Endurance motorcycles of the 80th had their charm. "Workhorse Speed Shop" created a custom, which combined the style of these motorcycles and racing bikes for short distances. The project was named "Sakura" and was created on a Yamaha XSR700 as the base. The bike will take part in the 2018 Sultans of Sprint. Brice Hennebert of Workhorse Speed Shop is the latest builder commissioned by Yamaha to create a Yard Built custom.

Sultans of Sprint is the famous race in Europe. 1/8 class races are held at major events such as Glemseck 101. One-cylinder and twin cylinder motorcycles with liquid cooling and the maximum power to weight not more than 0.65 hp. / kg can take part in the factory class.
