You've all been waiting for it... The big kit that will finally make your 125cc YAMAHA N-MAX or MBK OCITO 125 maxi scooters roar! Here it is, the famous Ø63mm kit which is also delivered with the multi-curve electronic computer 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 found the perfect stroke/diameter ratio for this thermal unit, this cylinder will be easily supported by your original crankshaft. It already runs in competition and in endurance, so it is tested... Force Master 2 is the electronic unit which allows you to change the injection to adapt perfectly to the new 4t Malossi thermal group. This box has been programmed with different programs in order to be perfectly coupled to your vehicle, whatever its configuration! With this case 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 pipe - curve 4: electronic box excluded
Let's now see how MALOSSI did to increase the performance of the high engine, they obviously did not stop at increasing the diameter of the piston cylinder! Here are the technical characteristics of the kit:
Cylinder
Bore: Ø 63 mm; Stroke: 58.6 mm; Displacement: 182.58; Compression ratio: 10.6:1. • Material: primary aluminum alloy with high silicon content quenched and tempered, cylinder liner with application of carbides silicon in a galvanic nickel matrix and cross-smoothing by two diamond passes, with very strict tolerances • Machining: by high-precision CN 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 • Machining by CNC machine tools • Lightened and reinforced • Enlarged heat exchange surfaces
Segments
• Specials with high sliding and very high mechanical resistance • I° compression segment in nitrided and chrome-plated steel • II° special cast iron segment • Three-piece wiper ring made of special steel, chrome-plated
With this kit you will be able to secure an ultra-robust, powerful and safe piece of equipment! Gone are the slow accelerations, the restricted top speeds… The disappointing restarts! Be careful, this kit should not be put into just anyone's hands... Driver beware!
An electronic unit which allows you to adjust your injection with 4 different programs. Guaranteed performance gain and increased engine reliability EURO 3 before 2017 only!
