Once you have removed the pillion footrests, fill the void left behind and cover those otherwise exposed holes in the sub-frame with an R&G blanking plate. 

This Footrest Blanking Plate has been specially designed to cover/protect the Yamaha XSR900 '22- models (Single, central piece). 

R&G Footrest Blanking Plates are easy to install, simply screwing into place in place of the rear pillion pegs, covering those otherwise exposed subframe holes, that if left uncovered could result in corrosion of the frame/sub frame from dirt, water and debris buildup. This specific Footrest Blanking Plate incorporates a mount for the remote pre-load adjuster on the left side of the bike.

Finished in Black powdercoat and with a white 'R&G' logo.
