I think the stockers running at the front are a bit more than a road bike, a few years ago Hunts had a superstock Fireblade that Michael Dunlop had used in that years TT for sale and in the ad it said well over £20,000 had been spent building it, off the top of my head I think the exhaust cost £2000 on it's own. I'm presuming the cost of the standard bike was taken into account in the total as well but what's a brand new Fireblade? £11-12,000? So another 8 grand or so on top of that.
