If you're mechanically savvy you can do the work yourself. I change my 888 SP5 belts every 12,000 miles or 3 years - they degrade over time and it's not worth the risk.
The comments so far on clutches are frankly not correct. My 888 shares the same clutch basket as later 999 models and the plates are 10% cheaper to buy than for my Honda VTR1000 and as it's a dry clutch, you can change it yourself in under 5 minutes flat and that's stopping for a cold beer in the middle!
Oh - noisy clutches are a Ducati characteristic and worth lettign the noise out - after all a dry clutch gives you more horsepower to the back wheel than a wet clutch so you might as well let people hear it.
Italian Harley? - get outta here! Ducati's are bristling with technology whereas Harleys seem to be as technologically advanced as your average 1920's farm tractor!
