Thanks for the advice guys,
I had the bike delivered about an hour ago, the noise it makes is awesome! I had to get the old enduro gear on and give it its final ever blast ( down a private road

) before i strip it. Having only ever riden enduro type bikes and motocross the rapidness of the thing was a bit of a shock! If its half as quick in a car ill be very happy
I still cant belive the sound it makes!
