Saw these on an American dirt bike site, i really like em, be great to have a go at doing one of these, and when i say "doing one of these" i dont mean that sort of doing them EL T !!!
sorry for not knowing what weight savings had been made from standard by changing the wheels, forks and swing arm
Is it really that important? Would it stop you from buying one? For reference, I think it will have made a few kilos difference either way. Does that help..?
My guess would be 20kgs down, c160ish with very little fuel, depending on stuff like extra weight for the lifting v savings from single discs, wheels?? Battery, other bodywork and cans/system
But then the centre of gravity is higher, it's got larger diameter wheels and it's on knobblies, so any comparison with the original bike is futile. It's not the same bike any more. Much more fun to just get on it and find out the hard way...
