Question upgrade for stock 415 chain?

after all my posts helping others, it's finally time for me to ask for some help.

i've got the stock 415 chain and i want something better. i hate the way the rollers are loose and poorly fitted, the slack and stretch, and just the general lousy quality of it. my chain snapped the other day, without snagging on anything, it just ripped apart. i put another chain on, the same kind from my old bike, because my snapped chain sat in the street getting run over by 20 cars before i could retrieve it, and it was all scarred up.

the chain i put on, while the same size, fits differently. there's more slack, which i could attribute to stretch, but more likely, just bad workmanship.

i've read about upgrades in other posts, but i can't find them now.

i notice the 415 has slack on the drive sprocket (engine) so a slightly skinnier one would work, but not a bicycle one.

i plan on upgrading to steel motorcycle sprockets, because i don't like the way the aluminum aftermarket ones get chewed up too quickly. the forces of my motor running at top speed all day long are too much for soft aluminum. plus, one derailment and the teeth get eaten. already destroyed a 28 tooth because of that.

so i'm looking for suggestions from people who've upgraded to a KMC or something, where you got it, how it fits, and any other pros and cons.

thanks.

415HD= heavy duty chain. If you are changing sprockets check your pitch and width. Not sure how much of a problem it is when sprockets are different p&w but have to think there is some.
How did you like the 28T ?

I second the #41 roller chain. My original chain broke about 1 month into my riding career. I use the industrial chain now. Much stronger and better made. Tractor Supply carries it if there is one near you. You might also try the big box home supply stores like Home Depot or Lowe's.

$13 at Northern tool..

Drive Chain #41 | Chains + Sprockets | Northern Tool + Equipment

Of course, if you do a google search for 415 chain the sky is the limit on quality. You can go from this basic KTM replacement chain:

http://www.ktm-parts.com/mm5/merchan...de=45110165104

All the way up to:

RK Heavy-Duty GB 415 HR (Gold Color) Chain - Chains - Solo Moto Parts

And everything in between.

The 41 is a bit beefier in width and construction, but TBH I think it crazy overkill. If ya could find a higher quality 415 that'd be the way to go I think, particularly if yer tight on clearances. It's the poor quality of the kit supplied ones that's a problem, I'm pretty sure even a good BMX chain would be more than strong enough - lookit alla shiftkits out there

Also I believe 415 = metric and 41 = standard.

I think that the #41 is the way to go. It's a lot more durable, seems to ride on the sprocket smoother, fits better, and you get alot more chain for the money. In the pics below, you can see the diff. the one on the left is the 415 from dax and on the right is #41 from TSC.This is about how much chain you get from the kit (415) And this is how much chain you get at TSC for about the same price
