Hi Mk 2 the one to go for at the mo.Mk 3 no discounts and not yet proven .I have had 3 a mk 1 and 2 mk2's. The Mk 2 is EFI twin disc up front and with immobiliser and parking brake. Good for 90mph easy 110 miles to reserve good in the wet and sporty handling .They are incredibly useful and the best handling scooter out there.The Mk3 is a redo different frame wheels bodywork more sporty looking but looks fragile ,the one at the NEC looked shagged out after a week of people sitting on it and very scuffed .They were in short supply last year and could not be got for love or money as the Italian Post office bought up the lot.Now easier to get but seem to hold their value . I sold my mint 10000 mile 54 plate one for just under £4000 to buy a new 07 Mk 2 for £5500 So not bad eh?Use ACF50 through winter and no corrosion if not usual disc/fastening corrosion and centre stand looks rusty if not cleaned. I love em very popular in france Spain and most of all Italy,where you see guys in sharp suits tearing down the streets.We dont seem to get the idea here but they are one of the best bikes around to those who have owned one!!
