Titanium K-frame Bolts
Very nice looking bolts! Whoever made those is a skilled machinist, especially if they are on a manual machine.
As a point of interest, the low average weight of a human #2 is around 450 grams.
The insoles of my shoes weight 157g.
My house keys weigh 42 grams (4 keys).
It will be interesting to see how the weight delta between TI and steel pans out.
*if* I was going to replace something external to the engine in TI it would be the exhaust system, rear end axle tubes, and axles.
Definitely nice hardware for the stock/factory appearing people.
