Someone did a 999 motor in a 696 frame. had issues with size and clearance on the radiator. I think he finally sorted it out and sold a few or was looking to.
The SF basically stole that business. and now with the SF 848... that and the fact Ducati said... "Monsters are air cooled, 2v"... feasible? no. At least as an official Ducati product.
But making one yourself... have fun and report often!
.. I believe that was a Desmoquattro motor in a 696 frame... Which I though t was cool.
With the SF out with the 848 displacement, i'd say its a guarantee that there will be no 848 or any other liquid cooled Monster ( ala S4R-RS).. There'd be no point
