been in simlar position buying bolts recently......one thing i learned, be aware not all bolts are made equal, they all have different properties and will have been chosen for their purpose when the bike was put together, i have in the past purchased bolts that were not OEM but i made sure they were the same material and grade i.e. 8.8, 12.9 A2, etc....there are international standards the allow you to usually detemrine the type and grade of a threaded fastner....

When it comes to parts like engine mount bolts and suspension linkages i would be tending to side with OEM, i don't know enought about the material physics and properties to make the correct informed decisions....but thats just me - i am a little OTT sometimes!
