Distance swingarm-sprocket on std bike?

As I have Marvic rims, and before that had Yam 5.5" rim, I don't have a clue what the distance is. I am about to manufacture an off-set rear sprocket, and need to know how much off-set i should go for. Thx in advance!

I am fast, but sometimes terribly wrong...

I need also the inner distance between the swing-arms, if you measure with a standard swing.(I have the YZF750 swinger, so if anyone has the distance between the YZF swinger and sprocket, with a correct chain alignment, that'd be the best...)

Pretty please? Measurement between swingarms right in front of thhe rear sprocket, don't need an exact figure.

I have a YZF swingarm too and I am not sure what to do with chain alignment.
Now that I think of it, I have a TRX swingarm laying around somewhere and a wheel... Hmm, maybe the best thing to do is just to put it together!
To be continued.

Using the yzf wheel, I just turned my standard trx sprocket round so that the dished side faced inwards.

I did exactly the same, but the chain scrubs the YZF swingarm every now and then.

Dished sprocket would probably work, but i have a different rim which means original sprockets don't fit. (Different centerhole, hole pattern etc). The Marvic rim might also have different hub-width, but this i don't know....

Hi Hans!

I try to give you the figures tomorrow (30.04.) evening - would that be "early" enough

Future greetings from Munich!

Hans, do you still need the measurements?

Thanks, but I've ordered the sprocket already. Went for 4 mm off-set, haven't received it yet so can't say if my guess was right...

Hi Hans!

I didn't really forgot to measure

But, hey, yesterday I realized that the distance between the arms

of the swing arm is difficult to measure with the rear wheel installed ...

Anyway, the distance from the outer edge of the left swing arm to the sprocket is (about) 18 to 20 mm (also difficult to measure with the TRiXie standing on the garage wall with a car on her left side and with no accurate measuring tool other than a folding rule - but didn't you say you wouldn't need exact figures

)

Belated greetings from Munich!
