Motorcycle brake calipers- titanium bolts?

[ssray]

I've just fitted a radial caliper conversion to my old zzr1100.
Reading about bolts on another thread I thought I'd check if they are ok in this situation.
The ti bolts are the ones going through the caliper to the bracket, not the ones holding the two halves of the caliper together.
They have now been shortened
