The Karakal Flash 21: A 21 Inch Junior Tennis Racket for Red Zone Starters
Overview
The Karakal Flash 21 is a 21 inch junior tennis racket for growing Red Zone players. It suits children aged around four to six. The 7050 Alumag Alloy frame weighs 170g, with a 92 sq in head that keeps the sweet spot forgiving.
This racket ships factory strung and ready to play. A parallel frame and midsize head build a stable platform for longer rallies. Karakal fits the Flash 21 with a smiley vibration dampener to soften vibration at impact. The satin finish and colour co-ordinated grip keep the look fun for young players. Tennis in the UK peaks through the summer term, but Red Zone coaching runs across the year.

Design and Materials
Karakal builds the Flash 21 from 7050 Alumag Alloy, the same upgraded material used across the Flash range. This keeps the frame light for a growing player's arm. It still resists dents through regular coaching sessions. The parallel frame design keeps beam width even along the hoop. This spreads stress evenly and helps the racket hold up over a full season.
The 21 inch length and 170g strung weight suit players moving up from a first racket. This usually covers children aged around four to six. The 92 sq in head forgives off-centre hits while a young player builds timing. A colour co-ordinated grip and satin finish complete a frame built to last.
Key Technologies
7050 Alumag Alloy Frame: The same upgraded alloy used across the Flash range, light for junior arms but tough enough for daily coaching.
Parallel Frame Construction: An even beam width around the hoop that spreads impact and adds durability.
Smiley Vibration Dampener: Karakal's signature dampener sits in the strings to cut harsh vibration on off-centre hits.
16 x 17 String Pattern: A slightly tighter pattern than the Flash 19, adding a touch more control as players progress.

VKS Review
The Karakal Flash 21 is a 21 inch junior tennis racket built for children moving on from their first racket. At 170g it stays light enough to swing freely while adding a touch more heft than the Flash 19. The 92 sq in head keeps the sweet spot forgiving, which helps as rallies get longer. This makes it a solid choice for a child settling into regular Red Zone sessions.
As a tennis racket for young beginners, the Flash 21 suits players around four to six years old. If your child is younger, the shorter Flash 19 may suit them better until they grow into this size. For best performance, have this racket restrung by a specialist once the factory strings wear out. VKS offers a same-day restringing service from our London store. You can also visit our store in Ealing to compare the Flash 19 and Flash 21 in person.
Q&A Section
What size tennis racket does a child need after the Flash 19?
Most children move up to a 21 inch racket like the Flash 21 around age four to six. The longer length matches their increasing height and reach. Once they progress further, the LTA Orange Ball stage usually calls for a 23 inch racket.
Is the Karakal Flash 21 factory strung?
Yes, the Flash 21 comes factory strung in a 16 x 17 pattern. This lets your child start playing straight away with no setup needed. A specialist restring later on can sharpen feel once your child's technique develops.
Can a five year old use the Flash 21 safely?
Yes, the Flash 21 is sized for children around four to six years old. At 170g it stays light enough to swing without strain. Always supervise young children during play, as with any sports equipment.
Does head size matter for a junior tennis racket?
Yes, a bigger head gives a wider sweet spot for less precise contact. The Flash 21's 92 sq in head suits a child still learning timing. A too-large head on an adult frame would add unwanted weight, but Karakal keeps this model light at 170g.
Which junior tennis racket suits a Red Zone player moving up in size?
A 21 inch junior tennis racket like the Karakal Flash 21 suits a growing Red Zone player. It works well once a child has outgrown the shorter Flash 19. Choose the Flash 23 once your child moves into the Orange Ball stage.
What comes included with the Flash 21?
Each racket ships with a Karakal smiley vibration dampener fitted in the strings. It also includes a 3/4 length head cover to protect the frame. Grips are colour co-ordinated with the satin frame finish for a fun look.
