Get CatalogHigh-performance superbikes—such as the Kawasaki Ninja ZX-10RR, Ninja H2 Carbon, ZX-6R 636, and the off-road KX450F—operate under severe thermodynamic and vibrational stresses. As an ISO 9001 certified manufacturer established in 2006 within Baoji (China's "Titanium Valley"), Jovzi Titanium Industry produces fasteners engineered specifically to resolve the weaknesses of OEM zinc-plated carbon steel and standard aftermarket stainless steel.
Steel bolts introduce substantial unsprung mass, reducing suspension response times and steering flickability. Conversely, stainless steel fasteners (such as A2-70 or A4-80) suffer from low shear capabilities and severe susceptibility to galling when torqued into aluminum engine casings or swingarms. Our factory utilizes genuine Grade 5 Ti-6Al-4V (UNS R56400) and specialized Grade 23 Ti-6Al-4V ELI. With a specific density of 4.43 g/cm³ compared to steel's 7.85 g/cm³, Jovzi titanium bolts eliminate up to 45% of hardware mass while delivering a minimum tensile strength of 895–950 MPa, outperforming Class 8.8 steel and matching Class 10.9 structural bolts.
Fastener selection on a Kawasaki motorcycle is governed by structural loading modes: dynamic shear, cyclical tensile fatigue, and thermal expansion. Our direct-replacement CNC-machined titanium hardware serves dedicated critical locations:
1. Unsprung Mass Optimization (Wheels & Braking Systems): Replacing stock steel rotor bolts on Kawasaki dual-front 330mm Brembo disc configurations with our forged-head M8×30 DIN 6921 Grade 5 Flanged Bolts cuts rotating unsprung weight directly at the wheel hub. This reduces the gyroscopic precession force, resulting in faster directional changes at race speeds. For front radial brake calipers, our M10×1.25×60mm rolled-thread socket bolts prevent caliper deflection under heavy braking, preserving consistent lever feel.
2. High-Temperature Exhaust & Cylinder Head Fastening: The supercharged Kawasaki Ninja H2 generates excessive exhaust gas temperatures that rapidly oxidize and seize factory steel studs. Jovzi supplies CNC-turned M8 Titanium Exhaust Manifold Studs & 12-Point Aero Flange Nuts. Grade 5 titanium maintains structural integrity under cycling thermal loads without galling or scaling, enabling stress-free maintenance and header swapping.
3. Engine Casing & Fairing Kits (Corrosion-Free Aesthetic Integrity): For track builders and custom ateliers working on Z900, Z650, or retro Z900RS platforms, our full-bike casing kits replace case bolts with M6 DIN 912 or Torx taper-head fasteners. Jovzi applies industrial PVD (Physical Vapor Deposition) and multi-stage anodization to achieve rich, heat-stable colors: Electric Kawasaki Racing Green, Anodized Burnt Blue, Titanium Gold, and PVD Diamond-Like Carbon (DLC) Deep Black.

Across European, North American, and Australian motorsport hubs, the motorcycle aftermarket has shifted permanently away from cosmetic aluminum dress-up screws toward track-homologated Grade 5 titanium. Aluminum fasteners (such as 7075-T6), while lightweight, possess insufficient shear strength for structural applications and are strictly prohibited on safety-critical components like fork clamps, footpeg brackets, and brake linkages.
Simultaneously, professional track teams participating in MotoAmerica, BSB (British Superbikes), and FIM WorldSBK demand documented quality assurance. Every shipment from Jovzi Titanium includes complete EN 10204 3.1 Mill Test Certificates (MTC) directly verifying heat number, spectral chemical analysis, elongation, and yield limits. Our close cooperation with the authorized BaoTi Testing Center guarantees that Jovzi hardware fulfills international ASTM F136, ASTM B348, and DIN/ISO standards, giving racing distributors confidence in every batch.
Direct manufacturer capabilities situated at the global epicenter of titanium milling and precision engineering.
Rather than cut machining which severs grain lines, our bolt threads are cold-rolled after heat treatment, delivering superior continuous grain flow and up to 300% greater fatigue lifespan under violent track vibration.
Equipped with high-precision multi-axis Swiss CNC lathes and machining centers, maintaining tolerances within ±0.01mm. We produce dimpled race heads, race-spec pre-drilled safety wire holes, and customized flanged socket profiles.
Every single titanium fastener batch originates from traceable melting heats. We provide EN 10204 3.1 inspection certificates verifying raw chemistry, tensile yield, and elongation verified by BaoTi Laboratory.
Over 6 years of OEM private-label manufacturing. We support customer laser logo marking, customized pitch threads (e.g., M10×1.0 vs M10×1.25), and tailored fastener kits organized per motorcycle assembly station.
Offering precision PVD rainbow, electric green anodization, burnt blue flame-treated effects, and high-wear DLC (Diamond-Like Carbon) coatings that prevent galvanic galling and deliver outstanding showroom presentation.
Stock standards (DIN 912, DIN 6921, ISO 7380) ship within 48 hours. Flexible MOQ requirements from single sample race sets to container-scale distribution lots, backed by worldwide express DDP delivery terms.
Technical answers to the most common queries raised by race teams, distributors, and aftermarket workshops.
Yes, absolutely—provided they are manufactured from hot-forged and thread-rolled Grade 5 (Ti-6Al-4V). Grade 5 provides high shear capacity (over 550 MPa) and tensile properties matching 10.9-grade high-tensile steel. Never use pure Grade 2 titanium or aluminum for disc or caliper applications.
Because titanium has a distinct coefficient of friction compared to steel, we recommend applying anti-seize paste (copper or nickel-based) or medium-strength thread locker. Fasteners should generally be torqued to OEM Kawasaki manual values or reduced by approximately 10–15% if lubricated.
Under dry conditions, titanium is inert due to its protective titanium dioxide film. In humid, salty, or track-wash conditions, using an anti-seize paste or molybdenum disulfide compound prevents galvanic potential differentials between aluminum and titanium, ensuring anti-galling performance.
Yes. Simply provide the Kawasaki OEM part number (e.g., 92153-series or 92154-series), a physical sample, or a technical drawing (PDF/DWG/STEP). We reverse-engineer the thread pitch, shank length, and head clearance to guarantee 100% plug-and-play fitment.
For standard in-stock inventory items (M6, M8, M10 DIN 912 and DIN 6921 hex flange bolts), the MOQ starts at 100 pieces per size with dispatch in 48 hours. Custom CNC bolts or specific race color anodizing runs typically require 200–500 pieces with lead times around 15–20 working days.
Yes. Every dispatch is accompanied by an EN 10204 3.1 inspection certificate stating exact chemical heat lot values and mechanical test results (tensile, yield, elongation). Independent third-party inspection reports by the authorized BaoTi Test Center are readily provided upon request.
