rear chain sprocket

[gianco80]

hi!
today a changed final drive,
i see that the rear sprocket, on this my 2021 is installed with flat side on left,

on previous xr i had(my 2016)
instead, flat side on rigth, toward wheel.

very strange.

on your bike how is fitted?

Generally - the writing is on the outside of any parts.

How do the two compare on offset?

[gianco80]

yes i also was thinking so.
but on k69, i see it is fitted other way….

anyone could please upload a photo of own rear sprocket?


offset is identical new-vs-old sprocket i changed


flat side out:

I’ve checked my own photos of sprockets on my bike after each change and also library photos online-  and they all show the stepped/writing side as being on the outside.

I have changed sprockets twice, I think - and fitted the rear sprockets as I have described, and ‘probably’ checked the orientation of the first one (OEM) before removing.

You’ve changed the rear sprockets twice on a K69, what mileage are you doing?

Mine is a 2016 Euro3 model.  Done 30,000 miles now and it’s on 3rd chain? (Inc the original).

Why?  Because they only cost around £120 including sprockets.
