BMW have re-invented the chain. It doesn't need any lube and will never need any adjustment... yeah right!

I guess they had to do something with their reputation of final drive failure on the shafties.

A chain that BMW says will last forever ?
Tell that to owners of their N47 engined cars.

I have a car with the N14 engine, it has the same problems as the N47

I have some Snake Oil for sale and some gold/niobium/dysprosium HDMI leads for ultimate picture quality as well if your interested.

If it doesn't need lubricating, won't wear out and won't need adjusting why are there adjustment carriers on the swinging arm in the picture?

Interesting concept though, I wonder how much, if any, improvement on normal chains it will be.

It's a £100 option on the S1000XR/S.

If you don't pay the extra £100, you'll need those adjusters.

Ah, thanks.

Will that not just eat sprockets :ugeek:

I also wondered what the effect of not using lube would have on the sprockets.

Unless you do silly miles (and I used to as a courier ) the sprockets wear out mostly because the chain stretches and no longer fits neatly in the 'valleys' of the teeth but rides up the side - that's what creates the 'breaking wave' effect on a very worn sprocket.

The main problem with X ring chains is the X ring deteriorating and letting the sealed-in grease escape - then the internal faces wear very rapidly. If these synthetic diamond-coated wearing surfaces were really that hard and friction free, they wouldn't need the grease, nor the X rings.

Might have been easier, and cheaper, to make the chains enclosed. Though that might have ruined the look they were after for their bikes.

When I was a kid, chains were made from spaghetti.

Modern chains are much better. All my GSXR1000s lived on track, thrashed many times harder than any road bike. But only needed adjusting every few thousand miles .
I only lubed it when I fit a new tyre which was around 750 miles.

The chain on my Bandit is older than 4 of my kids. It's been on the bike 15 years and really hasn't been adjusted much, I remember I bought it for my GSXR so it was stupidly expensive but it was worth every penny.
