Specifically, opinions of those that have used them on a litre sportsbike or something similar in power output/tyre wrecking abilities. The Dunlop Sport Smarts (not sure if I'm a fan - but that's another story) on my 09 cbr1000rr are almost done at 4000kms and I'm looking for a tyre that might last me through winter and also heat up a little quicker on these cooler days. I've used the Road Attack 1s on a 1200gs and was really impressed. A few kilometres of country riding on a cool morning and they were track day hot and super sticky, and kept those characteristics for 7-8000km of centre-stand grinding fun. The rubber stayed fresh and sticky until down past the wear bears, unlike some other tyres I've used that appear to last a long time but really just harden up and stop wearing/gripping *coughpilotroad2s*. My main worry is that those quicker warm up times/lower optimal temps won't translate so well to a higher performance bike. So really interested in any comments from litre bike riders that run sports touring tyres. Just don't suggest pr2s.
