after 50k+ miles, my 09 C14 keeps running as or better than new. I do not have those heat issues, probably because I ride with touring boots.
I have consired trading it to get a MY12 but I see no advantage to justify the $$. Waiting for a next generation with the bigger engine and goodies like cruise control.
