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 pair of R&G Footrest Blanking Plate has been specially designed to cover/protect both the left and right-hand sides of the Honda CBR1000RR '17-'19

R&G Footrest Blanking Plates are easy to install, simply screwing into place in place of the rear pillion pegs, covering those otherwise exposed sub-frame holes, that if left uncovered could result in corrosion of the frame/subframe from dirt, water and debris buildup.

Finished in Black powder coat and with an 'R&G' logo.

Please note: Picture is of 3D printed prototype and as such for illustration purposes only, the actual product will be made from Aluminium, Black powder coated and then Tampo printed with an R&G logo.
