You've all been waiting for it… The big kit that will finally make your 125cc YAMAHA N-MAX or MBK OCITO 155/150 maxi scooters roar! Here it is, the famous Ø63mm kit which is also delivered with the multi-curve electronic calculator As usual MALOSSI has made a powerful, solid, torquey and very high-end kit. This little monster will project your displacement from 125cc to 182.58cc real extreme performance. MALOSSI has for this thermal group found the perfect race / diameter ratio, this cylinder will be easily supported by your original crankshaft. It is already running in competition and in endurance, so that means it has been tested... Force Master 2 is the electronic box that allows you to change the injection to adapt perfectly to the new Malossi 4t thermal group. This box has been programmed with different programs in order to be coupled perfectly to your vehicle, whatever its configuration! With this box 4 curves are offered to you…
- curve 1: best performance with the original cylinder
- curve 2: Malossi cylinder and original exhaust
- curve 3: Malossi cylinder and modified exhaust
- curve 4: electronic unit excluded
Let's see now rather how MALOSSI did to increase the performance of the high engine, it obviously did not stop increasing the diameter of the piston cylinder! Here are the technical characteristics of the kit:
Cylinder
Bore: Ø 63mm; Stroke: 58.6mm;
Displacement: 182.58; Compression ratio: 10.6:1.
• Material: primary aluminum alloy with high silicon content
quenched and tempered, cylinder liner with application of carbon carbides
silicon in a galvanic nickel matrix and cross-smoothing by
two diamond passes, 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 with three segments
• Material: special aluminum alloy with a high silicon content a
low thermal expansion with application of tin on the walls of
sliding
• Machining by CNC machine tools
• Lightened and strengthened
• Enlarged heat exchange surfaces
Segments
• Specials with high sliding and very high mechanical resistance
• 1st compression segment in nitrided and chromed steel
• 2nd segment in special cast iron
• Three-piece scraper ring made of special steel, chrome-plated
With this kit you are therefore in position of an ultra robust, powerful and safe equipment! No more soft accelerations, limited top speeds… Disappointing pick-ups! Attention, this kit is still not to be put in just anyone's hands... Informed pilot!
