The 'R' version allows the more cost-concious racer to go racing with the main features that made the 410 so popular.
If you work out a retail price for all the bits that are not included on the R and then add them to the price, you'll be far and above the price of a 410.
As for performance difference, the 410 is the pinnacle of the range so it will give you every last ounce of performance. The 410R will give you the lions share of this performance and leave you to decide if you need to upgrade any parts.
You now have a choice....
Money in pocket or money on track
