The HEAD Radical 21 Junior is designed for young starters aged 4 to 6 years (height around 100–115 cm / 40–45 inches). Finished in the vibrant, modern red and pastel blue cosmetic of the adult Radical series, it gives young players the look of a tour racquet while providing an accessible, easy-to-swing platform for learning fundamental mechanics.

Weighing 180 grams (unstrung) with a 21-inch length and a 81 square-inch head size, it delivers the ideal balance of lightweight maneuverability, control, and sweet-spot forgiveness for Red Stage (Stage 3) low-compression tennis balls.

Performance Profile

  1. Maneuverability (10/10): Exceptional. At an ultra-light 180 g, it allows young players to swing through the air with ease, building smooth technique without physical strain on developing wrists or shoulders.
  2. Forgiveness & Sweet Spot (8.5/10): Generous. The 81 sq. in. head size enlarges the effective hitting zone to make clean contact simple for early-stage rally play.
  3. Arm Protection & Comfort (9.0/10): Excellent. Features HEAD’s DampPlus insert positioned just above the grip, which actively absorbs impact shock before it reaches the child's hand.
  4. Durability (8.0/10): Solid. Constructed with lightweight aluminum for high frame durability, making it ideal for young players prone to bumping racquets against the court surface.

Key Technologies

  1. Aluminum Construction: Lightweight, durable alloy construction engineered to withstand rough play while keeping the swing weight low.
  2. DampPlus Insert: A specialized dampening element isolated above the handle that filters out high-frequency vibrations upon ball impact.

Best Suited For

  1. Junior Starters (Ages 4–6): Children standing between 100 cm and 115 cm tall who are taking their first steps on the court.
  2. Red Ball / Stage 3 Players: Youngsters learning the game using Red low-compression starter balls on mini-courts.
  3. Radical Line Enthusiasts: Young players who want to match the bold styling of HEAD's tour-level Radical frames.
