I just bought a used 2008 triumph Daytona 675 with 12,400miles. I took it home and noticed black spots on my front rim. I figured it might have been from the road so I cleaned the rim. After a second ride the spots were there. What could this be from? I am assuming it has to do with the brakes. But not sure what part. I wrapped a zip tie to my front brake lever and throttle squeezing it. Going to leave it there overnight to see if any leaks from the brakes. I would hate to clean the rim after every ride.

That is weird. It looks like grease or oil. I'd be checking the fork seals and perhaps the front wheel bearings too.

I've also thought it might have to do with the wheel bearings also but I've check already and it all looks normal. Forks are not leaking at all. Like TwoWheelWonder mentioned it might just be break dust. There was a little on the rear also.

Thanks

I've had brake dust on my wheels before and it doesn't look like that. Normally it's an even film of dust that wipes off easily. Unless that's after you've tried to clean it with something and it's smudged?

I haven't smudged it. That's how it looked after 2 hours total of commute and traffic. I'll take a picture tomorrow of the first hour of riding. It mostly looks like a cone shape with a dark spot at the tip of the cone. Then fading away as it spreads into a cone shape.

Here's a pic of the bike btw.

Brake dust. I bet those rims have a fairly cheap powder coating on them without a clear. Brake dust sticks to them and give that comet looking effect. I have a second set of rims that are powder coated cheaply in white and they do the same thing.

Take your brakes apart and clean everything up. It will lessen the severity but it will always be there. Or you can stop using your brakes :smile:

No need for multiple threads. If it does end up being brake dust. Throw some wax on your rims and it will be very easy to clean off in the future. Re apply the wax every season for best results.

That's a good idea, while I'm at it should I do the tires too. Or would be better to douse them in armor all?

^I usually just save my leftover oil from last season, apply liberally and you should be good to go. It adds for a great shine when hit with direct sunlight. Did i mention it helps me drift, just like those ICON videos. Win.

get a microfiber towel and lightly spray with goo-gone, wipe the rims then clean with soap and water. This will remove any grease stains that are hard to remove. Then apply rim wax so that dirt and grime doesn't stick to the rim. See if that works.

Thanks! Rim wax is a good idea. Yesterday I grabbed a dry microfiber and wiped the dust off. Works well for a quick clean. Then I'll detail it and use rim wax on the weekend.

Rim wax is a great product, you could wipe your fingers with a white glove on my rims and wouldn't find any dirt, grease or grime

Nothing better than a good rim job.

I would eventually take the rims off and take them to a powercoating shop and have them put on a good clearcoat.
