111.66cc
Cast iron cylinder, stroke 43mm, 6 transfers, divided in each 2 side transfers and a large divided boostport, piston with 2 piston rings, large piston cutouts, 6mm exhaust studs, original MALOSSI cylinder head, head screws, small-end bearing included in delivery, compression 12.5:1, incl. gasket set.
Fits all Vespa 50/PK/XL/XL2 models except the PK automatic. The crankcase should be matched to fit the larger cylinder transfers.
SIP-TIP: 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 SIP Performance would'nt be a bad idea.
