One of the key features of GALE SPEED wheels is their lightweight rims. The rim, which is the outer section where the tire is mounted, plays a critical role in a motorcycle's dynamic performance.

Wheels generate what's known as the "gyroscopic effect" — a resistance that tries to return a spinning object to its original axis when tilted. The farther out and heavier the rim, the stronger this resistance becomes, affecting all aspects of handling including lean, acceleration/deceleration, and direction changes.
In short, the thinner and lighter the rim, the less resistance it creates, resulting in a more responsive reaction to the rider’s input.

GALE SPEED's forged aluminum wheels are optimized for both weight and balance, allowing riders to fully enjoy the sporty performance of their motorcycles — from urban streets to winding roads and race tracks.

GALE SPEED wheels begin with high-strength blanks formed using an 8000-ton press in a hot forging process. This method applies intense pressure during shaping to refine and homogenize the metal's crystalline structure, significantly improving its strength and resistance.

A notable outcome of this process is the formation of a fibrous metal structure known as "metal flow." Forging aligns the crystalline structure along the contours of the blank, creating a material that is extremely strong and resistant to cracking in the direction of the metal flow.

In contrast, cast wheels, made by pouring molten metal into molds, do not develop this fibrous structure. Their grain structure is coarse and random, lacking the flow and strength seen in forged metal. This makes them more vulnerable to impact and repeated load, requiring thicker material by design.

Forged wheels, with fine grain and defined metal flow, offer higher strength than cast ones and can therefore be designed to be lighter. Since wheels endure constant loads and occasional high impacts, this fibrous structure results in a more robust overall design.

GALE SPEED’s forged wheels enhance the mechanical properties of the material and pursue greater strength. As a result, they’re trusted not only on public roads but also in the high-stress conditions of circuit riding.

GALE SPEED wheels are more than just lightweight parts — they are precision-engineered products born from years of accumulated design and analysis expertise.

Using CAD, we construct 3D designs of the entire wheel structure. CAE (Computer Aided Engineering) is then applied to simulate various forces from different angles. Through careful stress and displacement analysis, we optimize the structure for real-world riding conditions.
By repeating this rigorous process, we fine-tune the characteristics and performance of each wheel type.

Moreover, we combine theoretical simulations with real-world testing and feedback, including evaluations by professional riders on circuits. This iterative process of prototyping, testing, and improvement ensures high levels of completion.

While the design may appear beautiful, the core philosophy is performance that directly enhances riding. GALE SPEED wheels embody the fusion of design intent and sound engineering principles — wheels you can trust.

GALE SPEED wheels are designed not only for performance but also to offer peace of mind for long-term use. To achieve this, strict quality control and compliance with safety standards are enforced throughout the manufacturing process.

Our wheels conform to Japan’s JWL standard — a technical standard for light-alloy wheels set by the Ministry of Land, Infrastructure, Transport and Tourism. Only wheels that pass durability and strength requirements are certified.

GALE SPEED wheels are meticulously assembled by skilled technicians at our own factory, APB (ACTIVE Production Base). Our insistence on in-house production reflects our uncompromising stance on quality.

Every wheel undergoes 100% inspection — from rim runout and surface finish to paint and assembly precision. Not even the smallest defect is overlooked; only products that meet our strict criteria are shipped.

Through this unwavering quality control, GALE SPEED wheels have earned the trust of riders as products that can be used with confidence for years. Behind their beautiful appearance lies a commitment to safety, even in the parts you can’t see.
