How bout the other way? What would it take to fit a 899 arm set up on a 1299? I am assuming a arm, wheel, axle. What about the caliper and brake line?
Arm, wheel, axle, disc, sprocket, chain, front sprocket (520 pitch), brake line, hugger, chain guards, mud/oil guard etc etc
It?s a lot of kit....which i might have for sale!
Caliper is the same fit
