Ludicrous perhaps, but not unusual; Ducati dealers are getting greedy with labour charges like most others in the auto business. (£45 plus VAT per hour at the place I use, eighteen months ago it was £35)
My '99 900SSie just had a major service which came to £524. However, 4 hours of it was replacing 3 shims, so I was a bit unlucky. Try and find a good independent mechanic; I'll probably do so myself now that the bikes over 5 years old - won't fall much more in value so that main-dealer stamp isn't so vital!
