If you're fitting this rad guard to a 2023 model, you need to make the following alterations as a previous buyer commented on.
Firstly, you need to trim the inside of the plastic side radiator panels to remove the small tongue shaped extrusions (4 off) as this makes contact with the radiator guard corner bracket, so they're impossible to fit.
Secondly, you'll have to use a dremel or a fine file to remove a small portion of the corner top brackets as this digs in to the plastic side panel when refitting these panels. A bit of a pain but its doable. Evotech, please note this needs altering for the latest model R1250R 2023 onwards.
