SIRES – Ski Inspired Road Evaluation System

Over the past weeks we have discussed how best to describe the roads we have been on from a motorcycling perspective. The suite of Alpine events found in the Skiing World Cup and the Winter Olympics seemed to us to provide a suitable analogy for relating efficiently what a road is like. So here goes …


Downhill (DH) – Typically a straight run at highway speeds with not a lot of deviation in the route. You can ride all day on cruise control without having to cancel.


Super G (SG) – A road with gentle wide radius curves/ sweepers. For the most part you can cruise along in cruise control in top gear and navigate the curves.


Giant Slalom (GS) – A road with tighter twisties, curves that require downshifting to 4-5 gear at times.


Slalom (S) – Tighter sweepers typically requiring gear choices from 2nd to 4th gear.

(NB: We’ll be using this system going forward to describe the roads we have had the pleasure to explore)
