LC4 Chain and Sprockets

Any recommendations for replacement chain and sprockets for an LC4? For the front sproket I'll stay with KTM, the rear sprocket and stock D.I.D. 520X chain held up well, but I'm open to suggestions.

I went KTM sprockets and RK X-ring chain when I replaced. I originally had an alum on the rear, but it wore out in 2K miles, so I'd recommend steel from the get go. The KTM sprockets are price competitive with aftermarket.

The KTM rear steel came black anodized and looks kinda cool (around $25).

I did JT rear steel, DID gold X-ring chain and ktm front, I only went w/ the JT rear because the KTM steel was out of stock at my favorite place. I'm on a 640 Enduro, not Adventure by the way.

I am about to redo my drivetrain; front is pretty near shot. The shop grabbed me a Regina X-ring (I think...) chain, and stock 16T front. They wanted to sell me the 950's steel 42T rear for $60!!! Luckly someone here saved me from that stupidity.

I went with a KTM steel rear and stock steel front. The aluminum rear is silly IMHO since we don't really need the weight savings and the steel lasts, what, 2-3 times as long at half the price...

I went with a KTM steel rear over aftermarket due to the council of a that someone special mentioned above. I will let him speak for himself if he chooses. Since the OEM sprockets are really competitive I guess the question is "why not?" (out of stock is ok).

Chain Gang

G'day,

I've been using Chain Gang stuff for a while, seems to hold up well. Haven't worn any out yet! Pricey but seems to be worth the money. Cost me about US$280 for front & rear sprockets and RK GXW chain. The new design superlight is more of a swirl pattern than the simple pattern shown on their web site.

I've used DID X-ring chains for a while, but Paul said they've had several reported breakages on the big KTMs, so suggested the GXW instead.

OEM stuff was utterly shagged and overdue for replacement at 6,400km.

LC 4 chain and sprockets

I replace my originals with Sidewinder parts (www.sidewinder.com).
Awesome performance last 8000 miles! Chain and sprockets show no wear.

So here is a picture of my front sprocket that the shop said is shagged:



What do y'all think?

Here is the rear (once again):



about 7,500 miles on the stock rig from new.

Those KTM steel seem pretty good. Not a lot of size choices though. I like the beefy triangular teeth. Why do front sprockets have giant teeth and rear sprockets usually have pathetic wimpy teeth? Is it my imagination..

Looking at your rear sprocket it looks shot to me, must be the stocker - the front looks to be in much better shape. I changed out mine around 9000 km and it was much the same story, the soft rear sprocket was completly shot while the front still looked servicable. Of course I changed the whole works {the right thing to do} making sure to put a steel one on the back. I now have the same Km on the replacements and they show very little wear. I also use Superclean chainlube with good results when compared to some of those sand & gravel magnet type lubes.

Hard to tell from pictures, but I concur: front Okay, rear shot. In fact, the rear sprocket looks about like the one I just replaced.

Front looks ok, rear looks like it needs replacement...
Besides it's always better to replace both gears and chain since with only new rear the chain might wear faster
