Triumph T160 rear wheel offset

Can someone please tell me the direction of offset of the rear wheel rim on a standard Triumph Trident T160? The factory manual tells you everything else you need to know, but the wheel in question is dismantled at the moment. Looking towards the front of the bike, is the rim pulled to the left or the right relative to the hub? Answer would be much appreciated.

To the right, which should also place the offset joint line between the hub spoke flanges over towards the right hand side, and the speedo drive ring on the left-if the wheel is built correctly.

I can give you the rim offset measurement if you need it?

The factory manual does give a clue, as the L/H rear wheel outer spokes are longer than the R/H outers.

Les, you're a star, thank you! As far as the rim offset measurement is concerned, the factory manual specifies 1/2" from the hub disc surface to the rim. Is this what you are referring to, and do you agree with this figure?

Dave,

To be honest, I'd forgotten the offset measurements were in the manual, and yes, I'd agree that 1/2" from the disc face of the hub to the outside face of the standard WM3 rim is correct.


[Edit] I can always post or send photos if you need to see any spoke lacing details?

Les, re spoke lacing details, I am going by the manual when it says that both sets of inner spokes must be in tension when the brake is applied in the direction of forward motion. I think that this determines the lacing pattern? If you think otherwise, yes, please send some photos if it's not too much trouble.

Thanks again,

Dave

You seem have everything pretty much worked out, but here's a photo which may help.



One piece of advice I would offer you is to fit the sprocket/disc through-bolts in the hub and tighten them (with extra washers or spacers under the nuts to take the place of the disc and sprocket) before you start to build up the wheel, otherwise the through-bolt holes in the two hub half sections can be pulled out of alignment as the spokes are tensioned-which would mean slackening everything off and starting again if the through-bolts couldn't be fitted through the hub.

(And...no, the chain isn't rusty, and yes...the split link spring clip is fitted on the inside intentionally-as it's a heavy duty 630 chain and the link rubs on the case if it's on the outside)

Thanks for this, Les. A good tip on clamping the hub before building the wheel. I don't know why the factory didn't dowel the two halves of the hub. The front is the same.

Your chain looks grand :wink:

Do you still need measurements I have 1 sitting in the shed , unmolested

Splatt — thanks for your kind offer. By unmolested, I assume you mean as it came from the factory? The factory manual gives 1/2 inch as the offset, as measured between the disc face of the hub and the edge of the rim. It would be interesting to see if yours is the same. So yes, look forward to that, thanks!

right, disc flange to rim 11.5 mm, close enough to 1/2'' for a wheel,s sprocket flange 23mm roughly rim just under 76mm wide

Splatt — thanks very much for going to the trouble to measure this. Your measurement and the factory's tally. I am comfortable with this wheel now.

Cheers,

Dave
