They did a 999, Biposto, R, S. I think they did an SP but are a real rarity and often came in Race Rep (Xerox) colours.
A lot of people may have replaced some parts of the lesser models to make them look like the S's or R's so beware.
Base model have Showa forks and rear shock but the S and R models have Ohlins. However the Showa standard forks are pretty damn good and fully adjustable compared to other Jap OEM crap.
Brakes are 4 pot Brembo's (say no more) which will stop you on a 10p. Only difference is the R and S models have fully floating discs.
Bit of a diet in the R & S models too as are about 3-4Kg lighter than standard model.
If you want to take pillion the BiPosto is the model or ensure the bike comes with seat conversion (Single to Double)
No single sided swingarm (which is why purists never like the 999 or 749) but does make it easier for garage and maintenance.
The easiest comparison is not to your 10R but to a 750. But with oodles more torque. You can ride the Duke all day in 2nd/3rd as it will pull from everywhere. They are around the 130Bhp mark...
The new 848 has more power than the 999 but less ooomph.
Hard work at slow speed, as any heavy duke is, but once moving make total sense and really flow. Throttle can be a bit on or off in low gears.
Full Service history is a must, and must have had the timing / cam belts done regular. A big bill usually follows any Duke service so if its due for one, haggle.
For me...I would snap someones arm off for one of these. I totally love them and for me, any Ducati bike is the one I would have in the garage over anything else. Nothing short of Bike Porn!!!
Get it, Love it, Never Look Back!
