Replacement Chain

18 posts in this topic

What is the stock chain on the WR450F 2013 and what replaces it? I usually run RK chains but does the WR require a narrow chain, for example. Thanks for the education in advance :goofy: . I have over 100 hours on the "new" WR and it's running great.....just the chain is worn out. :ride:

Just a 520 chain of your liking. I would get a O OR X  ring chain. RK or DID are great chains.

Thank you, Sir. I'm happy a narrow 520 is not mandatory. I can stick with my usual RK X ring chain then.

F150joker style (fellow tt member) installed an RK GB520GXW on his 2009 YZ450.

He replaced it (before it wore out) with the RK GB520MXU because it was lighter, not much more money and quite a lot narrower. He was racing/riding in the desert on his YZ.

There might be more clearance in the stock chain guide with the smaller chain.

The 520MXU is rated at 9,000 pounds while the 520GXW is 8,500. But too late I already installed the new GXW. Next time around I'll definitely be looking at the MXU though!

No problem. You can't go wrong with RK chains ... they're just like Excel rims ... the gold standard.

 

FWIW, the DID VT2 and Sunstar XTG are both 4.4 lb and the RK 520MXU is only 3.8 lb @ 120 links. Not sure what the GXW weighs in at, but probably 4-5 lbs.

Good question. I know the GXW is heavy I'm sure in the 4-5 pound range. I'll look it up.

The GXW 520 is 3.75 pounds per 100 links and the 520MXU is 3.10 pounds for 100 links. So the 520 GXW is 4.275 pounds for 114 links. :ride:

Anybody know of the best counter shaft sprocket. I used what was in my parts bin, forgot who made it.  My last one bent the teeth. I think that the counter shaft sprocket sprocket is the weak link for a really good chain and Supersprox rear.

Well off topic of the OP ... FWIW, Sunstar and Talon have both outlasted OEM and JT for me.

Run the heaviest strongest chain that you can buy, if you like your pocketbook. Weight savings isn't worth it, if you pay for your own parts and ride a lot.
