Putting you on the spot... which do you prefer?
I bought the Guzzi brand new in 2013, having fallen in love with it when I saw it at the NEC show in December 2012. It's Mk I 'Special' 5-speed and pre-ABS. It's red and white, similar to the Baker Express Interceptor, amd I absolutely love it. The new 865 V7 (the Classic in blue and white) looks gorgeous and if funds permitted (which they don't at the moment), I would take one out for a test ride.
In a similar way, I loved the look of the Interceptor when I saw it at the NEC show. It looks like a 'proper' motorbike from my youth! When I sold my Ariel Square Four I had enough in the bank to but a new one and customise it. I only did 400 miles on it before laying it up as my winter project, so it's too early yet to say which I prefer. I bought a silver one (the only one I could find at the time - they were hard to get last spring, with a long waiting list). I'm fitting a 'Rocker Red' Conti GT petrol tank and CGT seat and painting the mudguards (fenders) red. Engine cases and other parts powder coated gloss black, plus lots of other mods.
I normally say that my favourite bike is whatever one I am riding at the time. (My other bike is a Triumph Thruxton 900).
