Any one running these ive just bought a set for track use staring next month and was wondering about heat cycles weather or not I should really care. I would like to used them till there spent on track days with out say having to chuck them due to the fact ive given them too many heat cycles. In one day. My mate runs them on his track day R1 and ive never heard him say anything about heat cycles, but my local dealer started blabbing on about cycles the other day and its got me thinking. Ive ran metzler racetec K1 and K2 on the road back in the day on my aprilia rsv bought them part worn and they worked a treat on the road. Mega grip So im kinda thinking its ok just checking with the lads before i bin the new ZX10
Echo, use warmers. I use SC2's from new with warmers, but don't worry about cycles as it's only one per track day.
