Matchless G50 7075 alloy steering head stems
I’ve made a brace and a third of 7075 alloy steering heads stem for a Matchless G50. My customer has had a batch of alloy bottom yokes machined up so these stems are to fit them.
They have also had some titanium steering head bearings made to use with them, i didn’t make the bearings, and they are about 0.05mm oversize. So the first stem i made to fit the OEM bearing race left the titanium race a sloppy fit, so i’ve had to make them all slightly oversize, which happily corresponded to the interference fit needed for the yoke! so the bearing/yoke land is parallel.
