Welcome. I came from the dirt side too. I've only been on the street for about 5 years now. Easy transition from the dirt. Dirt is great experience. Enjoy your new R3, and ride safe. The little R3 is a ball of fun. My little R3 reminded me of my old 250 2-stroke dirt bike, in terms of weight, ergos, and how narrow it is.
Went with the red R3 and am picking it up tomorrow, passed my bike licence yesterday, and got the last of my gear today... I'm add ready as can be and looking forward to having some fun learning how to ride.
