Have a look at Paulin's helmet cam footage:
?ecver=2" width="513" height="360
Shows good, hard racing and riders - Herlings and Cairoli and The MX Panda! - going for it in every corner, every straight, every jump, with great lines .
And, you can see that both Cairoli's and Herling' rear wheels stepped towards each other (moreso Herlings) up that hill - yes, a bit of a close one, but, MX Track surfaces tend to be rough, and 450s at full noise do get somewhat 'loose'
I'm getting a bit sick and tired of a few here bleating about Cairoli being 'nasty' to Herlings. Hell, Herlings is lucky that he didn't get 'pinged' for going over the Acerbis markers, early on ( Cairoli did too). Nah, just highlighting / joking at the sort of 'snowflakeism' we are tending to see from various 'fanbois', in both MXGP and SX.
This sport ain't tiddly winks, boys
