With my Terra getting close to 10k miles (or I may have hit it already, not sure), and the bike not even being a year old, I am beginning to wonder how long I can realistically expect to have this bike as a commuter. -Is it reasonable to expect 100k miles out of this engine? -How does it perform in the BMW counterparts with the different head? -Anyone have an idea on what the most miles anyone has achieved with this 650? -How many miles do you have on your Terra so far? When I get home I'll verify my miles and post them. At this rate I'm looking at 11-12k miles a year on this bike.
