J Costa/Turbo Kit Variator for SYM Maxie Scooters RV250 and Citycom
J Costa and Turbo Kit are brand names so same product.
The J Costa Variators are the most high tec high performance variators I have come across. Using what they call Gliders as weights that push the drive and ramp plate together. Instead of rollers or sliders this are more like pins. They lost long and from reviews that simply to the job well for top end speed and bottom end torque. They are very tough. Solid is what to comes mind after working with Malossi Polini and Dr Pulley who all make great products also.
Exhaust and Fuel injection Module also made by Turbo Kit.
Variable complete transversal. It is ideal for 4-stroke engines. You get to leverage the power wheel getting 5-8% more acceleration and more open design than the original drive more top speed is achieved. We suggest a good squeeze or damage that may occur will not cover the warranty. Are advised to check every 5000 kms and replace the rollers and the central bulon if they are worn, if well see in the next review. There are bikes that hold 10,000 kms without problems and others that will have to change.
