You've waited for all ... The big kit that will finally roar your maxi 125cc scooters YAMAHA X-MAX, YAMAHA X-CITY, MBK CITYLINER & MBK SKYCRUISER! Here it is, the famous kit Ø63mm which is also delivered with the electronic multi-curve calculator As usual MALOSSI has made a powerful kit, solid, torquey and very high-end. This little monster projected your 125cc engine to 182.58cc real extreme performance. MALOSSI has for this thermal group found the perfect ratio race / diameter, this cylinder serras without problem supported by your crankshaft of origin. It is already running in competition and endurance is therefore to say if it is tested ... Force Master 2 is the electronic box that allows to change the injection to fit perfectly to the new 4t Malossi thermal unit. This box has been programmed with different programs to be perfectly matched to your vehicle, whatever its configuration! With these boxes 4 curves are offered to you ...
- curve 1: best performances with the original cylinder
- Curve 2: Malossi cylinder and original muffler
- curve 3: Malossi cylinder and modified exhaust
- curve 4: excl.
Let's see instead how MALOSSI did to increase the performance of the high engine, it did not stop of course increased the diameter of the piston cylinder! Here are the technical characteristics of the kit:
Cylinder
Bore: Ø 63 mm; Stroke: 58.6 mm;
Cylinder capacity: 182.58; Compression Ratio: 10.6: 1.
• Material: primary aluminum alloy with high silicon content
tempered and tempered, cylinder liner with carbide application
silicon in a galvanic nickel matrix and crossed smoothing by
two diamond passages, with very strict tolerances
• Machining: using high precision CNC machine tools
• Cylinder-piston couplings with coupling tolerance of 0.05
mm
• Heat exchange surfaces recalculated and enlarged
Piston
• Extra compact with three segments
• Material: special aluminum alloy with high silicon content
low thermal expansion with application of tin on the walls of
sliding
• Machine tool machining at CN
• Lightened and reinforced
• Increased heat exchange surfaces
segments
• High sliding specials and very high mechanical resistance
• I ° segment compression in nitrided steel and chromed
• II ° special cast iron segment
• Three-piece scraper ring in special steel, chromed
With this kit you will be in the position of an ultra robust, powerful and safe! No more mole acceleration, slower spike speeds ... The disappointing recovery! Attention, this kit is still not put in any hands ... Driver warned!
