A technological advancement that promises to transform the market: the RatioZero CVT transmission eliminates belt wear, delivers greater torque and efficiency, and is already making its debut in partnership with the Yamaha T-Max.
A CVT transmission system that uses no pulleys or belts, but instead gears in infinite variation? It sounds like the stuff of science fiction, but that’s exactly what engineer Edyson Pavilcu has created with the RatioZero system. Let’s explore this innovation and understand how it promises to transform the automotive industry and other markets.
What is CVT transmission and why is it important?
The CVT (Continuously Variable Transmission) transmission is famous for providing smooth and constant acceleration. Popular in cars like Honda and Toyota, and also in scooters like Yamaha, this system uses variable pulleys and a belt to continuously adjust the gear ratio. This results in greater driving comfort and fuel economy.
The concept of CVT transmission dates back to cars from the Dutch company DAF, where the system stood out for its simplicity and efficiency. Over time, it has gained space in several brands and models, especially due to its ability to keep the engine in the ideal power range.

In the world of motorcycles, the CVT is widely used in scooters due to its reliability and practicality. In cars, it is ideal for optimizing performance in urban traffic, offering a more linear driving experience. However, one weak point is the possible slippage of the belt, which can compromise torque and response.
RatioZero: A new approach to CVT transmission
Thinking about overcoming these limitations, Edyson Pavilcu developed RatioZero, a revolutionary system that completely eliminates pulleys and belts, replacing them with gears.
RatioZero uses a modified planetary gearset with individual satellites that create virtually infinite gear ranges. These gearsets operate independently, shutting down gears that are not in use and preventing movement of the entire gearbox. The result is a more efficient and responsive transmission.
In addition to preventing belt wear, RatioZero offers increased torque and energy efficiency. This means that vehicles equipped with this technology will be able to have better performance, less maintenance and an improved driving experience.
The RatioZero has already caught the attention of major market players. Yamaha will be the first to implement the system on its T-Max scooter, but the possibilities go much further.
Yamaha T-Max: The first vehicle with RatioZero
Yamaha’s choice to launch RatioZero was no coincidence. Scooters like the T-Max are perfect for testing the technology due to their use in urban areas, where quick response and efficiency are essential.
RatioZero's versatility is impressive. It can be used in cars, enhancing performance without compromising economy, and even in bicycles and wind turbines, where efficiency is crucial.
Although the system is now ready for production, there are still important steps to be taken before it can be implemented in automobiles.
Practical tests on vehicles are essential to validate the durability and performance of RatioZero in different conditions. Despite this, the innovation already has two registered patents, which guarantees its exclusivity in the market.
The role of patents and the automobile industry
With Yamaha as an initial customer, RatioZero has a promising future. If the tests are successful, other manufacturers could adopt the technology, marking a new era for CVT transmissions.
RatioZero promises to be more than just an innovation – it could redefine the concept of CVT transmission. By eliminating the limitations of the traditional system, this technology opens the door to more efficient and versatile vehicles. Now, It remains to follow its journey to the market and wait for the next revolutions in the world of engineering. automotive. Who knows, maybe soon we will be driving cars equipped with RatioZero, enjoying a completely new driving experience.
