More power for your maxi scooter: CVT Kit Maxi Hi-Speed Evolution Yamaha T-Max 530cc & 560cc, tuning variator kit from Polini.
The Evolution is an upgraded version of the Hi-Speed, fully revised and improved with low-friction tracks and Polini’s innovative, patented lubrication system that ensures constant bushing lubrication. Power transfer is optimal and friction losses are minimized.
technical data polini evo hi--speed variator:
- Maxi Hi-Speed Evolution variator with 2x 8 weights (25x15 - 12/14g)
- Air Speed pulley with large blades for better cooling
- Counter pressure spring + 30% with Evo Slider spring plate
- Polini grease
Advantages of the Polini Hi-Speed Evolution variator
At the core is the Hi-Speed variator, a true technological masterpiece. Its standout feature is the patented lubrication system with two built-in O-rings, reducing friction losses while increasing reliability and lifespan. A large reservoir supplies grease continuously via a special spring, ensuring top performance even under extreme conditions.
The sliding surfaces, angles, and tracks have been revised and optimized to improve acceleration and top speed. The sliding sleeve is made of nickel-plated steel with a DLC carbon coating, derived from motorsport and aerospace applications, reducing friction and wear.
The variator comes with a reinforced counter-pressure spring and two matching sets of variator weights. The rollers are coated with a new nylon-aramid fiber mixture. Combined with polished tracks, this further minimizes friction, improving shift response and optimizing acceleration.
Polini Hi-Speed
The famous Polini brand lists their "Hi-Speed" CVT as part of their catalog for many years. Of course, the CVT has been upgraded and improved over time, but the basic principle is still the same: a tuning variator for original and slightly tuned engines with a noticeable increase in performance compared to the original variator.
Performance Polini High Speed CVT
With newly calculated and optimized angles, the Hi-Speed variator allows an extended power band. This shows above all in noticeably better acceleration, but also in a slightly higher top speed.
Two integrated O-rings provide the sleeve with better lubrication, resulting in less friction.
The low-friction, robust chrome coating ensures reduced wear and increased service life.
For heavily tuned engines and engines with a significantly larger displacement, it is worth using an overrange CVT.
scooter CVT
Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.
CVT Parts:
- Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
- Ramp plate: Holds the weights in place.
- Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
- CVT roller weights: Adjustment weights that play a critical role in function and performance.
original, Sport and Oversize CVTs
- Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
- Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
- Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.
You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
