Executive Summary
The Yonex EZONE (7th Gen/2025) occupies the "Power" slot in the Yonex matrix, sitting opposite the VCORE (Spin) and PERCEPT (Control). Known as the "easy power" frame, it bridges the gap between stiff, pure-power racquets (like the Babolat Pure Drive) and flexible control frames.
Key Characteristic: The signature isometric head shape creates a sweet spot that feels 7% larger than traditional round heads, offering maximum forgiveness on off-center hits while maintaining a plush, muted feel.

Model Comparison Guide
Select the correct "Iso" frame based on swing speed and physical strength.
EZONE 98
The choice for modern baseliners who generate their own pace. Offers controlled aggression and precision for hitting lines.
EZONE 100
Maximum versatility. Provides "free power" on defense and stabs. Best for players needing help with depth.
EZONE 98 Tour
Significantly heavier swingweight. Designed to absorb heavy pace and crush the ball through the court.
"Plus" Models (+)
Available in 98+ and 100+. The extra 0.5 inch adds massive leverage for serves but reduces maneuverability on defense.
EZONE 100L
A lighter version of the EZONE 100, designed for club players who want the EZONE's comfortable, powerful character with a more manageable swing weight. At 285g it's easier to generate racquet-head speed, making it popular with older players and those returning from injury.
Technical "Must-Knows"

String Setup Guide
The EZONE is easy to tune with strings — dial in more control, comfort, or spin without changing frames. Reference range (EZONE 98): 45–60 lbs (20–27 kg).
Quick Start (Most Players)
- Start point (full poly, 1.25): 50–52 lbs (22.5–23.5 kg) for a balanced blend of control + depth.
- If the ball flies long: go +2 lbs next restring, or choose a firmer/thicker poly (e.g., 1.30).
- If your arm feels beat up: drop 2–4 lbs, choose a softer poly, or switch to a hybrid (poly mains + multi crosses).
- EZONE 100 note: it generally launches easier; consider +1–2 lbs vs your 98 tension for similar control.
Recommended Setups by Goal
| Goal | Recommended Setup | Tension | What You'll Feel |
|---|---|---|---|
| Balanced | Soft poly (full bed), 1.25 gauge | 50–52 lbs | Clean response, good depth, predictable launch |
| More control | Firmer poly or thicker gauge (1.30), full bed | 52–55 lbs | Lower launch, more confidence accelerating |
| More comfort | Hybrid: poly mains + multi crosses | 48–52 lbs (mains) | Softer impact, better pocketing, easier on the arm |
| More spin | Shaped poly in mains (or shaped full bed) | 48–52 lbs | More bite + height over the net, slightly livelier launch |
| Max durability | Thicker poly (1.30) or durable hybrid | 50–54 lbs | Stability over time, less string movement |
Top 3 Recommended Strings
Best for: Players wanting comfort + control without sacrificing feel.
Engineered by Yonex to complement their frames. Offers a soft, muted response that pairs perfectly with the EZONE's vibration dampening. Maintains tension well and doesn't feel harsh on off-center hits.
Best for: Modern baseliners who prioritize spin generation and ball bite.
Square-shaped profile creates maximum string movement and snapback. The EZONE's power platform lets you swing aggressively with confidence. Note: tension drops noticeably after 4–6 hours of play.
Best for: Advanced players (4.5+) seeking maximum control and precision.
The gold standard for tour-level control. Crisp feel and excellent spin with minimal string movement. Pairs well with the EZONE 98's surgical precision but can feel firm — consider dropping tension 2–3 lbs from your usual setup.
