For everyone's pleasure... Here is the big kit that will give some punch to your 50cc 4-stroke scooter! The Ø44mm 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 concentrate of technology will project your displacement from 50cc to 66.30cc real, in other words performance at the rendezvous! This thermal unit has the perfect stroke / diameter ratio, this cylinder will be easily supported by your original crankshaft.
The electronic box or FO RC E MASTER 2 will allow you to change the injection to adapt perfectly to the new MALOSSI 4-stroke thermal group. This ECU has been programmed with different programs in order to be perfectly coupled to your vehicle whatever its configuration! With this box 3 curves are offered to you...
-Curve 1: Best performance with the original cylinder. -Curve 2: MALOSSI cylinder and original muffler. -Curve 3: MALOSSI cylinder and modified exhaust.
Let's see how MALOSSI has done to increase the performance of the high engine, it is obviously not stopped to simply increase the diameter of the piston cylinder! Here are the technical characteristics of the kit (description MALOSSI ):
-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 smoothing crossed by two passages of diamonds, 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 has three segments -Material: special aluminum alloy with high silicon content with low thermal expansion with application of tin on the sliding walls - 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 chromed steel -II 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!
