First up is a pair of what look like cable/brake hose guides that bolt to something (a fork leg?). Please see first two photos.

Second is a collar/spacer with a little (locating?) section cut out of it. Internal diameter is just over 20mm, external diameter is just under 33mm and width is 11.25mm. Please see last three photos.

All of these came to me in a job lot of supposedly Yamaha R5 parts, but they could easily be random "rogue" parts and not necessarily even Yamaha.

Many thanks.

     

I will guess the collar is for the kick start assembly, wild guess lol. 

Bang on! 

Not a surprise, as there were some other random kick start parts there as well.

Thanks very much.
