The other information is correct,  but the R is NOT the speed rating,  it IS indicating a Radial tyre constructon. The R in the middle of the service description refers to it's construction type.
The load / speed index appears elsewhere on the tyre.
Continental know which tyre that they make works best with this bike, so follow their advice on the size for the best performance. The original equipment tyre must not have been a Continental, and they found that that size worked best for the tyre that they make.
