My 2007 GS500F which I bought just a little bit ago I noticed that there's no end caps in the grips now it's starting to just look like a rusty hole I can't believe the Japanese would leave these out for weight haha honestly do they come with an Caps or did someone like the previous owner pop them off , they are starting to look kind of nasty the rest of the bike looks brand new it kind of sticks out like a sore thumb
The F model did indeed come with bar ends from the factory. Its likely they were removed by the PO for some reason (damaged by tip-over, bars replaced and no bar ends installed, etc.). You can purchase new ones and install them. Literally any 7/8" bar ends will fit. I have these: https://www.cyclegear.com/parts/speedmetal-milled-bar-ends
Those bar ends on the GS take some of the vibration out of the bars when properly adjusted, wouldn't leave home without them. Tighten them up once and see how it feels.
Thanks for the reply I never really looked at it picture of a GS500F and notice that the hand grips are really extensions I thought they were just caps at popped in and we're flush with the end of the handle now I know what that thing is floating around one of the handlebar ends it's what one of the original grip extension screwed into
