Wow, had to read that a few times... sucks getting old. Thanks for putting that together. Effectively, it looks like they streamlined the line-up... which makes sense.It's a bit more complex than that - in 2018 there were (ignoring the LRH) 4 models: A2 S, S, R and RS. The "A2 S" is a smaller capacity bike restricted for a European A2 licence (less than 35kW).
For the 2020 range, there's S, R and RS. However, the S is equivalent to the A2 S - so if you ignore the 660cc bikes, they've gone from three 765 models, S, R and RS to two, R and RS. The 2020 R effectively sits between the 2018 S and R, both in price and equipment.
The 2018 S had LCD, R and RS had TFT. The 2020 R has LCD, the RS has TFT.
The R models all have the red subframe, and the black/red paint looks great. It's not Matt black - the matt colour for the R is Matt Silver Ice (grey/red).
I remember the R models had/have the red subframe. I like my silver subframe, but I know the red is actually sought after by some people. I didn't realize they did a non-matte black/red. The last time I was at the dealer (before the virus hit), all they had were RS models.
