Are the front disc bolts M6x20mm & the rear M8X25mm? & what pitch? I want to install my ABM rotors & Tasty Nuts (under fjr) show a set of 10 for the front. Should be a set of 12. Also under fjr they show sprocket nuts., so if they don't know it's a shaft drive or how many bolts on the front, need to know if they got the sizes correct.

 
SP, I don't know about the rears. The 12 rotar retaining bolts for the fromt are:

Yamaha P/N 90109-064G6

M6X25 the pitch is 1.0 CAUTION!! THEASE ARE SHOLDERED BOLTS WITH BROADER HEADS THAN NORMAL. The sholder extends 11 mm below the head and is 8 mm diamater. Conservitevly suggest high level of caution when ordering. 60+% of breaking depends on thease little round thingies.

 
Thanks, took me a couple of days, but I've figured out the rear is the same as the fronts. Which I believe is M6 x 20mm length shouldered bolt. I'll be getting them in aircraft-grade titanium, which are designed to replace bolts in stress areas and reduce unsprung weight.
