Congratulations although a little surprised as they still have a lot of R1S quad motor vehicle to deliver.I don't know the answer to your question but I also wanted to chime in and say that we just received an email to confirm our dual motor R1S configuration.
Nice!I got mine last night also. I am a June '21 reservation holder, with Oct-Dec '23 delivery estimate. I have not changed my configuration since Limestone became an option for color choice.
I keep looking for Shop availability, but none so far.
I am really getting excited about getting this beauty in my driveway!
