Been here before with this story Series of 1-2 mile straights punctuated by 3 roundabouts,R6 came off the first roundabout behind me and stayed there till we got to the traffic lights in the town,speeds from 50-140+ and he COULD NOT pass me. Now if you say he wasn't trying,then how many bikers do you know have their chin on the tank/arse in the air when they are just relaxed? Seems feasable to me as i can carry a lot more speed through a roundabout than a bike,brother in law agrees,and he's a mad biker.
