4 x Stainless Steel Studs and Flange Nuts.
To fit all RSV Mille Models with V twin engine
 
If you are adding race headers or just changing them, it is the perfect time to upgrade the studs to reduce future problems
The studs are the upgraded version with the pre machined hexagon for easy installation.
And the flanges are serrated to stop vibrational loosening.
They will not rust and continue to provide good service for years to come.
