we've covered about 150 miles on ours, our engines and trannies feel really tight. The first bit of our break in was on motorways which isn't the best start (yes we did vary the revs/speed etc) but they don't feel anywhere near as good as the demo, with a horrible drive through vibration between about
3750-3950 in 5th or 6th. My wife's is exactly the same. Hopefully they'll get better with miles, we're sticking to the lanes for now with lots of varied revs and engine braking.
Mine had about 30psi in the rear shock (base RT), it's now set to 60psi, front tyres had 16psi, now set to 18, haven't checked the rear yet, must keep an eye out for that link. Mine too feels squirrelly, but think its just me adjusting from two wheels. It is very sensitive to inputs, I find putting my weight on the pegs helps.
cheers
