Well I rode EVO250 in 2013.
My bike was on;
Michelin Trials Uni Rear
Shinko Trials Front (probably won't be running this tyre again this year though hahaha)
Managed a first in EVO 250 and a 2nd (on count back) in EVO 250 Under 49yrs
I can tell you that I don't recall going around the outside of anyone
Really all this tyre talk shits me. Just put your trials uni's on and go race FFS. Hope to see plenty of you there!
Cheers
Shaun
