Yonex AS50 Speed 2

Natural feather balls from Yonex are made from feathers sourced from Chinese geese, which are by-products of the food industry. The five different products vary only in quality, indicated by a number; the higher the number, the smoother the ball flies and the longer it lasts. The AS-40 and AS-50 shuttlecocks are approved by Swiss Badminton for all tournaments and interclub championships in Switzerland. The AS-30 is approved for the 3rd to 5th league of the Interclub Championships and is also recognized as a first-class training ball, popular among unlicensed players. The AS-30 is the bestseller in the range of natural feather balls. The AS-20 and AS-10 are excellent shuttlecocks often used as training balls in clubs. Even hobby players increasingly prefer shuttlecocks with real feathers, as they provide a better playing feel and a richer sound upon impact.

Yonex shuttles are utilized in the majority of Grand Prix tournaments, all World Championships, and Olympic Games. They are the standard in both elite and recreational sports, making Yonex shuttlecocks the best-selling in the world.

The AS-10 and AS-20 are available only in Speed 3. The AS-30, AS-40, and AS-50 are available in Speeds 2 and 3, with AS-50 also offered in Speed 1. Typically, Speed 3 is used in Switzerland, but Speed 2 is becoming increasingly common. Speed 1 is best suited for regions like the Jura or Engadin, where other shuttles may fly beyond the field. In badminton, the speed of the shuttle is determined by the rules or the referee, if applicable, and is only adjusted for external geographical or meteorological factors such as temperature and humidity. The level of play or player preferences do not influence this regulation. However, at lower levels, slower shuttles are often preferred for easier control, while faster shuttles allow for hitting from baseline to baseline.
