Already available. There's a guy I know from the SWTR (South Wales Trail Riders) forum who's got one. He got it from Thor in Cornwall. He's written a lengthy report on the forum on his initial thoughts of the bike and by all accounts he likes it (he normally rides a Gas Gas 300 2t)
The 2015 models retailed for £5395 + otr, i guess they're all sold now , don't know how much the 2016 model will be but they should be out any time, The 2016 comes with frame guards and an o-ring chain thats about the only difference so should be about the same money
