Turn Your Concepts into Market-Ready Products

We collaborate with premier motorcycle brands, high-end distributors, and bespoke custom shops globally. From initial CAD sketches to FEA stress verification and multi-axis CNC milling, we engineer wheels that define the industry.

Learn More

Tailored Fitment & Offsets

Guaranteed Zero-Friction Fitment. Millimeter-level precision for ET, PCD, and center bore (17"–24")—engineered for flawless brake caliper and swingarm clearance with no modifications needed.

Premium Custom Finishes

50+ Show-Quality Finishes. From hand-brushed and mirror polishing to transparent candy coats and two-tone finishes—salt-spray tested for superior weather and corrosion resistance.

OEM Logo & Laser Engraving

Full Private-Label Customization. High-precision laser engraving, bespoke center caps, and tailored retail packaging designed to elevate your brand value with strict IP protection.

Rapid 3D CAD & FEA Approval

Fast-Track R&D & 1-Set MOQ. Full 3D CAD modeling and FEA stress simulation delivered in 48 hours. Flexible production starting from a single prototype to eliminate your inventory risk.

Precision Service Process

From initial CAD design concepts to destructive safety benchmarks and international freight delivery.

01

Inquiry & Design Alignment

Verify fitment geometry, wheel diameter, rim width (J-value), PCD, ET offset, and center bore. Choose from existing open tooling or supply sketches/samples for bespoke 2D CAD engineering and photorealistic 3D rendering sign-off.

02

FEA Simulation & Tooling

Pre-production structural validation using Finite Element Analysis (FEA) to simulate radial load bearing, cyclic fatigue, and weight optimization. Custom casting/flow-forming mold fabrication or forged billet parameter configuration.

03

Precision Manufacturing

10,000-ton forging, low-pressure casting, or flow-forming flow-stretch production. Multi-axis CNC milling for spoke contours, lug seats, and center bores, followed by hand polishing, electrostatic powder coating, or PVD finishes.

04

Rigorous Testing & QC

Three critical destructive safety evaluations: dynamic radial fatigue, rotary bending fatigue, and 13°/30° impact resistance testing. Full CMM coordinate measuring, dynamic runout balancing, helium leak detection, and salt spray exposure.

05

Safe Packing & Logistics

Zero-scratch export grade protection: EPE foam edge rings, non-woven dust bonnets, hard cardboard rim caps, and heavy-duty corrugated cartons on wooden crates. Global FCL/LCL ocean freight and air express with end-to-end tracking.

Comprehensive Quality & Warranty Terms

We specialize in transforming concepts into aerospace-grade reality, backed by our comprehensive warranty and guaranteed fitment pledge.

Warranty Verification
01

Structural Warranty

We provide a warranty covering manufacturing defects and material flaws in the wheel itself (such as cracking, spoke fracture, or loss of roundness). Forged products come with a lifetime warranty, while cast and flow-formed products are covered by a 3–5 year quality guarantee.

02

Finish / Coating Warranty

Peeling, flaking, blistering, or severe discoloration of the wheel surface finish (including paint, electroplating, brushed finish, or clear coat)—whether due to material issues or the manufacturing process—is typically covered by a warranty period of 1 to 2 years.

03

Exclusions

Exclusions: Damage from impacts with potholes, collision damage, use in track racing, improper modifications, corrosion caused by chemical cleaning agents, or damage resulting from improper car washing or maintenance.

04

Fitment Guarantee & Claim

If you purchase based on our official recommendations, we guarantee 100% compatibility regarding bolt pattern, offset (ET value), and clearance for brakes and suspension components. We also offer a streamlined claims process: simply provide your order number along with clear photos of the damage, and a dedicated representative will assist you immediately.
