Chains - Rites and Wrongs

No you don't, that's the placebo effect.

(unless you changed gearing, than that is what you felt.)

Your right to one extent, nothing can be felt in the acceleration or breaking, what can be felt is that weight spinning in the twisty stuff, granted nothing near as much as tires or wheels.
 
Oh, I absolutely know the weight of the tire makes a difference. (y)

(but that's lbs at the circumference, and not a few ounces on a sprocket)
 
Ok, so back to chains. I'm surprised that no chain co has built a Ti chain. Chains weigh a bunch, compared to belts. (Yes, I know belts for final drive for HD seem to work well.)
It seems to me that motorcyclists/tinkerers are not afraid to spend $$ to lose weight on their bikes. BST wheels are a large weight reduction.
I dunno, maybe a graphene chain, or carbon fibre...
Dunno how long they'd last, but there's gotta be something that's lighter than steel/aluminum. That's strong enough...
 
Going back to the post from Vintage Veloce, an ERT3 weight 3.58 lbs./ 120 links and has 8300 lbs tensilstrength vs. the titanium @ 3.6lbs. & 9000 tensil. With the normal going rates, I would be confident that with exactly the same maintenance routine you would replace the moto-x chain, often, and still save the moneyz in the long run vs. titanium.

An Enuma Three D in Chrome or a RK Black Scale look cooler anywayz. 😎

I think MotoGP bikes have an abundance of power! But didn't the 125s use no-ring chains?
And failure might be a bigger concern than the last half horsepower.
Going no-ring used to be a pretty common race bike mod. I'm all for it with a well maintained and frequently replaced chain.
Interesting article from a couple years back...

Ask MO Anything: MotoGP Drive Chain?

A readers asks about the maximum mileage of MotoGP drive chains and whether they use O-rings or require special lubrication.

Just surprised they don't use titanium chains, even while they do use titanium sprockets. Apparently, not needed or doesn't work...

I'm looking forward to the new Regina "maintenance free" chain
 
Looks like Moto3 uses the DID 415ERZ (no ring). Looks like the off road chains often have no ring either. Fascinating.
I run a x-ring on my KTM dirt bike though.
 
I was talking with someone about DID chains and the topic was 520 ERS vs 520 ERT tensil strength. The conclusion was that with modern chains its less of a question of a catastrophic failure (chain rip), and more a question of the duration of use before wear limits are exceded.

In theory, with equal chains, more tensile will wear longer on the same bike under the same conditions.
 
Yeah that makes sense, and of course also depends on the wear of the sprockets. If your sprockets wear (especially the front) I have the feeling the chain has no choice but to follow that pattern...
