Always more performance and more solidity ... Here is the high engine which will literally boost your 125cc maxi scooters APRILIA SR, GILERA NEXUS, PIAGGIO BEVERLY, PIAGGIO MP3 YOURBAN and VESPA GTS SUPER. The famous Ø75.5mm kit which is in no longer delivered with its high performance cylinder head, camshaft and the multi-curve electronic computer.
As usual MALOSSI has made a powerful, solid, torquey and very high-end kit. This little monster will increase your displacement from 125cc to actual 217.58cc of extreme performance.
MALOSSI has found the perfect stroke / diameter ratio for this thermal unit, this cylinder will be easily supported by your original crankshaft.
To shorten it! The large diameter cylinder increases the displacement! The piston offers more compression and less friction! The cylinder head also offers more compression, a better explosion, reworked ducts and large diameter valves with hard springs for better admission, better exhaust and that the high revs follow! The box takes care of freeing the towers to the maximum and reviewing the injection mapping ... The cylinder / piston / cylinder head assembly also offers better cooling!
It is already racing in competition and in endurance, that is to say if it has been tested… Force Master 2 is the electronic unit which allows the injection to be changed to adapt perfectly to the new Malossi 4T thermal unit. This unit has been programmed with different programs in order to be perfectly coupled to your vehicle whatever its configuration! With this box 4 curves are offered to you ...

MALOSSI technical description
Cylinder
-Bore Ø 75.5 mm.
- Stroke 48.6 mm.
-Cylinder capacity 217.58cc.
-Increased compression ratio.
-Material: primary aluminum alloy with a high content of quenched and tempered silicon, cylinder liner with application of silicon carbides in a galvanic nickel matrix and crossed smoothing by two diamond passages, with very strict tolerances.
-Machining: by high precision CNC machine tools.
-Cylinder-piston couplings with coupling tolerance of 0.05 mm -Recalculated and enlarged heat exchange surfaces.
Piston
-Extra compact three-segment.
-Material: special aluminum alloy with a high silicon content with low thermal expansion with application of tin on the sliding walls.
-Machine machining
-Tools at CN
-Lightened and reinforced.-Enlarged heat exchange surfaces.
Segments
-Special with high sliding and very high mechanical resistance.
-I ° compression segment in nitrided and chromed steel.
-II ° segment in special cast iron.
-Three-piece scraper segment in special chrome-plated steel.
Cylinder head V4 HEAD
- Head in primary aluminum alloy cast by gravity, improved and sandblasted and worked on super precise CNC with tolerance to the thousandths.
-Valve guide with recalculated profile, obtained by powder sinterization process (steel, phosphorus, carbon, copper and manganese).
-Seat of the valves in steel alloy, cobalt, molybdenum and copper with special thermochemical treatment.
- Inlet valve increased to ø 25 in special steel bonded by thermochemical treatment.
-Exhaust valve increased to ø 22.2, material Nimonich 80 (alloy of nickel, chrome, titanium and aluminum).
- Intake and exhaust spring in pre-hardened and stabilized chromium-silicon steel with recalculated load good for the increase of engine power.
Power Cam
