TJT Racing released its new line of variator rollers for 2012. The variator rollers are available for maxi scooters, regular scooters and quads in different sizes and weights. It’s pretty much something for everyone in there. Unlike the Polini and Stage6 adjustment rollers, the TJT ones are molded around the weight and therefore last longer. Additionally they use some special material that includes resin, aramide and polyamides which also helps with the durability. Unfortunately I have not received an MSRP price but I assume they go over the tray at around 8 – 10€.
Besides rollers TJT specializes in the production of clutch discs, automatic clutches, speed variators, springs, exhaust systems, carbon reeds, brake pads, brake shoes and brake discs. I believe they have some expertise with all this since they are doing all this since 1958 already.

I have a Kymco spacer 50 with a 70 BBK FIT a 17.5 arreche carb. A naraku sports variator with 10 gram rollers ,a standard clutch with 1500 contra spring and standard clutch springs plus a twist control on the contra spring a de-restricteb CDI unit and a Tecngas Q-tre exhaust the problem i am having is I keep shredding belts
If possible could you advise me on the set up as to what weight rollers I need ,and what springs I need .I am planning on fitting a 18% gear up kit as I don’t want to blow the engine up as the power band is round about 8500-9000 hope you can help, Kind regards Bob Mc
Are the belts ripping? My guess it’s the 15% contra spring. They put too much torque on the belt and it rips!
