Variator Malossi Multivar 2000 Voge Sfida SR450X >2026

Malossi Multivar 2000 Variator for Voge Sfida SR450X from 2026 onward, developed to modify the operation of the CVT transmission and achieve more effective acceleration and more progressive ratio variation.

The variator works by using the centrifugal force of the rollers. As RPM increase, the rollers move along their tracks and push the movable half-pulley, causing the belt to gradually move up toward a greater operating range. The shape of those tracks largely determines how the transmission ratio changes while accelerating.

In the Multivar 2000, Malossi recalculates the profile of the roller tracks to control that movement more precisely. The objective is for the engine to remain closer to the rev range where it delivers the best torque and power while the transmission progressively lengthens the gearing.

This results in a transmission with better response when opening the throttle, a more linear ratio transition, and more stable RPM during acceleration. It is not simply a matter of making the engine rev higher, but of ensuring that the variator, belt, and rear pulley make better use of the available rev range.

The half-pulley is made of aluminum-silicon alloy and machined using high-precision CNC, with a diamond finish on the working surfaces. Precise geometry is essential so that the belt can move uniformly and make proper use of the full travel of the variator.

The hub uses hard chrome-coated alloy steel, subsequently ground and polished to reduce friction in the sliding area. The assembly also incorporates a self-lubricating sintered steel bushing to maintain smooth movement of the movable pulley.

The Malossi HTROLL rollers are calibrated and manufactured in high-strength CPT. Their weight and the profile of the tracks work together: rollers that are too heavy cause the variator to close earlier and reduce RPM, while rollers that are too light delay the gear ratio change and keep the engine at higher revs.

What is Malossi aiming for with the Multivar 2000?

• Better acceleration: making more effective use of the engine's useful RPM range.
• Progressive gear ratio change: thanks to the specific profile of the roller tracks.
• Greater RPM stability: preventing abrupt variations during acceleration.
• Optimized belt travel: to make better use of the available CVT transmission range.
• More precise operation: machined components and sliding surfaces specifically designed for this application.

During assembly, we recommend checking the condition and width of the belt, the variator guides, and the pulley surfaces. Fine-tuning the rollers is also important: varying their weight directly modifies the RPM at which the engine operates during acceleration.
