Introduction: A Legacy of Spin

The Yonex VCORE story is one of continuous innovation. The 7th generation was a masterpiece in its own right, celebrated for its incredible spin potential and remarkably comfortable feel, thanks to technologies like 2G-Namd Flex Force and Vibration Dampening Mesh (VDM). It offered players a unique blend of precision and RPMs, making it a favorite among everyone from club players to tour professionals.

Enter the 8th generation. For 2026, Yonex hasn't just tweaked the paint job; they've gone back to the drawing board on the frame's architecture. The goal was clear: increase power and feel without sacrificing the spin-friendly DNA of the VCORE. As we noted in our initial video review, "Below the surface of these two frames lies a few changes!" Let's peel back that surface and see what's new.

Technology Deep Dive: What’s New in the 8th Gen?

On paper, the core specs of the Yonex VCORE 98 remain remarkably consistent between generations. Both frames feature a 98 sq. in. head, an unstrung weight of 305g, a 6 pts Head Light balance, and a similar flex rating hovering around 63-64 RA. However, the 8th Gen’s performance shift comes from subtle but impactful changes to the mold and material composition.

However, beneath the surface, Yonex has implemented several meaningful changes:

The beam width increase—from 23/23/21 mm to 23/23.5/22 mm—may seem modest, but it signals a shift toward additional power and stability. The midsection and throat are now slightly thicker and feature a flatter, more streamlined construction.

1. Mold and Frame Geometry

The most significant change in the 2026 model is the redesigned hoop. Yonex has extended the frame's top length and tapered the inner frame. This accomplishes two things: it creates an even larger sweet spot within the signature Isometric head shape and enhances flex for better ball pocketing.

Furthermore, the beam geometry has been streamlined. The "Aerofins" of the previous generation are gone, replaced by a more aerodynamic shape that promises faster swing speeds. As we mentioned in our video, "this new shape gives you more speed across the entire frame."

2. Stringbed Technology

Spin generation is heavily reliant on string movement. To boost this, Yonex introduced new grommets at the top of the hoop in the 8th Gen. These grommets feature a more horizontal design, allowing the strings to snap back more freely and aggressively upon impact.

3. Material Science: The Arrival of SERVO FILTER

While the 7th Gen utilized 2G-Namd Flex Force and VDM to create a spin-friendly, comfortable feel, the 8th Gen introduces a new player to the lineup: SERVO FILTER. This specialized carbon fiber layup is designed to work in tandem with the existing technologies to maximize power, stability, and ball pocketing, resulting in what Yonex describes as a more "responsive, confidence-inspiring hitting experience".

On-Court Performance: 7th Gen vs. 8th Gen

Specs and tech are just numbers until you step between the lines. Here is where the two generations truly differentiate themselves.

Groundstrokes: Power and Feel

8th Generation:
From the baseline, the 8th Gen makes its presence known immediately. Our playtesters noted a distinct increase in power and plow-through. The stringbed feels noticeably crisper and more responsive than its predecessor. As we described in our video review, "This was something I personally really enjoyed, as I found that the previous generation offered a slightly more muted feel upon impact."

This enhanced feedback inspires confidence. The more direct connection to the ball allows for aggressive swinging, with a consistent ball flight and a slightly lower launch angle than the 7th Gen. This makes flattening out shots for winners a more controllable endeavor. One playtester noted that while the power is abundant, it requires a full commitment to the swing; decelerating can lead to balls flying long.

7th Generation:
The 7th Gen is still a powerhouse of spin, but its feel is where it differs most. It offers a plusher, more muted response at impact. This provides exceptional feedback on where the ball meets the strings, but in a dampened way. The launch angle feels slightly higher, making it incredibly easy to loop the ball deep into the court with heavy topspin. While it may not have the same raw pop as the new model, its control and spin consistency are what made it a classic.

Volleys: Connection and Touch

8th Generation:
The crisper stringbed of the 8th Gen shines at the net. Punch volleys and put-aways feel decisive and stable, with a solid connection that leaves no doubt about the shot's outcome. "Volleys were very enjoyable," we noted in our video, "the crisper feeling string bed had me feeling very connected with the ball."

Where the 8th Gen pulls ahead is in its predictability on touch shots. The video review highlighted a key difference: "The biggest difference I noticed at the net... was the trampoline effect on softer touch volleys. I found that the previous generation did have a few moments where the string bed was a little inconsistent." The 8th Gen eliminates that hot launch, providing a more controlled and reliable response on delicate drop volleys and angles.

Serve: Energy Return vs. Dwell Time

8th Generation:
On serve, the 8th Gen feels like it has a higher energy return. The combination of the stiffer beam and more responsive materials translates into free pace on first serves. As we stated in our review, "With the 8th Generation feeling crisper, I found that I enjoyed really going after my first serves and received what felt like a little more energy return." Slice and kick serves also benefit from the aerodynamic frame, which whips through the contact zone with ease.

7th Generation:
The 7th Gen remains a fantastic serving racquet, but its personality is different. Power is still accessible, but the feel is softer and the ball seems to stay on the strings a fraction of a second longer. This improved dwell time can be a massive advantage for players who like to shape their serves with heavy spin and precise placement, offering a greater sense of control over the ball's trajectory.

Target Player: Which VCORE 98 is for You?

Choosing between these two generations ultimately comes down to personal preference regarding feel and your primary source of power.

Choose the Yonex VCORE 98 8th Gen (2026) if:

• You prefer a crisp, direct, and responsive feel over a muted one.

• You are an aggressive player looking for extra free power and pop on your groundstrokes and first serves.

• You want a more predictable and controlled response on touch volleys.

• You have a fast, loopy swing that can harness the frame's power and appreciate a slightly lower, more penetrating launch angle.

Choose the Yonex VCORE 98 7th Gen if:

• You love a plush, comfortable, and muted feel that provides exceptional vibration dampening.

• You rely on creating your own power and prefer the enhanced dwell time for shaping shots with heavy spin.

• You are a spin-heavy player who wants a slightly higher launch angle to help clear the net with margin.

• You are an intermediate player looking for a forgiving, spin-friendly frame with a more classic, arm-friendly response.
