Motorbike question...

Pete.:
Looks good. It'd be interesting to know the exact application. On most swingarm/wheel spindles (well, all that I've seen) the bearing inner races are clamped together by the through-bolt. As standard, a swingarm would have a spacer fitted loosely in the space between the bearings and the spindle would pick up that spacer pulling the lot together. For alignment, you would fit one particular side bearing into the arm first and press it against a shoulder then press the second bearing in up to the spacer.

Since the larger bearing in your sketch does not sit against a shoulder on the shaft you made, that won't be the case here. A piece that size would fit into quite a hefty bike and I'd be wondering about what flex or movement there would be from not having the bearing races all clamped together.
AdeV:
I now have some pictures from the bike builder. Apparently, the piece fitted nicely & is working fine (phew!)

Here's the swing arm:



My piece fits in the far right hand bit. Here it is fitted:






On the bike frame:



And the finished(ish) article:



As you can see, the bit I made has completely vanished  :lol:

Still, it's nice to know it's doing the job  :thumbup:

Nice work Ade! Glad to see it is doing it's job.

Nice looking swingarm too. Definitely not stock.

Nice work, its a stock zrx1100 swingarm by the looks of it. The 1200 is the double tube version, but the 11 only got singles. Theyre nice on the eyes and its common to see them getting swapped in other stuff.
Call me mr swingarm spotter, Ive got a chart on my forum of all the dimensions and photos and stuff :D
