Hello from Iowa! I'm new to this site and R3 ownership. I just took delivery of an 06 Classic three weeks ago. My only regret is winter is coming and I probably have only a few more 40+ degree riding days left.
I knew the Rocket would be a beast, but I have to admit I'm surprised at how well it handles for such a big bike.
My other bike is a Bonneville T100 which I've done a number of mods (K&N airbox removal, pipes, bars, lights, led conversion, tuneboy, etc.)
Not sure what I have planned for the R3 since it doesn't really need anything. I'm sure some performance mods are in my future, but I can't say it needs it - I can't see me taking this bike to its limits ever.
