NOTE: full, turn-by-turn GPS DH NorCal App now also available! The GPS app also includes everything this base app contains (explained below). Make sure you get the correct app you want.
The finest curated collection of NorCal motorcycle roads that gives you something no other book, map, website, forum, GPS unit or app can: comprehensive knowledge of where the best roads are and what they’re like. Our 34,000 mi (54,000 km) of research riding in NorCal guarantees it.
"A Godsend! Riders spend hours searching for opinions and secret roads that can all be found at their fingertips in mere seconds here."
Ride like a local instead of a tourist on the best roads in NorCal that ARE the destination, whether you're 100 or 10,000 mi from home.
Our (T)otal (I)ntegrated (R)oad (E)valuation (S)ystem rates paved roads numerically from a street motorcyclist’s unique perspective. The points total determines a road’s rating out of 100. With this the road earns its DH number, its ranking among NorCal’s Destination Highways.
“I am a highway engineer by education. TIRES is a great way to evaluate roads specifically for characteristics we motorcyclists desire most.”
What about those roads that are not quite DHs but worth riding if you happen to be in the neighborhood? DH NorCal also guides you to the Twisted Edges (TEs), those subsidiary side roads you tend to pass up.
Riders spend much of their time “riding like a tourist” on major highways, wondering where all the good roads are and just LOOKing at all the unknown DHs & TEs that slide past their shoulder all day long. With DH NorCal, not any more.
122 onboard DH NorCal maps, plus “big picture” Companion Map (for discount on actual 39 x 27 inch synthetic CM, email us from app).
