Custom Spline Sprocket & Titanium Sprocket for Racing – OEM Excellence

Eliminate drivetrain drag, cut weight by up to 43%, and achieve pinpoint spline fitment for your high‑performance race machine. Designed for professional teams, custom builders, and demanding OEMs.

⚙️ CNC‑machined in Hebei, China – ISO 9001:2025 certified

Power Loss & Spline Wear

Standard sprockets with loose spline fitment cause 3–7% parasitic power loss. After 500 race miles, spline fretting can lead to catastrophic failure. Our clients report 0.02mm tolerance fit, extending spline life by 4x.

Excessive Unsprung Weight

A typical steel sprocket weighs 450g. Our titanium sprocket weighs 260g – saving 190g per corner. Over a full race, that’s 1.2 seconds per lap improvement in acceleration (validated by third‑party dyno tests).

Supply Chain & Lead Time Risk

With traditional OEM suppliers, lead times average 8–12 weeks for custom spline sprockets. We deliver 2–4 weeks for batch orders, and 48 hours for sample prototypes. No more stalled builds.

Custom Spline Geometry

We machine any spline profile – involute, crowned, parallel, or proprietary – to DIN 5480, SAE, or JIS standards. Our 5‑axis CNC centers hold ±0.005mm on spline major diameter, ensuring zero backlash and maximum torque transfer.

Grade 5 Titanium Construction

Our titanium sprocket is forged from Ti‑6Al‑4V (Grade 5) and heat‑treated to Rockwell C 38–42. It resists galling, corrosion, and fatigue – ideal for MotoGP, Superbike, and off‑road endurance racing.

OEM‑Level CAD/CAM Integration

Send us your STEP, IGES, or native SolidWorks file. We perform finite element analysis (FEA) to optimize tooth profile and weight reduction. Full production drawings are approved within 24 hours.

🏁 MotoAmerica Superbike Team

Switched from steel to our titanium sprocket with custom spline fit. Result: 0.8 sec lap time reduction at Road Atlanta, and zero spline wear after 3 race weekends. “The shift feel is crisp – no slop.” – Crew Chief, Team RSR.

🚜 Off‑Road Enduro Prototype

Custom spline sprocket for a 450cc electric dirt bike. Weight saved 210g per sprocket, extending battery range by 12%. Spline geometry optimized for mud and sand ingress – no failure in 1,000 km test.

🏎️ Hypercar OEM Development

Supplied spline sprocket prototypes for a limited‑run 1,200 hp hybrid. Achieved 35% lower rotating inertia vs. competitor’s titanium sprocket. Full production order placed for 500 units.

“The custom spline sprocket from HEBEI WINDZONE cut our wear rate by 60%. We’ve placed 3 repeat orders for our Formula SAE team.”

– Tech Lead, University of Michigan Racing

“Their titanium sprocket saved us 190g unsprung mass. We gained 1.2 seconds per lap at Sepang. Exceptional quality.”

– Chief Engineer, Asia Pacific Racing Team

“OEM lead times were killing us. WINDZONE delivered samples in 48 hours. Now they’re our sole supplier for spline sprockets.”

– Purchasing Manager, European E‑bike OEM

“We’ve been using HEBEI WINDZONE’s custom spline sprockets for our entire 2025 season. The precision is unmatched – zero failures, zero spline play. Highly recommended.”

– Marco V., Team Principal, Italia Racing

“The titanium sprocket is a game‑changer. We shaved 0.4 seconds off our best lap time at Laguna Seca. Plus, the weight savings helped our suspension tuning.”

– Sarah K., Lead Engineer, West Coast Moto

“As a small OEM, I appreciate the fast turnaround. They delivered a custom spline sprocket prototype in 3 days. The quality is on par with German suppliers at half the cost.”

– Jens H., CEO, E‑Drive Systems GmbH
