saw same bike earlier at the premier on the a49, warrington - not too sure if it is an sp2 now tho cos looked like there was a pillion - didn't see a 2nd bike but there were 2 riders...
i'd love a closer look though, looks and sounds really nice definately a big v twin, not a duke or a suzuki

what's confused me is acer sponsor yamaha and i don't know of a big yammy sports v twin???
unless it's a monster mt-01 but ive never seen a full faired one??
any ideas what it might be?
