Got some titanium caliper bolts for the Versys they weigh 17 grams each. Not sure what the OEM weigh I forgot to get them back.
I wasn't after Ti particularly it was all I could get apart from the crappy OEM bolts which I chewed the heads off trying to get them out.
These should last forever (well the life of the bike). It was a big week for the little Versys (fork seals, new Bridgestone T-30 Evo's, lower suspension, new sidestand, brake fluid change and engine oil and filter change).
On to another 7 years of pleasurable riding on a brilliant Kawasaki motorcycle.
