Sean Butcher, testing at Larkhall, Scotland

How old were the tyres in each of these clips?

[@emilwedin7826]

Exactly I don't think he had the exact tire wear on both sessions but an overall conclusion is that some tracks favour the rotax and some the x30.

@@emilwedin7826 Yeah at Larkhall Rotax is definitely a good bit faster than X30, the fastest laps at the British champs at Larkhall last week in Senior X30 were low-mid 49s whereas the fastest laps in Senior Rotax are high 48s
