These are approximate! The bike is sort of trapped in the garage at the moment but I have traced the hoses with a piece of string as best I can. Why not use an old/new conventional cable outer to follow the same route as the hose will take? That will let you get the exact length you need! To give you an idea though here you go:
Front: 610mm.
Rear: 1220mm.
I will try to remember to get the bike out tomorrow and measure them a bit more carefully.
