Kit 50cc high engine Ø40,3mm MALOSSI MHR TEAM aluminum minarelli am6

Here is the kit 50cc MALOSSI MHR TEAM motorcycle engine 50cc gearbox MINARELLI AM6. This cylinder is a very good hyper racing kit, with its well-defined diagrams, its very worked channels, its compression ratio, its booster exhaust, its stud yoke, its piston mono-segment with high silicon content, chromed steel segment, ...

 

 

As usual MALOSSI MHR, the finish is irreproachable, each piece has been over-studied ... The cylinder has a treatment nykasil of the highest end of the market, the piston is a very high silicon content and mono extra end segment (0,80mm) hard chrome domed to allow higher speeds very little wear ... the cylinder head is a model has stud in bia part in order to improve the maximum cooling the combustion chamber is a frustoconical model polished finish.

 

 

You will tighten the breech block without the breech cover! This technique makes it possible to carry out an ever more precise clamping! Especially a cylinder head pad has machined finish, MALOSSI MHR reinforced studs, nuts MALOSSI MHR special reinforced. Obviously, this yoke pad has a lip and the cylinder also in order to be sure that the combustion chamber is always centered on the cylinder.

 

 

It allows a very large increase in power while maintaining excellent torque, all without having to modify its crankcases to align! A very high-end kit made of noble materials and designed with advanced studies!

 

 

This kit is for competition, it comes with reinforced studs, bolts, several base joints to make the squish ... You should know that all kits MALOSSI MHR are numbered as you can see. malossi kit 50cc MHR TEAM for minarelli AM6

 

 

Description MALOSSI MHR:

 

THERMAL GROUPS MHR decomposable cylinder head
The new MHR CULASSE DECOMPOSABLE thermal units are the natural evolution of the MHR MALOSSI line. Fruit of the research of its technicians, they are at the origin of the victories of the national and European official teams in the trophies cross and speed. Malossi is pleased to guarantee to all the drivers who will want to participate in the National and European Trophies, a product worthy of a quality and performances of very high level.

CYLINDER
- Material: special aluminum alloy with a high percentage of silicon and titanium, which guarantees a high degree of indeformability even at high temperatures.
- Heat treatment: special heat treatment of quenching and stabilization, which on one side gives the material a high tenacity and excellent rigidity, and on the other hand gives the mechanical and dimensional characteristics a consistency up to a temperature of 250 ° C.
- Machining for trimming: made on numerically controlled machining centers with tolerances of dimensions and shapes (cylindricity, rotundity, perpendicularity) very strict.
- Report on the internal surface: performed with transfer of silicon carbides on nickel matrix, treated with a thermal process that guarantees extremely high hardness (about 600 HVD, 1/5) with a very high resistance to wear.
- Internal machining of the cylinder: with special machines that allow to obtain a level of finish on the sliding walls with crossing roughness according to the angles established during the design phase (oiling).
- Exhaust diagrams and openings: studied and made specifically for the competition. The definition of the exhaust and opening diagrams has required considerable work by our technicians on the static engine test benches and on the competition tracks on which the trophy takes place.

PISTONS
- Materials: special alloy with a very high percentage of silicon, to guarantee a very good resistance to heat and a non-deformability to temperature variations.
- External coating: graphite transfer which guarantees a very low coefficient of friction.
- Structure: strengthened to withstand the stresses that must undergo a thermal group for competition at the highest levels, but at the same time great lightness to reduce the forces of inertia.

SEGMENT
Spheroidal cast iron segment with high mechanical strength with additions on the contact surface, hard chromium anti-wear rectified and ground.

CYLINDER HEAD
The new decomposable Malossi cylinder head has been specially designed to ensure the evacuation of the huge amount of heat that develops in a very high specific power engine, intended for competition.
It consists of a specially tempered and tempered high-silicon aluminum alloy yoke, attached directly to the cylinder liner which is covered over its entire outer surface by coolant, which provides a very large surface area. exchange. In addition, since it is free relative to the outer wall, it can follow the expansion of the cylinder.
The combustion chamber is entirely made with numerically controlled machines, to guarantee tolerances of size and shape to the nearest hundredth of a millimeter.
A lid completes the decomposable cylinder system, which closes the upper part of the cylinder, for better holding of the coolant.
The combustion chamber of this thermal group has been specifically studied both from the point of view of geometry and squish for use on the occasion of the Scooter Speed ​​Trophy and Scooter Cross Trophy.

 

In option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust light by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification. Allow a little extra time for this preparation!

 

Here are some pictures of the preparation:
