I think I can answer these ...
A: Whether RT-S or other, the front suspension guidelines on Page 47 of the owners manual should be followed. On the RT-S, the rear suspenion adjustment is electric, which makes things a bit easier; howerver, I do see why you're asking the question regarding the front suspension, and hopefully, you don't have to do it too often. The front suspension adjustment is different for a single rider depending on weight, then again for that rider with a passenger depending on weight; then again for the rider, passenger and cargo. The cam adjustment setting range from 1-5.
