I sold my CBR900 when I bought my house but I'm back at the point where I can afford one again and I think it would be a bit of a fuel saver for the commute to work. I've had my heart set on an R6 for a CBR600 for a long time now but I started thinking that if I'm sitting in traffic for ~45 mins each way, a sports bike may not be the most comfortable way to go. So I started thinking maybe something a bit more upright like a naked bike but everything I look at that's around 600cc is learner legal so down on power. So I am looking for suggestions on what else to look for that would be comfortable on longish commutes. Or even for people who own sports bikes, how you find it over longer periods?
