It's just a 125EXC done up to fit in with a Sherco based team. Probably one that needs a 125 2t to fit in. 125 'Junior' class enduro is big in Europe.
I'd like to see Sherco do a 2t Enduro - they've their 2t Trials engines to go off.
Hopefully the Ossa 280 engined Enduro bike surfaces some time this year.
