I recently bought myself a CX from ebay here in the UK.
I really didn't need another bike, in fact I was trying to sell two Morini Darts (buyer backed out) and in all I have about 13 bikes (Cagiva, Morini, Motobi and now a Gilera).
The CX was running when I bought it, although it had been off road for a year. It went through it's MOT fine, but then the clutch started dragging when the engine was hot. A strip-down revealed a clutch that was worn, but within limits and no obvious cause. Cleaning and re-assembling and filling with fresh gearbox oil seems to have done the trick and I rode it to work today.
Longer term, the engine has to go. It may perform pretty well, but I'm used to the endless power spread (3000-10,000rpm) of a Morini V-twin. A Nordwest engine might be nice, but I think it will probably be converted to battery power to replace the Cagiva Freccia electric conversion I've recently sold. There is at least one electric CX racing in Italy.
Of course, I could buy another one and do both (If I can find one for the right price).
