THE LEADER IN SPEED CONTROL DEVELOPMENT

2. TRANSVERSAL VARIATOR HIGH LIGHTS
More Acceleration
More Punch
More Response when opening and closing throttle
More High-End Speed
Less Vibrations
More Power to the Wheel

3. TRANSVERSAL VARIATOR Automatic Transmission How it Works
Dual Pulley system
Transmission Belt
Centrifuge force moves the pulley to allow the belt to change its position

4. TRANSVERSAL VARIATOR Automatic Transmission How it Works
Low speed

5. TRANSVERSAL VARIATOR Automatic Transmission How it Works
High speed

6. TRANSVERSAL VARIATOR How It Works

7. TRANSVERSAL VARIATOR How it Works
Original versus J.COSTA

8. TRANSVERSAL VARIATOR Advantadges and Features
ADVANTAGES
Simple construction
The design of the bell and the way the gliding rollers slide over it, increase the range of “gears”
Shorter first “gear” at low rpm (better acceleration)
Longer sixth “gear” when the variator is fully opened (closed pulley)
The power at the wheel is increased at any speed, especially in the range of low to medium speed, allowing greater accelerations. This happens because we are able to make the engine work closer to its maximum torque range

9. TRANSVERSAL VARIATOR Advantadges and Features
With the traditional variator you can hear the typical ringing of the rollers hitting the bell
With Transversal Variator the engine becomes smoother and less noisy
The absence internal friction in the Transversal Variator provides a better touch and a faster response in front of the traditional one
There is no contact between the bell and the body of the variator. This enable the pulley to react instantaneously, when opening or closing the throttle
In the traditional variator, the movement of the bell is mechanically guided so friction is greater and so is the response of the system

10. TRANSVERSAL VARIATOR Advantadges and Features
J.COSTA variator is the only system in the market that increases performances in the whole rpm range
With the traditional system if you want better acceleration you need to reduce the weight of the roller. This way you always need high rpm to start moving and you lose high-end speed
With J.COSTA you will always have better acceleration with no dependence on the way you open the throttle
With J.COSTA you never will lose high-end speed

11. TRANSVERSAL VARIATOR Advantadges and Features
J.COSTA Variator closed
Traditional Variator closed

12. TRANSVERSAL VARIATOR Advantadges and Features
J.COSTA Variator opened
Traditional Variator opened

13. TRANSVERSAL VARIATOR Construction features
Machined CNC aluminium
Stainless Steel Bells
Bronze bushings with graphith inserts (to lubricate the slider without grease)
High-Tech Plastic Gliding Rollers

14. TRANSVERSAL VARIATOR Very Important Recomendations
Never Apply grease to the slider, remove all the grease present in the crank shaft and slider before assembling the J.Costa Variator
The nut of the crank shaft must be tightened at the recommended Torque, always using a dynamometric wrench, never a pneumatic one
With Piaggio Leader 125/150 engines, you must change the original belt to a 200cc one, with double toothing
With Honda 125/150 engines you must assemble the belt of the injection model
You must always use the original belt

15. TRANSVERSAL VARIATOR Very Important Recomendations
Always use the original rear pulley, spring and clutch
The ever-changing engine designs may cause an incompatibility issue for J.COSTA Variators
If you find a slider with the kit, it will replace the original one. If not, you will use the original slider
If you find a washer with the kit, it must be installed between the bell and the crank shaft

16. TRANSVERSAL VARIATOR Very Important Recomendations
Yamaha T-Max: Before untightening the variator nut, you must remove the cover. Then untighten the nut, remove the original variator and install the J.Costa Variator. Put the spacer and lock the variator using the Yamaha tool, so you can tighten the nut to 160Nm. Assemble the cover again

17. TRANSVERSAL VARIATOR Very Important Recomendations
When do we need to change the gliding rollers?
In a traditional variator we will need to change the rollers when they are not round anymore
When using a J.COSTA variator, gliding rollers need a small period of adaptation during which they suffer some wearing. This wearing is absolutely normal. We won’t need to change the gliding rollers until the rider feels that the engine works at higher rpm and at lower punch
The average durability for a T-Max and Big Megascooters vary from to km (every belt change), and for small Megascooters from to km. But it always depends on the way the rider uses the vehicle

18. TRANSVERSAL VARIATOR Very Important Recomendations
Some units of the carburetor Yamaha T-Max have a slider which is 71,5mm long, instead of 72,5mm long. In that case you must install a 1mm washer. (we have a kit for that)
between the slider and the bell, when using injection belt
between the bell and the spacer, when using carburetion belt

19. TRANSVERSAL VARIATOR Potencial Market
The continuous growing market for scooters and automatic vehicles give us very nice potential options for nice business
It is an exclusive product, nobody else can produce or sell it
Only one set-up for each model
It is a legal way to increase the vehicle performances. As we are not changing the engine performances we don’t need to Homologate the new performances
High capacity to be the first. We are able to develop a complete new variator for any new vehicle in a couple of weeks and place it in the market in a month
