We Stock a large selection of Malossi tuning Parts,if we do not have what you want we can order ,We also now stock a good selection  From PM  Tuning and Polini  

WE Stock Leo vince TT,ZX ,ZX chrome PM Tuning and Malossi Exhausts

Making the right choice

Choosing the correct exhaust is vital for the performance of an auto 2 stroke. Power delivery that’s too peaky can lead to difficulties in setting up, maintaining a balance between good all-round performance or just good top end speed with Slug  like performance off the line.We run a dyno test on the new PM 71rc

Racing pipe.And it gave an extra 2.52bhp over a standard 50cc with the clutch washer removed.

The Leo vince ZX gave an extra 2.17 bhp  with the restriction washer  removed. Price Start from £89

Replace the reed block with a new Malossi or Pm High flow carbon reed block.The reed block  will help increase throttle response and give more mid-range.

Replacing the variator will improve the usable power range .and on most Autos Give more top speed..

Malossi Kevlar Reinforced Drive belts,Eliminates belt slip due to power increase.Also a worn belt will not help,

A drive belt in a tuned bike should be replaced every 1500miles.

This is a great site explaining how the pulley system works and weight of rollers effect the bike http://www.apriliaforum.com/forums/showthread.ph p?t=8960

We all know that clutch behaviour only affects acceleration, and not speed.

Delta Clutch was born in the racing scene as an irreplaceable tool. On track it has allowed the Malossi team mechanics to adjust automatic clutches of the scooters rapidly and accurately, depending on the type of track and the type of engine tuning.
The perfect operation of this automatic device is fundamental to obtain a good start from stand still, and to exit from tight bends where the speed of the vehicle decreases. The advantages offered by these clutches when compared with the standard ones are huge, even for a road vehicle, because they allow sophisticated tune-ups for a very wide range of engine revs..
Fly Clutch
The new automatic clutch, is the result of the experience that Malossi engineers have accumulated with the Delta Cutch® adjustable automatic clutch.
This new clutch has been designed and constructed to adapt perfectly to a standard vehicle and guarantee impeccable performance on all occasions.
The Fly Clutch® automatic clutch is supplied pre-calibrated according to instructions supplied by our engineers after exhaustive testing on accelerometer benches to check the reliability of every part of this new

Malossi product.
Therefore, the Fly Clutch® is a high-technology replacement that offers maximum reliability and extremely long life: a state-of-the-art component for all racing scooters.

The MHR Replica line of cylinder was created especially for the International Scooter Trophy ­ 70cc Automatic Class. These cylinder kits were designed to guarantee maximum performance in this category, while at the same time assuring extremely long product life.

In order to guarantee these special characteristics, Malossi MHR Replica cylinder kit have pistons with two chrome-plated rectangular segmants and a compression ratio of 13.8:1, plus torque value of 7.35 N.m. (o.75 Kgm) at 8.000 rpm and power of 6.6 Kw (9 C.V.) at 8.500 rpm.

The MHR line is the results of Malossi's many years of experience in European and National competitions. These new cylinder kits are composed principally of cylinder- piston ­ ring ­ head.

70cc Kits From £83

Malossi S.p.A. is pleased to offer its new series of final transmission gears for 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.

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 with our cylinders, variators and the special Malossi Kevlar Belts, allowing to fully exploit your vehicle's note able 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.

Fuel system Malossi

These systems have been specially designed and calibrated for high-performance motors, and are complete with all accessories needed for assembly . MALOSSI is the leader in the design and production of special fuel systems for motorcycles and scooters.
MALOSSI systems are the result of intense research and precision drawings and calculations. The suction pipes, reed valves, and air intakes designed by MALOSSI undergo efficiency tests and destructive tests to check their performance and reliability.
Carburetors are customized for each vehicle according to the specific characteristics of the motor and air intake, and are completely calibrated for dosage of the air-fuel mixture under all power delivery conditions.
MALOSSI produces special components for fuel systems in order to supply a product that responds perfectly to the needs of the most demanding customer.  

Too often we neglect the simplest and in fullest sight components of our engine, whereas we could allow it to work better, to give better performances and to be more long-lived, with little operations.
Let's consider for instance the feeding system, which supplies the "store" of air and petrol tightly releted to the engine performances.
The filter task has vital importance. In fact on the one hand it must prevent any impurity (which could causes serious damages in short time) to get into the engine; on the other hand it must give has to allow the best possible breathing, without stifling the engine.
These two tasks are one the opposite of the other, and only a first quality filter, which is the result of careful studies and of Malossi experience, made of the best materials, can conciliate them.
Therefore, it is not by chance that all the best manufacturers start right from the filter design, which is the first component of the engine "breathing chain", in order to make highest performance engines suitable for the racing employ.
Undisputed leader both in making racing scooter engines and special feeding systems, Malossi have had the chance to get ready the best scooter filter so far produced.
