Those wheels should look great, remind me of konig feathers. Also, I've never seem a rear muffler setup like that. How's the sound? It looks like it should be relatively quiet with that resonator just behind the can.
Also, I have to say I'm jealous. My wife and I honeymooned for 11 days in New Zealand, and if it wasn't for family I think we'd probably move there. Flew into Auckland, rented a car, checked out the north and south islands (hiking, rafting, caving, kayaking, mountain biking) and flew out of Queenstown. Only thing I didn't like were the damn sandflies in the fiordland area.
