i didn't go clutch pulley style yet. i will be getting one though.
i would like to highly advise against a performance variator with an idle clutch function, at least the er2 with the clutch function. they seem to have a tendency to not actually let your bike idle and make you spend more money on the clutch pulley anyway. plus, because of the way its set up, you have basically no low end. it isnt actually a clutch, its a bearing on the shaft and the variator grabbing the belt is the "clutch grabbing". horrible. i cant fathom why they designed it like that, but they did and i hate them for it.
