Ducati can print what they like, they dont make the Law do they??
As regards the methesis tester, Neil at
www.cornerspeed.co.uk has got one, oh and a full service (12000 miles) on an S4 will take a good two days, including changing fork oil, brake and clutch fluid, taking the cams out to inspect the rockers,checking and adjusting valve clearances etc. Add the cost of rent, electricity, capital cost of all the equipment and special tools needed plus the guy doing the work needs to make a living wage and i can assure you that the independants are not getting rich on servicing Ducati's.
Alsoemember that they are not servicing bikes seven days a week, 52 weeks a year. Neil has three very quiet months over christmas with almost no work coming in but he's still got to pay rent, eat, heat his house etc.
