Ok, I think there is some confusion over the 'six days' bikes we are discussing here.
If Speedy Maniac & Berkyboy are referring to the rental bikes that GG supply for the actual six day enduro, then yes, they will have obviously have some changes to them. They will be racier with more race-focused suspension than standard.
The six days bikes I refer to are the ones available to the public through any of the GG dealers here in Europe. I have sold 5 of them so far (250 & 300) and they have all been identical to the regular enduro bikes, with 2K3 ignition, regular forks & shock etc. My own EC300 six days has 2K3 ignition also.
