Packed with the latest advanced technology that features in the adult Team version, the new Yonex VCORE Si 25 junior racket incorporates Bt HYBRID, a new grommet hole design that produces extra bite to generate the greatest spin.

The VCORE Si 25 also features ISOMETRIC technology, which is ultimately a head shape designed to increase the number of main and cross strings that intersect, increasing the sweet spot by 7%. This means that a compact, ISOMETRIC racquet head of 100sq. inch can generate a sweet spot equal to a larger, round-headed racquet of 107sq. inch with greater control without a loss of power.

All VCORE rackets feature the 3D Vector Shaft, which consists of deeper grooves to reduce stiffness and twisting of the frame for 20% greater stability.

Head Size: 98
Weight: 240g
Beam: 23/23/21mm
Length: 27 inch
String Pattern: 16/20

The Yonex VCORE Si series comes in an eco-friendly sack rather than a PVC cover.

Measuring Your Grip Size

Choosing the right grip size is a vital part of playing tennis. The right grip size will make your racket feel natural and comfortable.

Use a ruler and measure (in inches) from the crease fold in your hand, to the top of your ring finger. Please see table below:

Grip Size
USA (inches)
4 1/8
4 2/8
4 3/8
4 4/8
4 5/8

Note: It is always better to go for a smaller grip size, as you can easily increase your grip size with over grips.
