The Yonex Junior 25 is the brand's 25-inch kids' racquet, recommended for children aged 9 to 10, about 1.27 m to 1.40 m tall. It weighs 230 g and has a 100 in² head with an Isometric shape, which enlarges the sweet spot, and a 16x18 pattern. It is made of aluminum, which makes it durable for use in lessons, and comes pre-strung. The size and weight are designed for the stage when the child already plays on a bigger court, with a transition ball, but doesn't yet have the strength for a graphite racquet.

The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.
