Rear Tyre rubbing on the shock linkage

[AndyFaeLarky]

Just noticed an issue with my Street Triple RS 2020.

Looks like the rear wheel is rubbing in the rear shock linkage, nothing has changed recently - what the feck is causing this???

Just popped out to the garage to have a look at mine and I can't see how it would be possible for the linkage to contact the tyre. at rest there is at least 2" clearance from the linkage to the tyre and as the suspension comoresses the linkage moves away from and not towards the tyre.
 I think the tyre marking has another casue but no idea what it is.

First thing to do is have a good look at he suspension linkages as if something is rubbing it should be fairly obvious as it will me marked/rubbed.

Thanks,

Yeah, I did have a look at the linkage that is closest to the tyre and its shinny and look similar to the rubbing marks.

The chain does need adjusted - dont see what that has to do with it tho..

Ok,

Had had the wife sitting on it and bouncing up n down (which was fun to see) and it looks like there is no chance of the linkage hitting the tyre.

It's bloody strange - need new tyres anyway, maybe just comming to the end of their life and wheel spinning easier.

Oh and adjusted the chain - looks like is wasnt right from the factory, the markings were different from each other.

I have adusted it to be even on both sides now.

Not being adjusted true, would lead to increased tire wear and would cause slight "dragging" .... a tyre expert on here may know

The swingarm marks are not necessarily accurate, you need to use an alignment tool to do it properly. Easy enough to make something DIY if you google it.

I did my chain about an hour or so ago. I used a bore gauge  / internal gauge thingy, to get both sides even then used the bolts to adjust...works a treat     

This one (bore gauge "c" fitted between the swing arm inner casting and the adjuster body. Set them up the same using the adjuster bolts...check the chain tightness and adjust evenly / by the same amount either side from there on in

Looks similar to the my tyre after some gravel got caught in the hugger. I heard it before I saw the damage though.

I was thinking hugger too. Slight loose or flexing, or fitted very close to the tyre. Does the tyre expand slightly with centripetal force when the wheel is spinning at speed. Tip of the hugger on my 2015 is sort of two points.

There is nothing fouling the tyre.

Convinced its the tyre, its done 3500 miles so think it is just breaking up - have order a new set of boots for the bike anyway.

Dunlop Roadsmart 3's.
