Front sprocket - don't make my mistake

Last night I set about changing the chain and front sprocket on my 2015 650. The chain had become progressively more difficult to keep from drooping right after adjusting it, so I figured it was time.

Also, as my Wee is approaching 30,000 km (18,000 miles), I figured I would change the front sprocket at the same time, whether it looked like it needed it ir not. What I saw upon removing the sprocket cover surprised me. The sprocket was worn way beyond expectation.

Once again, besides premature slackening, the chain was showing no signs of failure. I've been contentious in lubing it since day 1, and don't ride in a lot of dust or mud.

So word to the wise: have a peek under that front sprocket cover every once in a while, you may be surprised by what you see (I was).

Wow... so I can only imagine what my 27,000 mile original front sprocket might look like. I better have a look soon. Thanks.

I've got 16k miles and mine has much less wear than that.

Good reminder!

I have had two sprockets on my 2006 DL 650 that were worse than that before I clued in. They were at 66,000 and 62,000 km (think around 35,000 Miles.) Now I check and replace earlier... around half of my expected chain life so I am doing it closer to 50,000km or around 30,000 miles.

Yeah, I was always under the impression that a sprocket would typically outlast a chain, all things being equal. I guess that is not always the case.

That looks like an OEM front sprocket. That is worn way past out!

Front sprockets should probably be changed at least once during a chains life in my experience. The smaller the front sprocket, the more rapid the wear.

Speaking of sprockets, many out there are solid steel, while the OEM has a rubber bushing, as I have been told. Is this true? I have been told that the solid steel sprockets are a harsher ride due to lack of this rubber bushing.

OEM and one aftermarket maker offers the front sprocket with the rubber bonded to it. As far as I know this has nothing to do with ride but is simply a damper for noise. And it works, the ones without this do have noticeably more chain sing.

This is really excessive wear for the mileage. You must be riding in conditions where the chain picks up grit that grinds down the sprocket. If this is so you may be better off with a dry chain lube that does not attract dirt much or at least a lot less lube than you may have used.
Also the front sprocket is symmetrical, means you can turn it around at 10k and have the "new" side of the sprocket in contact with the chain under load.

yeah, the rubber on the sides of the OEM front sprocket is for noise dampening. I learned that last week when I did my first chain and sprocket replacement at 32,000 miles. Although, whether you can tell it dampens noise is up for grabs. I ended up with a new front sprocket that doesn't have the rubber bushings. I can't tell if it make more or less noise. In fact, with the new chain and sprockets, it almost seems to be running quieter over all. BTW, the front sprocket that I took off my bike didn't have anywhere near the wear that Thighrod posted.
