B-Series B 6500 I has isometric head for larger hitting area. Similar to the B-4000, the Yonex B-6500I racket is composed of aluminum head and shaft from steel. The racket is pre-strung with durable string and tight tension. Excellent racket for recreational, beginner, physical education class, schools, colleges, and community center use. Be noted that manufacturer's warranty will not apply for Yonex B-Series Badminton Rackets.
The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.
