I had the chance to do both the black spur (with pillion) and some riding in South Australia the week before to do a comparison. All I can say is the spur is walk in the park in comparison in terms of technical difficulty! In terms of access (time to go and hit the twisties) in Adelaide, I take my hat off to you. The roads, whilst less graded and wide, are some of the best I have ever ridden. I will show the location of what I think are the best short runs available. 1. Mitcham to Clarendon Map 1 More hairpins than you can throw a stick at, all allowing you to get some serious leg down + back end slipping no less than eight 180 degree + turns. Advantage: bugger all traffic Downside: narrow roads means make a mistake and your airborne + occasional road debris 2. Victor Harbour to Cape Jervis Map 2 This run is hair-raising with multiple switch backs, but heaps of rough surfaces. Advantage: You get 30 km of pure twisties. Little traffic. Downside: bumps, cattle, road debris 3. Crafers to bridgewater round robin Map 3 What can I say. In short, after coming back and hitting reefton and the spur. Seemed like a beautiful country cruise in comparison. Ride safe!
