Chain/sprocket time...looking for suggestions

[Tinken]

So what am I getting besides a lighter weight for 3-times the cost? Is the aluminum stronger than a steel one? does the steel one make that much difference in unsprung weight? Would I even notice it?

Dirt Tricks Rear Sprockets are made of heat treated, nickel/chrome plated, chrome-molly steel that is 2.5 times stronger than stainless steel; 3 times stronger than 7075 aluminum.

Ah, wow...they look like aluminum. Guess I didn't read the specs.

I know them from the cam chain tensioner I got for my KTM.

How much stronger than regular steel sprockets? Like the JT's? What exactly is the weight difference?

They are lots lighter, but that's not why I am recommending them. They are super strong and they just don't fail.

Those Dirt Tricks sprockets probably have similar lifetime to most other steel sprockets, but are quite a bit lighter; decide if that matters to you. On a 610/630, maybe not...

I am always skeptical of sprockets claiming to be "X times stronger than aluminum!" Stronger can mean a lot of things, and they don't all translate to increased wear life.

I would definitely run one of those on my WR, lightness of an aluminum sprocket with the wear of a steel.

I hadn't thought of putting my new take-off 15 back on...geez. I can get a 45-46 rear and a little more chain. Duh. But the roller guide probly won't work then?

Buddy w/ 15/50 had the stock guide until recently upgrading to BRP.

Thanks Bob, that helps. The 14-42 tends to run the chain against the top of the chain block anyway. In fact I had to grind some away to keep it from rubbing all the time.
I figured there was probably room to accommodate the larger sprockets.

So let's see if my math is correct...
If I liked 14-42 then 15-45 would be the same, and a tooth or two lower would be a 46 or 47, right? I think I'll go 46 if I can get one. How many links? Better just get 120 and cut to size eh?

Dirt tricks makes a 46 rear

The DirtTricks sprockets for husky list every model EXCEPT the 630...same as the 610?

I might go that way. Their chain and a rear sprocket is $240. OUCH. Does anyone have a discount code? Maybe a ADVrider discount?

Ch10 is the ZipTy discount, works for dirt tricks ironman sprockets at the ziptyracing.com website.

When I ordered Nate gave me 10% off without even asking. Nice guy and a great product.

Ch10 = "This coupon does not exist"

I've worked with Nate before. I could just give him a call.

 

[Tinken]

I just used CH10 at our website, it and it worked, no problem.

Ah...I was at dirttricks.com.

Thanks!

I asked Ty the difference between a JT sprocket and a DirtTricks. He said they are both steel, but the DirtTricks is tool steel and will last much longer.

You and TY are for sure right that they are hard and tough but I wanted to mention that I stopped using the Dirt Tricks CS sprockets (advertised as the same hardness as punch press dies) because they are so hard and there have been cases of excessive CS wear, they may be as hard or harder than some CSs. I'd rather the CS sprocket wears more than the CS and change it when the spline gets sloppy..
The Dirt Tricks laser cut rear sprockets are very good, barely heavier than AL, really nice to look at and wear forever when run with a good X ringchain and CS sprocket.
