I loved the MT03, except it had the worst seat ever, sore arse after 10 miles. It's the only bike my wife got uncomfy on the back of too. Got an Airhawk inflatable seat which helped lots, but sore back if more than 100 miles, sold it. Original pipes sound fine, say my neighbours, and it was great with centre stand, rack, for short journeys. Expensive fuel if over 65 on mway.
BMW not as Mad Max, but if you want it for ten years...
