The locking tab didn’t provide proper action resulting in nut spinning off with locking tab

Fit my YZF600R perfectly. I've gone through 3 of these and this is the first one that didn't fall off. Use high temp lock tight and an impact driver.

Bought this in hopes it would work for my R6, and it did perfectly. For anybody looking for a sprocket nut, this will be perfect. Same size as OEM and includes the washer.

I needed to replace my sprockets and OEM is not just hard to find for my 1995 Yamaha FZR 1000, but the cost is extremely high and usually comes from an overseas dealer. This set was the ticket for the job? Quality, well made, and to me just as good as OEM if not better, especially the tabs tabs versus having to bend a round OEM washer (better contact and anti-back off properties on this one).RECOMMEND!!!
