Yamaha R1 titanium exhaust studs with 7075 alloy nuts
I’ve made a set of titanium exhaust studs for a Yamaha R1 and 7075 alloy nuts to go with them. The studs are M8 thread into the head but M7 to take the nuts. The nuts are Surteck 650 coated for corrosion protection.
The studs weren’t the easiest things in the world to make, there is very little plain shank between the two threads so very little to hold onto once one thread was cut. But we managed.
