Hey! Name's Felipe, from Toronto.
Fairly new to riding, first few years I was riding a 78 KZ400, liked the bike but too under powered for the highway. As of this year, I've been riding a 76 CB550F and loving it. Nice light bike, very nimble and enough power on the highway.
Did some mods to the 550, mostly cosmetic, but planning on putting on a CB750 boxed swing arm and dual disc brakes up front over the winter and will definitely need the forums expertise.
Here's a before and after.
