Kit 282cc MALOSSI Ø75,5mm, cylinder / piston, PIAGGIO VESPA, GTS, SUPERSPORT, HPE ... 300 computer unit (real 278cc)

High performance MALOSSI kit for VESPA 300 4T from 2019. you should know that as a base, the VESPA 300 4T from 2019 until 2021 (before euro 5) with its 63mm stroke and its 75mm bore, made in reality 278cc real! This kit with its diameter of 75.5mm, increases your displacement to 282cc real and above all, it allows to increase the compression ratio to 12.5: 1! Cooling, reinforcement ... Everything is improved on the kit!

Cylinder

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 a coupling tolerance of 0.05 mm
Recalculated and enlarged heat exchange surfaces

Piston

Extra compact three-segment
Material: special aluminum alloy with high silicon content with low thermal expansion with application of tin on the sliding walls
CNC machine tool machining
Lightened and reinforced
Enlarged heat exchange surfaces

Segments

Specials 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 ring made of special steel, chrome-plated

The box which is delivered to you is the FORCE MASTER 3. It makes it possible to modify the engine carthography in order to have a beautiful injection curve, a good AFR ratio of richness, and to limit the maximum engine speed to 1000rpm.
