2021 OneRR 300 - any serial issues?

[bikerpet]

I'm looking at a used 2021 RR 300 and just wondering if there are any serial issues with this model?

I see that there were a few changes to the 2022 model:

• New steering angle
• New sump guard rubber
• Improved airbox
• New regulator connector
• New exhaust support
• New shock ball joint
• Updated crankcases
• Revised flywheel

And again for the 2023 model:

• New swingarm
• New sump guard
• Improved airbox (again)
• Improved chain tensioner
• New CDI mapping

I don't know if any of these are particularly significant, but the crankcase sounds like it could be, it seems like the cast crankcase was new for '21 and a revision in '22 sounds like there might have been problems.

Thanks
