The world is full of bike-friendly locations--spots with big curves,  little to no traffic and boundless adventure. Motorcycle tourism can be a  great way to indulge your riding habit and see some of the most  beautiful places on the planet.
Vietnam
Starting off our list of the world's 10 most stunning locales for  ramping up your riding skill is Vietnam. Due to import taxes of 90%,  it's rare to find luxury motorcycles for hire there. But with the  national speed limit hovering at 60 kph (80 kph on a few major  highways), you'll hardly need anything hardier than the ubiquitous  Minsks (Russian motorbikes) or Honda 175 cc's to tackle the otherworldly  mountain terrain of terraced rice paddies and stilt house villages in  Vietnam's north. Hanoi-based Offroad Vietnam arranges custom tours for  groups or individuals. Homestays with local Hmong people add cultural  immersion to the equation.
The Lot Region, France
For some of France's most wide open roads and diverse riding terrain,  the Lot region in the country's wild southwest is a motorcycle-lover's  must. Highlights of the region include the fairytale hilltop village of  Rocamadour, the Millau Viaduct (the world's highest vehicular bridge)  and the Gorges du Tarn--a dramatic limestone gorge with hairpin turns  and steep descents. At Bikers-Lot--a bike-friendly bed and breakfast run  by a British couple in the small village of Latronquiere--multi-course  meals and unlimited guided tours of the region are included in the room  rate (arrive on your own bike or rent one in Toulouse or Rodez).
Gobi Desert, Mongolia
For utter solitude in the land of Genghis Khan, no place compares  with the isolation and exoticism of a motorcycle trek in Mongolia's Gobi  Desert. Ulaanbaatar-based Tenuun Tour Co., Ltd supplies riders with  motorbikes and a support vehicle complete with a mechanic and  all-important gas, food and sleeping provisions. The ride-through views  encompass sand dunes, snow-capped mountains, grasslands, volcanic lakes  and wide-open desert steppes. Homestays with nomadic families in yurts  can also be arranged.

Rajasthan, India
Join a tour group or depart solo from Delhi and head southeast to  reach the land of the former Maharajas. The riding terrain is fairly  flat and low-key, but summertime ventures should be avoided as high  temperatures threaten to melt your tires to the asphalt. Texas-based  tour operator Moto Discovery offers 14-day trips through Rajasthan that  include side trips for tiger viewing at Ranthambhore Tiger Reserve as  well as an overnight in Agra to see the Taj Mahal. Prefer to go solo?  Motorcycle rentals can easily be arranged in myriad shops in Delhi.
New Zealand
Forget bungee jumping and jet boat rides. The biggest thrill in the  land of the long white cloud is taking to its lightly trafficked roads  on a motorcycle tour or solo mission (top-notch bikes are available for  rent in major cities on the north and south islands). Edelweiss Bike  Travel offers 14-day jaunts of up to 2,430 miles, leaving from  Christchurch on the South Island and circumnavigating the country's  highlights before finishing in Auckland on the North Island. Roads are  mostly of the tight-gripping-asphalt variety and suitable for beginner  riders 
Tierra del Fuego, Chile and Argentina
Make the end of the world your mission and ride through Argentina and  Chile to the Tierra del Fuego. Seventeen-day forays with  California-based Admo-Tours cover 2,734 miles, with a late-model BMW  bike as your chariot from the town of Osorno, Chile, to Argentina's  Atlantic coast. Ferry across the Straits of Magellan to Tierra del Fuego  and get back on your bike to catch the Pan American highway and cruise  onward to Ushuaia, the world's southernmost city.
Nepal to Tibet
Two-wheeled access to the highest mountains on the planet is the  chief appeal of a motorcycle adventure from Nepal to Tibet. Himalayan  Roadrunners Ltd. offers 12-day tours departing Katmandu for the "rooftop  of the world" (or very close, anyway), with 17,000-foot mountain passes  on the itinerary as you ride toward the foot of Mount Everest. Yes,  altitude sickness can be an issue--this ride is the motorcycle trip of a  lifetime, but not for the faint of heart.
Bali, Indonesia
Cruise the island of the gods on the gnarliest bike of mere  mortals--a Harley-Davidson--with Bali-based operator, Island Biker  Tours. Day trips make up the bulk of the company's offerings, with your  choice of coastal routes or inland tours that take you past volcanic hot  spots and the artisan village of Ubud. Longer forays onto the  neighboring islands of Lombok and Sumbawa can also be arranged.
South Africa
See the best of South Africa and Swaziland with Ayres Adventures  during a 17-day coastal tour from Cape Town to Johannesburg. Detours to a  game lodge in the Klein Karoo, a safari at Kruger National Park and a  visit to a Zulu community keep things interesting when you're not  riding.
Tuscany, Italy
Ride a Ducati in the revered motorbike's homeland during a seven-day  tour of Tuscany with Ducati Tours. Italy is notorious for its fanatic  drivers, but you'll avoid the motorway entirely as you leave Pisa behind  and head for lonely country roads in the Chianti region and the rolling  hills of the Tuscan and Umbrian countryside.
