Spooky discovery

So I've just finished replacing my chain and sprockets with a DID ZVMX2 525 and Hyperlite RSX front and rear in OEM sizes. When I was taking off the original and put a wrench on the nut for the front sprocket after flattening the safety washer, it spun with no force at all. It was on hand tight, and the only thing that had to be holding it on was the safety washer. If you don't know, it is supposed to be at 125nm. That's tighter than the rear axle nut at 100. I bought the bike from a guy and don't have reason to think he had ever changed the chain or sprockets given their condition.

Wow.

Routine maintenance reveals non-routine conditions.

My 2018 was the same way, and I bought it with 3000 miles on it,so pretty sure no one was there before me.

Interesting. That raises the likelihood that some make it out of the factory this way. I wonder if anyone else has found this true on their bikes?

Actually now that you mention it it was proper loose on windy's XR when we did the chain and sprockets on that, that said fronts were definitely touched on that, it had a 16T front if I recall correctly.

Correct, on both counts..

Will be changing my chain and sprockets at the end of the month (originals at 21,500 miles), will look for front nut tightness

Yeah, I'm curious. I almost missed having to wrestle with getting that nut off. Funny thing about it is that the darn nut is designed to not fully thread. Meaning, when fully threaded on there are still a lot of threads left sticking out. It threw me off and made me nervous but I checked the photograph in the repair manual and that everything was seated properly. Funny design I couldn't see a reason for.
