For your 2021 RMAX2, the taller doors should fit, but it depends on whether you have the standard cab or any special edition package. Yamaha’s “tall” doors are designed for the same frame as the short doors, so installation is generally straightforward.

 

Thank you, now I need the P/N! And I made a mistake, myX2 is a '22. It is not a special edition or anything. It came with a hardtop and short doors and I installed an Oem rear window, front plexiglas windshield and mirrors. The outside mirrors will likely have to be taken off.
