More punch off the line, powerful acceleration and a transmission that responds to every twist of the throttle with noticeable dynamics: the Malossi Multivar 2000 sports variator brings genuine Italian performance feeling to air-cooled Piaggio 125cc three-valve engines. Developed for riders who expect more from their Vespa Primavera, Sprint or Piaggio Liberty than the standard transmission setup can offer.
The Multivar 2000 is one of Malossi's best-known performance products. Its strength does not lie in simply increasing engine speed, but in deliberately changing the transmission characteristics. Specially calculated roller tracks, precisely manufactured components and optimised variator geometry help make more effective use of the available engine power during acceleration.
On an automatic scooter, the variator plays a major role in determining how the engine behaves during acceleration. It continuously changes the transmission ratio and therefore determines at which engine speed the available power is transferred to the rear wheel.
The standard CVT setup is designed as a compromise between riding comfort, fuel consumption, noise emissions and legal requirements. A sports variator such as the Malossi Multivar 2000 has different priorities: it is designed to keep the engine operating as effectively as possible within its strongest rpm range during acceleration.
The result is a sportier character with advantages in a variety of riding situations:
It is important to distinguish between engine power and transmission setup. The Multivar 2000 does not increase the actual power output of the engine. Instead, it optimises the way this power is used by the continuously variable CVT transmission.
Malossi manufactures the movable variator half from an aluminium-silicon alloy. Machining is carried out on precision CNC equipment, while the running surfaces receive a particularly fine surface finish.
The central technical feature is the newly calculated roller track geometry. Its shape determines how the variator rollers move under centrifugal force and therefore how the transmission ratio changes.
Unlike simply changing the roller weight, the Multivar 2000 directly modifies the mechanical characteristics of the variator itself. The roller tracks are designed to provide transmission characteristics geared towards sporty acceleration.
The product images clearly show the sophisticated structure on the inside of the variator body. Pronounced reinforcing ribs, precisely formed roller guides and the cleanly machined belt running surface illustrate the engineering effort behind the design.
Another important component of the Multivar 2000 system is the variator bush. Malossi uses an alloy steel hub with a hard-chromed, ground and lapped sliding surface.
Together with the self-lubricating sintered steel sliding bush, this creates a guide system designed for low friction and precise movement.
This construction is particularly important because the movable variator half continuously shifts axially while riding. Smooth movement supports consistent transmission progression and contributes to reliable CVT operation.
The kit includes a complete set of Malossi HTROLL variator weights. The rollers measure 20 x 17 mm and weigh 11.5 g each.
Malossi uses a specially developed material compound for its HTROLL weights. The high-strength rollers are precisely calibrated and designed for use in Multivar variators.
The black rollers with metallic inner bushes feature the characteristic white Malossi lettering and weight marking. Even visually, they display the distinctive technical style of the Italian tuning brand.
Roller weight directly influences the engine speed at which the transmission ratio changes during acceleration:
The supplied 11.5 g rollers provide the basic setup specified by Malossi. Additional HTROLL weights are available for individual tuning.
A special feature of this Multivar 2000 kit is the two supplied contra springs in white and yellow. They complement the variator and allow adaptation to different versions of the rear pulley assembly.
The contra spring operates in the rear section of the CVT transmission. It provides the counterforce to the movement of the rear pulley halves and therefore influences the interaction between the variator, drive belt and rear pulley assembly.
The two springs differ in their dimensions and are intended for different rear pulley designs:
The different colours therefore do not simply represent a choice between a softer and harder sports setup. The primary consideration is selecting the correct version for the respective rear pulley assembly.
With the correctly selected contra spring, the Multivar system can deliver its intended operating characteristics. Particularly during acceleration and load changes, the interaction between the two pulley assemblies is crucial for smooth power transmission.
The Malossi Multivar 2000 demonstrates its carefully considered design even in the smaller components. The black ramp plate has a distinctive star-shaped profile and central splines. Three black sliding elements guide the movement within the variator.
Together with the precisely shaped roller tracks and matched HTROLL weights, these components form a compact functional unit designed to work as a coordinated system.
The two clearly distinguishable contra springs underline Malossi's systematic approach: not only the front variator is taken into account, but also the operating characteristics of the rear pulley assembly.
Suitable for the corresponding air-cooled 125cc three-valve engines. The installed engine version should be checked before ordering.
Installation must be carried out in accordance with Malossi's specifications. In particular, make sure that the correct contra spring for the respective rear pulley assembly is used. The two supplied springs are not freely interchangeable.
The front pulley is not included in this kit. The Multivar 2000 is combined with the pulley specified for the respective vehicle.
The actual improvements achieved depend on factors including the condition of the engine, drive belt, clutch and individual vehicle setup.
Malossi identifies this product as intended exclusively for competition use on designated tracks. Use on public roads is therefore not permitted without the appropriate legal assessment and, where required, individual approval.
The Malossi Multivar 2000 is aimed at riders who do not simply want their 125cc scooter to rev higher, but are looking for a livelier and more direct response. The combination of specially developed variator geometry, high-quality sliding components and matched HTROLL weights gives the CVT transmission a distinctly sportier character.
The carefully engineered interaction with the rear pulley assembly is particularly interesting. With the two supplied contra springs, Malossi takes different transmission versions into account and provides a solution designed around the complete CVT system.
The result is a sports variator with genuine racing heritage, precise Italian engineering and one clear objective: more dynamic acceleration, stronger pulling power and a riding experience that makes the available 125cc engine feel noticeably more responsive.
