Intake Manifold MHR 21x24.5
List Price: $85.95
Our Price: $80.00
Sale Price: $72.00
You Save $13.95

Intake manifold conveys the air-fuel mixture to the engine by means of reed valve.

The total efficiency of an engine is calculated as the product of various partial efficiencies, such as:
- volumetric efficiency
- thermodynamic efficiency
- mechanical efficiency

Volumetric efficiency is the ratio between the quantity of fuel that can enter the combustion chamber and the displacement of the engine

Torque Driver
Our Price: $119.00

This component called Torque Driver for its specific function of determining the exact shifting moment, was calculated to give the vehicle the maximum possible acceleration in connection with the specific power of any single engine. The spiral's peculiar shape was studied to fix the RPMs on the point of maximum power.
It was expressly created to complete the development of boosted motors withour cylinders, variators and the special Malossi Kevlar Belts, allowing to fully exploit your vehicle's notable torque and power.
The new Malossi mobile driven split pulley ensures, on boosted vehicles,extraordinary acceleration and an extremely progressive and fluid torque output to the wheel. The tracks on the Malossi mobile driven split pulley were studied and designed on CAD-CAM systems and machined on CNC machinetools in order to guarantee total interchangeability with the original component and extremely high machining accuracy.
This new Malossi product is a concentrate of today's state-of-the-art technology.
Aluminum Cylinder Kit 47.6 pin 12 MHR Replica Modular Head
Our Price: $459.00

The new Malossi modular head has been specially created to guarantee elimination of the notable amount of heat that develops in an engine with a very high specific horsepower designed for racing.
It consists of a head in special hardened and tempered aluminium alloy with high silicon content that is fixed directly to the cylinder barrel. It is lapped over its entire outer surface by the coolant thus guaranteeing a very large heat-exchange surface. In addition, being unattached to the internal walls it is free to follow the expansion of the cylinder.
The combustion chamber is entirely manufactured using numerical control machines in order to ensure shape and size tolerances to within just one hundredth of a millimetre.
The modular head system is completed by a cover that closes off the upper part of the cylinder, thus guaranteeing that the coolant is fully sealed.
The geometry and cross-section of the combustion chamber for this cylinder unit have been specially designed for use in the Scooter Speed Trophy and Scooter Cross Trophy.

ELECTRONIC COILS
The continuous development of electronics in the automotive segment led Malossi to the creation and marketing of a complete line of electronic coils for scooters to be used on the street and for races which is at the highest level of technology.
Digital PVM Fixed Advance Ignition
Our Price: $249.00

Each electronic coil model was expressly studied for the scooter it will be fitted on, and this is the reason why after endless tests on the bench, on rollers and on the racing track an optimal start up map (fixed or variable) has been prepared in order to obtain the best performances of the vehicle. The Malossi electronic coils were designed to allow also a very easy assembling, since they are interchangeable with the original boxes. They are compact and ergonomic, so they can be connected perfectly to the original connectors.
Furthermore, these coils allow the elimination of the rpm limiter installed on some standard power boxes, enabling in this way the full exploitation of the engine's power and torque even at the highest regimes, up to 20.000 rpm. These electronic coils are based on capacitive discharges, therefore they allow maximum limitation of circuit transients during voltage discharge, while obtaining a virtually perfect peak voltage on the spark plug (35.000 - 50.000 volts depending on the engine regime); moreover they grant extremely high discharge voltages and currents with surprising steadiness with respect to engine rpm variation.
Primary Gear Set 14/39 Ratio
Our Price: $94.00

Malossi S.p.A. is pleased to offer its new series of final transmission gears for scooters and maxi scooters.
These new gears were created by exploiting our 20-year experience in designing and building gears for competition and road scooters.
The new H.t.q. gears were designed and built with straight teeth to minimise losses through friction and stress on the supports. Moreover, our gears increase ratios slightly enabling you to exploit the full power of your scooter, thus significantly increasing its original performance potential.
