First was a new white R1250RS, number plate ending NNY - left me for dust just after the Wandsworth roundabout!
Second was an R1200RS, exchanged a friendly fellow RS Rider's nod at the lights on Wandsworth high street. I think we both then rode out on the A3 heading south but I didn't see him again after the A3 becomes a national limit.
Wondered if either were on the forum - have seen NNY before, also on the A3.
