What could this be?

[SIM]

Just got back from trip upto Scotland, and noticed a black powder on rear wheel of my 1100gs, anyone got any ideas.

Will strip down and have a look over weekend, but wondered if anyone had any ideas.

Thanks

Brake dust?

Long trip = road dirt and brake dust just got back from a long weekend in sunny Scotland and the rims were filthy .... so you must have been the same places as us

Hoped that was the case, but never seen it all over the rear before

Thanks

I've got a lot of marks on my rear wheel (only on the side with the brake calliper) and assumed it was brake dust.

What I haven't worked out is how to get it off without damaging the rim. Any ideas?

Have you tried washing it?

If that fails try a bit of T cut scratch remover

Yes, dont use a hammer and chisel

Careful folks - this thread is starting to sound worryingly like it belongs in the 1200 section

do you know anyone into old firearms?

In all seriousness have tried all the usual products that won't damage the wheels and they didn't shift a thing. All the products I find that are recommended for brake dust would damage the rim. I blame the previous owner for letting it get this bad, it's properly baked on

I had a rear caliper seize early in the bike's life, the disc got properly hot. I blame that for the black marks on mine, probably bits of read hot pad material burning the rim. I thought it was just crap but closer inspection it looks as though the lacquer is damaged allowing corrosion to start.

Get a pair of cheapo toothbrushes from Sainsbollocks (10p!) and a tube of Autosol! Get down on your knees and start polishing! Works brilliantly!

Don't think we're not watching, waiting and gathering evidence..

Could be the black rubber flap that protects the rear shock from all the crud thrown up. Sometimes it rubs against the wheel and wears away-you'll see the wear marks if it has.

Possibly dead haggis residue, they are beligerant little things and chase motorcycles and throw them selves at the wheels and of course leave their mark.
