Velnora Titanium Industry Co., Ltd. produces race-proven titanium hardware engineered to replace heavy steel OEM bolts on sportbikes, adventure tourers, motocross, and electric dirt bikes. Operating in Baoji, China's Titanium Valley, since 2013, our machine shop utilizes multi-axis CNC Swiss-turning, precision thread rolling, and in-house PVD coating to deliver fasteners that eliminate unsprung rotating mass while resisting road chemicals, brake fluids, and severe track vibration.
Precision turned and milled components ready for wholesale ordering and custom OEM brand packaging. All parts undergo rigorous dimensional and thread gauge verification.

Unlike cut threads that interrupt grain flow, our motorcycle fasteners feature continuous rolled grain fibers. This structural integrity increases fatigue endurance by over 30% under intense race vibration.
To eliminate thread friction during installation, our titanium bolts undergo controlled micro-surface polishing and optional Titanium Nitride (PVD) treatment, preserving threads through repeated paddock maintenance.
We machine customized bolt heads, specialized flange diameters, broached Torx sockets, and hollow-core drilled bolts directly from customer 3D models (STEP/IGES) with tolerances held to ±0.01 mm.
Every batch of motorcycle titanium components manufactured by Velnora Titanium Industry Co., Ltd. is verified through certified chemical spectrometry, thread go/no-go gauges, and optical inspection.
Key engineering questions answered by our Baoji technical machining team.
Grade 2 commercially pure titanium has a yield strength of approximately 345 MPa, which is insufficient for critical motorcycle loads. Grade 5 titanium (Ti-6Al-4V / TC4) is an alloyed material that delivers yield strengths exceeding 880-950 MPa, making it strong enough to handle extreme torsional, shear, and shock loads across calipers, sprockets, and suspension links.
We advise lubricating titanium threads with a copper- or molybdenum-based anti-seize paste prior to torqueing. Because lubricants reduce friction, torque values should typically be set to approximately 85% to 90% of the OEM dry steel specification to achieve proper bolt pre-load without stretching the threads.
Titanium anodization is an electrochemical reaction that creates a stable oxide layer reflecting vibrant colors (gold, blue, purple, burnt rainbow) via light interference without any organic dyes. For areas subject to high tool contact or stone bombardment, we also offer Physical Vapor Deposition (PVD) coatings for exceptional surface hardness.
Yes. OEM and ODM partnerships are our core focus. Overseas clients regularly provide 2D/3D technical drawings (PDF, DXF, STEP) or send physical OEM samples to our Baoji plant. We analyze the geometry, select certified raw titanium rod, machine the parts on Swiss CNC lathes, and share video logs of the production process.
For standard catalog sizes (M5 to M12 flange bolts, sprocket nuts), MOQs typically start at 100 to 200 pieces. For custom CNC machined parts from drawings, MOQs range from 50 to 200 sets depending on complexity. Typical production lead time is 12 to 20 business days with rapid worldwide air express delivery.
