Well I finally got my bike back today. The store people where actually nice to me today. This was a bit of a shock but good to see that they have turned their attitude around Anyway after the swap from the BT010 to the BT012 I must say the handling and stability of the bike has improved 100%. I noticed the difference from the word go. I went around the same corner I came off at at around 35kmh (Hairpin) which is 10kmh quick than I came off. Not even a squiggly or a bit of movement. Take this as you may but I think its a very very Bad idea to mix tyres. I know some of you guys do it quite often but for me it has been a very bad experience. Until your have tried match tyres then no matched you won't know how much a difference it really makes. The bike seemed to lean over far more aggressively with the mismatch tyres (Could have been the BT010 profile) Anyway I'm happy again. The bike looks good and I've finally got the tyres I'd asked for
