Chain and Sprocket

Hi everyone from the UP of Michigan!!! I have a 04 wr450f and I was wondering what preferences you have on chains and sprockets! Steel or aluminum, sizes and what not. I know stock is a 520 chain and the length is 114, and the front sprocket is 14 tooth and the back is 50 tooth. Brand preferences or didn't sizes for trail riding! Thanks!!

Also any reviews on JT chain and sprocket kits!

Steel will last a lot longer than aluminum sprockets but aluminum is lighter.

I personally like DID vx2 or DID ert2 are both great chains. I run it with a talon aluminum sprocket it has held up great so far. I have heard the iron man sprockets are great too.

I'm a big fan of steel sprockets.  I had an aluminum sprocket for a bit, and it seemed to wear extremely fast, probably only 30% of the lifespan of a steel sprocket.  I don't know if it was due to all the sand in Michigan, or just the way I ride (I tend to run low RPMs and torque through things) but I went back to steel.

Thanks for starting the thread, I am in the process of researching the same thing for mine as well. 

JT, Sun, Sunline, or Ironman sprockets

 

I prefer JT

 

DID VT2 series chain will last for many, many years if maintained.

The one on my Honda went 350 hours !

Thanks for all the input!!!

Does everyone use an O-ring 520?

 

So long as you dont mind buying a new one every couple months, I'd bet a non-O Ring 520 would sap less power from the engine

 

Has anyone tries non- O Ring and seen a worthwhile power increase?

I've had good results with JT sprockets on other bikes they are made from 7075 T6 aluminum. They are the next up to steel which is stronger. i am currently using a Supersprox aluminum inner and steel teeth outer. Which is a great sprocket but cost a bit of dough.

Steel sprockets, O-ring or X-ring chain, end of discussion.

X rings do not rob much power. If you had a road race bike I could see using a non o-ring chain.

Main thing I have been reading about using non sealed chains is that they require constant adjustment and cleaning/relubing. 

I'm a firm believer in Ironman sprockets with the Regina chain. They are light, look trick, and last forever.

DID, Sunstar. Steel. O-ring. love you long time
