This Website is the most comprehensive assemblage of information in the world on factory turbocharged motorcycles.

It is dedicated to the dozens of people who selflessly volunteered to benefit the association's members, the hundreds of Turbo Rally participants who always supplied interesting entertainment whenever and wherever Turbos gathered, and to the thousands of worldwide Turbo owners and enthusiasts who continue to express an interest in these rare and unique motorcycles.

Turbo Tim says, "Ride 'em – don't hide 'em!"

"Several times in the past 25 years I’ve considered replacing the Turbo, but I enjoy its rarity and I can’t find another motorcycle with the wind protection, ability to comfortably cover 500 miles of two-lane roads in a day, and the addictive “stronger as it goes faster” power of a turbocharged engine. Even today, the Yamaha Turbo offers a thrilling ride every time you twist the throttle - and have the guts to hold it there." Winding Road Motorcycle Times (March-April '07).
