We made the mould from 2 mil ally, just bent it to the right shape in a bender. Weight of the RBH is 240 grams. It won't shatter in a crash due to the twaron (aramid like kevlar, only black not yellow), and they'll be baked for 8 hours. The nav tree will fit any bike.
How thick is that Alloy plate?
