Titanium bolts
« on: September 13, 2020, 02:22:53 pm »
I just received these to replace the ugly Yamaha sissybar upright bolts. It didn't take half as long as the ETA said it would to get here. These are stronger than the OEM bolts and look way better. They're expensive but there's really nothing else out there that looks half decent. I got 70mm so I can cut about 8mm of threads off and have more shank. Allen heads and different lengths might be available, too.

Plus, you're adding lightness.

Believe it or not - Titanium is NOT as strong as steel.  Just lighter. 

It stands between Aluminum and Steel both in weight and strength - basically a decent compromise if weight is your primary concern, but just an expensive waste if you're looking for STRONG hardware.  Stainless would be a much better choice, but even it is not quite as strong as high-carbon steel.

The grade 5 titanium is slightly stronger than SAE grade 8 or class 10.9. Other titanium grades are not as strong but more corrosion resistant and fall between aluminum and steel in strength to weight as mentioned. The grading for titanium bolts is not the same as steel as 5 is the only grade made for strength.

I used moly and tightened the Ti bolts by hand to what I felt would be tight enough. A torque wrench showed 17 ft lb. on the left bolts and 15 on the right. Bike was on side stand and I was afraid it would be to easy to bear down on the right ones. The OEM right side bolts weren't very tight either :P. All are at about 17 now.
