Metro Phoenix straightaways can be mind-numbing for the motorcyclist, causing us to crave any kind of handlebar action more interesting than a U-turn. Motoring out on our favorite longer rides, like to Tortilla Flat or Prescott, involves about an hour of arrow-straight freeway riding from our central Valley homestead before hitting any twisties. Going to South Mountain's summit, the fun starts much sooner. Easily accessible from much of the Valley, the entrance to the 11,000-acre park can be found by simply driving south on Central Avenue toward South Mountain. Soon enough, you're putting your bike through some paces with some nice back-and-forth driving. Watch out for gravel on the road, and mind the speed limit. There's a YouTube video out there featuring a guy taking a dirt dive from missing a curve — you don't want to provide a sequel. The lower speed limit (25 mph, 15 around blind curves) and treacherous cliffs make this a fun place for riders who feel the need for safety more than speed. Take the road up to Dobbins Lookout, or all the way up to the TV towers. It's a great place for improving beginner motorcycle skills or chasing away the boredom of the street grid.
