Why use malossi or polini? Maybe the TJT will perform better...it does not hurt to try, seems like everybody's answer for everything is malossi. Mexicano: I have experience with that TJT variator, and as far as I am concerned it is the best one I have seen so far. As you may know, it has an inner bearing which allows better performance than the traditional solid smooth surface (where the slider inserts) like the other variators have, Just make sure you lubricate the inner bearing with dry lube regularly, the inner bearing is also replaceable. I've been meaning to ask euroscooters about replacment bearings, maybe you can ask around or contact them, they may ask you for a picture of the bearing, because it is hard to explain..but if you can get your hands on them, that variator will last for a good while, the performance is worth it
