The latest motorcycle accessory may leave older riders yearning for simpler, undiscovered times while the younger bikers may wonder where the Mad Map’s Harley-Davidson Map app has been all these years.

The Mad Map’s Harley-Davidson Map app (try saying that three times fast ) offers riders 975 of the best scenic rides for motorcyclists in the United States promising to make trips more memorable by taking riders off the interstates and onto two-lane ribbons of pavement.

The officially licensed H-D iPhone Map app joins the growing product line from Mad Maps which includes printed paper maps, GPS downloads and mobile applications. For a one-time charge of $4.99, each detailed map is less than one penny.

Examples of downloadable ride maps available in the Harley-Davidson Map app include:

Canyon Tour – Winding through the canyons of South Dakota's Black Hills, this tour is ideal for anyone traveling to Sturgis.

To Big Sur, With Love — Explore the best the California Coast has to offer and stop for lunch and an awe-inspiring view at Nepenthe.

Because it's built with Harley riders in mind, the app lets customers quickly and easily find the nearest Harley-Davidson dealership in case they want to stop while on the road.

In addition, it has a Best Western hotels locator so riders can take advantage of the chain's discounted Harley-Davidson rate and Rider-Friendly hotel program, which offers special amenities for motorcycle riders. Riders can also sign up for Best Western Ride Rewards, a rewards program for Harley-Davidson enthusiasts.

MAD Maps develops its maps with the help of local riders who know the back roads like the back of their hand. This enables the maps to highlight the best scenic roads and the cool stops along the way - from natural wonders to rock 'n' roll roadhouses.

"Our scouts are our product," said MAD Maps Founder Jennifer Lefferts, "Instead of relying on satellites in the sky, our development depends on real people on the ground."
