curvy yoke conversion help

[Typhon219]

Hi all,

I'm in the middle of converting an 02 curvy s to take a handlebar. I've had to give it to my garage to get a couple of bolts loose and do a couple of other bits. They've just called to let me know that the top yoke I have from a naked curvy is a different size to the top yoke from my s and won't fit. I didn't spot any mention of this when I looked into how to do the conversion and thought it would be a straight swap, take off the top yoke from my s and drop on a top yoke from a naked. Does anyone know about this and if there is a way to get around the problem? Would it need the lower yoke from a naked to work?

the N and S lower yoke has a different part number for a reason (offset). most folk get the top N yoke to fit the S bottom by slightly forcing it on. no doubt someone will be along telling you different.

Thanks for the reply. Could forcing it cause any issues like the forks bending at the top? Would the bottom yoke and stem from a naked fit straight in and be a better solution? Sorry for all the questions, I just need to get the bike back together before monday

Hold up sorry, just re read yours and you said lower yoke, not top yoke.

Bibio, on the Curvy, reason for the different part number is due to the N bottom yoke lock stopd being slightly different...it's slightly chamfered/step to reduce the turning circle on full lock.

My guess is, probably slightly bent forks or twisted bottom yoke.

What does 'different size's actually mean?

It should indeed be a straight swap.

i stand corrected

i would go with 21quest's reason then.

if your needing the bike for monday then stick the S yoke back on.

do you also have the longer clutch and throttle cables for the N conversion?

[Typhon219]

21 quest think they said the forks in the top yoke sat wider than in the bottom by 12mm. I'll have a better look when I go and collect it (wheeling it home)

Bibio yes I have a clutch and throttle cable from an n, as well as new braided brake lines from hel. Old brakes are off at the moment so if I can get the new bar on before putting the new lines on that would be better.

Hello, provided it's 12mm difference on both sides(left and right forks), I'd say you do not have the right N top yoke.

Any chance of some pictures?
