Hey gang, curious what's that sharp ring with a 90º bend right below the chain for. I've never seen it before on any other bike, hence my question. Plus it interferes with my chain adjusting tool, and also damaged it yesterday while removing the stupid chain cover's inner 4mm bolt (using vicegrip pliers). I was able to repair it about 98% perfect, so no need to do anything right now, but if there's no justifiable reason to keep it (like the rear chain guard), I'd like to remove it when it's time to ditch the factory tires. Thx. With a tail tidy in place, rain would make a royal mess out of my bike anyway, so no need for any other rain protection anymore. And also without messy chain lube anymore (I'm using Tirox Synthetic wax now, which makes zero mess), no need for chain covers either, so removed the rear one, and installed a sexy (modified stock one) front sprocket cover. The removal of that ring would finish the sexy look. Ha ha.

Pretty sure the ring is there to stop chain oil from running down the sprocket and potentially getting to your Axel. As for the front skeletonised cover, you may get chain oil on your shoes and pants. Been looking at doing it myself but haven't yet for that reason. Let me know how it goes, if it's all good I might do one too.
Thank you for your reply. If that's the reason, then I wouldn't be worried at all removing it. For the chain to 'run down the sprocket' it'd have to come off. There's no way my chain is coming off unless it breaks, and then the ring wouldn't do any good . Or are you referring when you remove the rear wheel? But even then, don't really see the need for that. Maybe there's a different reason? Hmmmm. And on my cover, the chain lube I'm using (Tirox synthetic wax) makes ZERO mess. Lubed the chain really well, and there was absolutely no residue under the cover after 100 miles, so not worried one bit. Besides, the vents are sideways, so you would have to put a crapload of lube for it to fling sideways. What can happen is throw dirty water if it rains; that I believe, but maybe not even that. Don't plan to ever ride in rain on purpose, so not a big issue to me. And with a tail tidy, rain would make a royal mess on my bike, so a little more wouldn't make any difference. Ha ha. Many folks did that mod. Hopefully one of them caught rain already, and can shed some light on that. I'm curious too .

The front sprocket covers aren't just for keeping chain lube from running, they keep dirt out. This is the area that accumulates the most ammount of lube and grease so it becomes very attractive place for dirt and moisture to build up. Also, the covers keep your pant leg out of the sprocket.
Not exactly sure what that rear ring is for. First bike I've seen it on. I would imagine it's to allow the chain a better place to turn on if the chain were to jump. Usually when a chain jumps, it'll get down into the axle area and cause damage to the swingarm and eventually jam and break. I would imagine this guide would allow the chain to remain off this area.
Have seen the aftermath of a few chain failures. Scary shit.
Thanks RB. With the front sprocket cover mod I (and most others) did, there's no way anything can get caught in there, so zero worries there. Some folks either completely removed the cover, or left just the surround frame, neither of which I find acceptable. And with the chain wax I'm using now, there's zero mess, so not only I did the front cover mod, but removed the ugly rear chain cover too. Your only applicable point in my case is more dirt might get in there now, but no way more than the rear, so I don't see it as a problem, since I always replace both tires and sprockets as a set, whether the front ones look good or not. And finally, I kept the original cover, and could always put it back .
On the rear 'ring', your explanation is the best I've heard, and the only one I can think of that makes sense, so probably the reason for its existence. I don't mind it being there, especially after being able to fix it perfectly (functionally. It just has a scratch). Thank you for your input .
