That was an attempt to kill the tread drift, as it was going places which the OP's bike couldn't

Back to the chain problem, looking at Buggington's bike specs, it's a 7 speed, which gives problems to what chains are avaliable, unfortunalty the Ti-Nitride chains (that I have been able to find) are only available from 9-11 speed, so that kills that idea.

Another option would be to look at what lube is used, something like a wax based lube, Pedros Ice Wax, or White Lightning, or one of Finishline Ceramic based lubes, all of these should be good at rust prevention, however as I mentioned, being in the UK, and at this time of year means a lot of salt type grit on the roads, which is corrosive to bikes, just giving the bike a clean water wash when you get home will help in prevening some corrosion, but won't prevent it totally.
