Any chain can get chewed up split or not split. However these bikes run a higher risk of getting your chain spat out and cause all kinds of part chewing damage, all you need is for the cush drive to be badly worn so that there is a lot of play when you engage the 1st gear from neutral and a combination of a semi worn loose chain and you're asking for trouble.

Seriously this is one single cylinder with a lot of poke in the low rev, you need to make sure at all times that you have a good cush drive and that your chain is maintained (cleaned and oiled, that's where investing in a Scott oiler or similar is a must) and that you never get too much play out of your chain therefore you run it at the intended tension.

I've learnt this the hard way by disregarding those maintenance tips and commuting day and night in all weathers and then one day *SNAP* the chain got wedged so badly in the swing arm, the bike ended up on the back of the recovery truck.
