Dirt bike chain on ninja?

The only shop around here that supports anything 2 wheels is a dirt bike shop.

they said they have 520/180 MX chains so id have to cut it down. Are MX chains even remotely safe?

I've been into motorcycles for almost 40 years and I didn't know there was such a thing as a dirt bike chain or a street chain. A 520 X-ring chain is a 520 X-ring chain as far as I know (for example).

On the other hand, you can buy a good chain at a good price from tons of Internet suppliers and have it the correct length and delivered to your house in a couple days. I like RK chains for their cost and quality.

Chain is chain is chain is chain. As long as it's the right pitch, IE 520, it will work. If it's too long, you'll need a tool to shorten it and press it apart. Cheap at Cycle Gear.

MX chain typically isn't sealed with o-rings, though. Won't last as long if you're not thorough and consistent with maintenance.

O-ring or X-ring are better as they are sealed but non o-ring chain works too.

Thanks for the input. I just wanted to make sure chains werent rated differently for their speed, torque stress, etc. In my line of work everything is designed to meet different specs including chains lol. Didn't know if the outside world was the same or not haha.

Well, considering the Ninja 250 has the same or less power than a 250 four stroke dirt bike and even some 125 two strokes, I'd say you're safe.

Just check if it's o-ring or not. Most of the time on the street you will want an o-ring chain. The o-rings seal the rollers and keep the lube in. You still need to clean and lube the chain, but that's more for the contact areas and to keep the side plates from rusting.

Non-o-ring chains are a lot cheaper, have less friction, but don't usually last as long. Chains are more of an expendable item for dirt bikes, so they don't worry about long-term durability.

All correct, except the o-rings seal the main load bearing joints, the pins and bushings inside the chain, not the rollers, which remain unsealed. Keeping the chain lubed, as you said, prevents rust, and lubricates the contact areas. It also lubricates the rollers and keeps the O-rings sliding around instead of getting chewed up on dry steel.

You can also order chains off the internet. I generally get them from Amazon, I run EK O-ring chains that seem to last longer. Here's one on Amazon now for $45.74:

https://www.amazon.com/EK-Chain-006G...+Chain+520+sro

Add four bucks and you have free shipping, too.

I ran a non-o-ring chain once. It lasted me 1,500 miles, even with cleaning/lubing every 100 miles. I usually get 20K-25K out of a chain, so, paying the extra for a proper x-ring chain pays off very quickly! You could get one with a clipped master link and install it yourself. (I put a bit of safety wire underneath/around the clip and haven't every lost a master link.

for a track bike if you don't want to go to a smaller pitch chain, a non o-ring MX race chain can be a great 520 option

for a street bike, buy a sealed chain

I used an non-o-ring chain once. It rusted and stretched out way too fast despite very frequent lubing. I would not get less than an o-ring chain again.
