With things like stem, carbon bars, thin tube/tubeless, light post, road seat, ect. I think it would be possible to get it under 40.Kram said:05 Demo 8 - 41.5lbs exact
SPV 4 way with ti spring
EX823 (05 rims)
Spec Pro tires 2.4"
With Maxxis tyres it would be 42.5lb
40lb would be possible say with a new 06 Boxxer and a different rear shock but I think under 40 would be stretching it.
