AlanO - if it helps I'm in Stevenage and have a new 420R - SV body. I'm 5'11" & under 13 stone and my wife is a lot smaller - and we love the SV. We primarily tour, with the occasional track day, and wanted the less 'snug' version for the little bit of extra space around us - especially elbow room, for when we're touring. You're welcome to come and try it for size etc. when allowed. Cheers.....Richard
