J.Costa is a Spanish manufacturer that produces scooter variators. Over ten years ago they introduced a completely new type of variator. This variator differs from the traditional variators because the commonly used variator roller weights were replaced by gliding weights. This unique system is completely developed by J.Costa. Just as spectacular as this system are the advantages and performance this new technique produces. An increased power on the entire power band, better acceleration , less vibrations and faster throttle response. Dips in the power curve are part of history. Each variator J.Costa produces is specifically developed for and tested on the concerning model. This guarantees an excellent performance.
