Got these in as Genuine Yamha ones are quite a lot of money :-(

They are Zinc plated serrated flanged nuts. Not as long as the originals, and not as good, but a cheap alternative. Just thought I would give owners an option. :-)

Come as a pair.

8mm thread Exhaust Studs x2 

The TTR studs are very exposed and prone to rusting solid resulting in them breaking or the thread stripping when removing their nuts. These long studs are the best replacements I have been able to find for the originals.

We sell a Motion Pro stud installer tool in the shop that makes replacing these studs a doddle.
