Ducati ST4 will make a great projective bike. Needs very little to get it back on the road. New front tyre, spare pair of front forks, plus heaps of other spare parts.
I bought this bike when it was a year old as a financial write-off. It took me a couple of years to get it back on the road and registered mostly because second hand plastic parts were so hard to come by and so expensive brand new. It was registered on Feb 2006 and remained registered until a couple of years ago when I stopped riding it due to a heart condition.
Over the time it has had well over $50K spent on it (receipts available) including a refreshed motor using all genuine Ducati parts.
The bike has been incredibly reliable over the years and comes with many various parts which I have collected over the years.
