If you choose Aylesbury go for DWR. Avoid Ducati Aylesbury like the plague.
Duc Aylesbury are great for selling bikes, clothing, parts etc but when it comes to servicing my experience has always been bad. So bad I decided to go to the independents (Rossocorse) when the bike was still under warranty. Okay this was a few years back but doubt they've changed.
Definitely get more for you $ (don't have a pound key!)
In fact if my bike was still back home, i'd even ride the 50-70 miles every time to rossocorse to have it done.
