I'll throw in my vote for the Triumph Integra...picked one up at the beginning of the summer and it's been great. I've worn it in a good range of temps (55 to 90+ degrees) and it's been good all around..of course it gets a bit hot when you're sitting in traffic when it's 90+ out - but I'm not sure there is a jacket out there that wouldn't. It is vented very well, has removable shoulder/elbow/back protectors, and has the stowable rain shell.
This website carries them (and all other Triumph stuff) at a good discount:
