Not set in stone but i think I've opted to pick up an R6 or CBR 600 instead of a 1 liter bike like i've been looking for. I've recently test drove them both and can't decide which i prefer. The R6 has a more aggressive throttle response while the cbr is a slightly more comfortable ride. Anyhow, that's beside the point I really need something i can back up without having to stand next to it. That's where my dilemma comes into play. I really would like a bit more than stock power. Suggestions on performance parts that are semi-easy to install and cost-efficient?
