NEW Color for 2009
The Yonex Muscle Power 2 Junior (MP2Jr) 2009 badminton racket is similar to the Isometric 22 Junior (Iso22JR) badminton racket. The racket is design specifically for kids with length of 21 inches. It has an isometric design head based on Yonex's Isometric head shape technology to provide 32% larger sweet-spot (hitting area) than conventional badminton racket to help the young players hit the shuttlecock.

In year 1992, YONEX developed the world's first epoch-making technology in badminton ...the "ISOMETRIC Square Head Shape". This YONEX development continues to sets the pace of winning play. The Isometric Square Head Shape badminton racquet design provides a 32 percent larger effective hitting area than a conventional badminton racquet. Also, unlike a conventional badminton racquet with main and cross strings of varying length, the Isometric Square Head Shape equalizes the length of main cross strings in the stringbed-enlarging the sweetspot all-around for more consistent shot accuracy even on off-centre hits.
