Variator Rambla 300 J.Costa

Derbi scooter speed control J.Costa PRO IT629PRO complete. The variator, patented and produced exclusively by J.Costa Competition (made in Spain), unlike normal variator, do not have the usual rollers that run on tracks by varying the diameter of the pulley and thus the transmission ratio but a series of radial cylinders that make move the pulley to the rise in the number of revolutions. This innovative feature allows to have several advantages over traditional variator including:

- Greater acceleration (as it is able to have a transmission ratio of the shortest to a number of engine revolutions lowest)

- Increase of the power to the wheel to any number of rpm (due to reduced friction losses and to his gaming specific transmission)

- Higher top speed (as is able to have a longer transmission ratio to a maximum engine speed)

- Better power and torque at low rpm (the guide will be more fluid and linear to any number of turns and speed especially at low and mid-range)

- Faster response and without jerking (especially during closing and reopening accelerator)

- Less vibration during operation (due to lower moving mechanical parts)

- Reduce fuel consumption

The materials used for the production are top quality and care of the processing with the continuous optimization of the production have allowed the drive cross J.Costa to obtain a level of performance, reliability and durability of its components at the highest levels. Are available on request spare parts, the drive is mounted without any modification to the scooter. The photo is for demonstration purposes only, each model has its own specific variable.
