The 2021 s1000rr racing red livery is done for Zen-Imogen’s s1000rr mod. I used the template which is provided by the author and made this livery.
1. Extract s1k_sign_5 into any desired directory, or simply, put it in your desktop
2. Using OpenIV, go to : mods/update/x64/dlcpacks/s1000rr/dlc.rpf/x64/vehicles.rpf/
3. You should be able to find s1000rr.ytd then right click, and select edit
4. A new window will pop up, select import, then choose s1k_sign_5 to add
5. Don’t forget to save before exiting.
