More of an artists impression than the start of a true mock up, but the vital ingredients are there.
Definitely going to be running an all alloy Tiger 100 motor, the cases in the pic are 47 5T, probably not going to use them but it's not out of the question. The gearbox is good though, a fully refurbished unit from The Baron, complete with needle roller lay shaft conversion, it will be staying.
The tank is the narrowed early Bantam that Toddy modified for the 350 Goldie, so although this ain't the very one that'll be used, something extremely similar will be.
Forks are good in principle, but the sliders are the later type for a clamp up spindle. These will be swapped out for the earlier push through spindle type to accommodate the "Pie Crust" front wheel.
The yokes are the early type with the extra 10 degrees of rake built in, have to wait until the build is further along to see if these get changed to the later parallel type.
Pipes are going to be high levels, more than likely both up the primary side, for that off roady sort of style.
Seriously considering running the muddie at this length, not the height of fashion but it does allow the number plate to be sprayed straight on to it, rather than any form of bracketry hanging off of the side.
