The key is knowing if the S200 is a variant of the "gy6 standard". You can always find gy6 speed parts for any gy6 engine. You need to do some detective work: my Kymco "KL10" engine is actually a gy6/qmb139, so for which there's heaps of aftermarket parts. Kymco dealers don't freely give out this information, so you have to dig around in the black market - or buy lunch for your Kymco dealer.
