Once again, thanks to the constant work of our R+D department, we are always investigating and innovating to offer you the best of the market. 

For this reason, we are presenting a new product to the market, the unique and revolutionary TRANSVERSAL J.COSTA CLUTCH, with its patent.

The most characteristic thing its operation. It has a revolutionary system, where thanks to the centrifugal force, the weights work as a transversal way, pressing the springs and these to the disks. The operation is so similar to the J.Costa variator.

The design and production, is done by aluminum CNC machining with a hard anodized treatment to get more durability, as also, lubrification and refrigeration.

Performances and feelings that you will get:

  • Aggressive and faster snatch.
  • More reaction and sensibility in the throttle.
  • Increase the brake engine.
  • More retention when you close the throttle.
  • Less extreme use of the brakes.

Available models:

  • Yamaha T-MAX 530cc
  • Yamaha T-MAX 500cc
  • Kymco AK 550cc


With URBAN exhaust , you will get a increase a little the sound respect to the origianl exhast also It decrease the weight repect to the original one and this increase the performances. 

With RACING exhaust, you will get a reasonable beautiful sound and it is higher than the original, also you will get more performances in you Scooter, you will get more top speed. 

SPORT exhaust, with high quality stainless steel collectors  and aluminum silencer, it pass a high quality control because this way the design and aspect will be perfects. 

It is perfect for mouting with J.Costa PRO or XRP and this way you can get more perfomances in your scooter,  that is to say, more power,  torque and less weight. 

What we get? 

  • High performances in all power ranger. 
  • Lightness

Also this 2019, for SPORT and SPORT Carbon,  we have the catalized and homologated option because this way you can pass the technical inspection of vehicles, without any problem. 


Always, we are always thinking, obviously, on their PERFORMANCES, they are:

  • Smoother performance.
  • 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.
  • Faster operation.
  • Higher reaction on the throttle gas Press-Depress of the rollers.

But, why we have not stopped to think about what makes us really  FEELS? What the J.Costa variator transmit to us?

  • Running without stress, giving a little gas, the motorbike gets more top speed without having the feeling of going “deep”.
  • Thanks to a higher reaction of throttle gas and quickest answer engine, we can get more agility and security, as well as, faster and safer overtaking.
  • Sense of freedom, of speed,  that you can reach the end of the world.
  • In addition to its function of gear change and thanks to its patented system, the J.Costa variator, allows to control the motorbike at all times. The bank test curve is fully lineal, range from start to top speed,  variator offer performances at all times.      

Never forget that the J.Costa variator it is UNIQUE in the world and it has an extreme QUALITY:

  • Body made of hardened aluminum CNC machining with ceramic treatment.
  • Stainless steel bell.
  • Bronze inner bearing, self- lubricated with graphite inlay (no grease needed).
  • Slider by titanium nitride and graphite and antifriction treatment.
  • Plastic weights injected in high-resistance material, Kevlar and carbon fiber reinforced to high durability and optimum sliding.
  • In case of XRP, include a belt, it is manufacturing with high Kevlar quality and a washer with CNC machining with ceramic treatment.
