190/50/17 tyre doesn't fit in my SP1

I can not find the reason why in my SP1 doesn't fit 190/50/17 rear factory size tyre. On the left side it rubs against the chain. It seems to be to wide. I've got accessory wheel rims and perhaps are misaligned. I have a question. Can anyone give the dimensions A B C D E of the marked things from attached photos (much better view in full size) ? I will be very grateful

P.S.
Most important are B and D for me please.

I assume you are still running a 530 chain?
Also all tires come in slightly different real world sizes.

The real probability it that the right side (if sitting on the bike) axle is farther forward than the chain drive side. make sure you count the same number of lines from the indexing mark on the axle.

Yes, I use 530 stock chain
I have bought used 190 test tire which is real 192mm wide to check it. It doesn't fit at all.
Axle-swingarm marks and lines are aligned same on both sides.

Are you sure that is a wheel designed for an RC51?

Make certain the side collars/spacers are installed/correctly.

Unfortunately, I'm not sure because they were already installed before buying the bike that's why I'm looking for these ABCD dimensions

It looks like OK. I can not even mount them differently.



My wheels are 17" Marchesini 6" wide but I don't know whether to VTR SP

Hey Kizior, I didn't try to mount aftermarket wheels so I'll leave others to help with that but I would suggest you try a 180/55/17 at some point. If you just want the look of a big fat back side, the 190 is the ticket. If you care about handling, be sure to try a 180.

I highly preferred to flog both my 916 and RC51 on the race track with a 180/55 fitted. The 190 turn-in felt slow and lumbering compared to the 180. Both bikes were notably lighter and more flickable with a 180.

If everything is mounted straight with appropriate spacers, your problem may be solved by simply shimming out the rear sprocket a bit but, like I said, consult the other forum members for that. Plenty of experts with rebuilds and modifications around here.

Thx.
I have already ordered 180/55 in case of rapidly forthcoming season but I would find the cause of the problem so It would be nice to hear more advice
