^^ hmm interesting, they're a little quicker than i thought then.
i know other people who have run 16-17 on 250s, must be down to rider weight and technique.
For comparison, RGV250s run 12.9-13.1 or so according to reports I've seen

(with a good rider of course - i'll go down and run some high 13s when the track reopens haha)
Pity there was no 4 cylinder 2 stroke 250
