Have just been musing over what bits of this build were actually present on my original M900, or rather the bike I rode after a few alterations.
When I purchased the original back in 1996 I obviously took it out for a spin immediately, so the good news is that the forks I nicked off my brother (see above) do count as an original part, even though they were swiftly replaced by a set of MAG 21s, and were put back on the bike when I let him have it.
The original build had CODA brand cantis so these went and were replaced with m739 v brakes and shifters (1998?). These brakes were recovered with the forks...but they are not truly original either.
So the only truly original bit I will have are the forks and seat collar! Triggers broom.
