J.COSTA REVOLUTION

The revolutionary J.Costa variator permits a considerably faster acceleration at the lower revs regime offering a stronger torque all along the power curve. Its structure is very simple and straightforward, never the less more efficient and with better performance than traditional variators. Starting from a structure similar to traditional ones, the cross-sectional variator has a different external plate, bells and weights.

There are no slides, no rolls.

Differently from the traditional cylindrical rolls, these weights are shaped like capsules. The plate of the pulley has holes inclined toward the outside where the weights are hosted. When the bell rotates the centrifugal force pushes the weights against the plate, therefore changing the diameter of the surface where the belt travels.

The J.Costa Variator empathizes some of the characteristics of the engine permitting a better transfer of power to the wheel, a more progressive acceleration and a better response to the opening and shutting of the throttle. Together with the unique characteristics of the J.Costa variator, the premium quality materials used to build this product, the care and optimization of the production have all contributed to achieve a extremely good level of performance, reliability and value.

 In contrast to conventional variators:

 This design of variator uses gliding weights, instead of rolling types, which facilitate the variomatic to open linearly, which has proved to be a very simple but effective technological development!

 Its linear design is the secret of the 'turbo effect' provided by these pulleys. Compared to original items the J.Costa units offer a shorter transmission ratio at lower revs, which leads to a quicker acceleration.

Simultaneously, when the weights have reached the end of their travel (pulley fully opened), they also possess a taller ratio at higher revs, providing an increase in top speed.

 

The new PRO speed control series, differs from EVO3 generation by taking a heatsinks within the speed control in a circle provided with projections, between rollers area and bushing area. The rollers cavities are holed for the Press-Depress effect make them to act more quickly and smoothly both at the entrance to a higher gear as the output of a lower gear showing no jumps, ie make the air as fluid dynamic to help the rollers to emerge or be collected faster without increasing fuel consumption.

  • Improve in:
    • Smoother performance.
    • Better aerodynamics.
    • Weight reduction (inertial control).
    • Higher refrigeration allowing less temperature due to the new variator design with sink.
    • Higher quality for all components of speed control, higher durability and less maintenance.
  • We get:
    • Faster operation.
    • Higher reaction on the throttle Press-Depress of the rollers.
    • Reduction of the fuel consumption.

 

The new XRP speed control series (XTREM RACING PARTS), differs from the earlier versions by taking a heatsinks within the speed control in a circle provided wirh projections, between rollers area and bushing area. The rollers cavities are holed for the pressure- depression effect make them to act more quickly and amoothly both at the entrce to a higher gear as the output of a lower gear showing no jumps, ie make the air as fluid dynamic to help the rollers to emerge or be collected faster without increasing fuel consumption.

  • Improve in:
    • Smoother performance.
    • Higher refrigeration allowing less temperature due to the new variator design with sink.
  • We get:
    •  Faster performance.
    • Higher reaction on the throttle, thank to the effect Press-Depress® of rollers.

The new and exclusive XRP is a KIT, composed by complete speed control and high quality belt.


 Urban driving style - EVO 3 URBAN

 J Costa brand offers the best technology, performance and equipment for scooters, creating products designed for our customers who have needs related to security and safety in driving, as well as clients who want to upgrade their scooter to the next level in performance, speed and driving control. Therefore we can say that our products, depending on the customers profile are divided to Urban EVO 3 and Racing Evo 4 models.

Following the success of the Evo 2 version, Urban, Evo 3 high end variomatic not only impresses with its performance values. The improvement made in the choice of construction materials and production quality satisfies the needs of our customers.

Safety of our customers and the safety of their loved ones is very important to us and that is why we offer the new EVO 3 Urban.

The improvement over its predecessor are obvious at first glance. The Variomatic unit itself has a ceramic coating to increase its durability and more importantly, reduce the overall friction created. The roller weight ramps have also received this treatment which lowers the wear rate of this part of the pulley considerably and extends the overall life of the weight rollers and ramps. Also, the movement of the weights is reduced by the protective ceramic coating on the EVO3, preventing excessive wear. The Variomatics cover has also been redesigned to optimise the overall performance potential.

The main advantages of the new EVO3 URBAN are:

  • •   A plus in acceleration: more impulse while driving uphill; 
  • •   Power control at all times: safer overtaking;
  • •   linear response of the engine means more reliable ignition;

Jcosta products are tested on the road, they are manufactured from the highest quality materials on the market and they passed exhaustive quality control.

+Safety  - Consumption

*J. Costa variator does not harm the scooter, or its motor, always work on his own torque, and therefore does not affect the durability and lifetime of the scooter or its motor.

 

Racing driving style – EVO 4 RACER

J Costa brand offers the best technology, performance and equipment for scooters, creating products designed for our customers who have needs related to security and safety in driving, as well as clients who want to upgrade their scooter to the next level in performance, speed and driving control. Therefore we can say that our products, depending on the customers profile are divided to Urban EVO 3 and Racing Evo 4 models.

Exclusive variator EVO 4 of J. Coste provides multiple benefits to the racing style of driving. It is designed for those who want to improve the performance of their scooters.

The main advantages of the new EVO4 RACER are:

  • •   + 20% more horsepower (approx)
  • •   Greater acceleration with  4 Newtons of force more (approx)

 

EVO 4 Racer variator is made of CNC machined aluminum with ceramic treatment. It consists of  Stainless steel bell, Isolated core of bronze with grafit inserts for lubrication. Weight rollers are made of high-resistant plastic. Also, the bolt has been treated for anti friction.

 

Compared to the EVO3 model, the EVO 4 has a new bell and weights, delivers better performance and it is designed for those with a sports spirit.

 

The unique Variomatic technology employed in the function of the EVO range has been once again improved and proves it with even more performance throughout the rev range!

 

*J. Costa variator does not harm the scooter, or its motor, always work on his own torque, and therefore does not affect the durability and lifetime of the scooter or its motor.
