I'm in need of a set of tyres for the CBR600 and whilst I've been very happy with the BT020s in central London, I'm not entirely sure they're going to be up to the track day in July. So I'm looking for some advice. It's been suggested by the lovely folk at Honda that I should go for the BT014s. However, my commute and riding style both mean that I don't get to see much action on the side of the tyres so it's really just a matter of time before I square them off! So I've got two questions: Would I be right in thinking that the 020s wouldn't be a good idea, especially for the trackday? If so, is it worth going for the 014s, bearing in mind I can get a cheaper set of 010s - is there any difference other than one is replacing the other? So any helpful advice?
