Description

You have put your time and money into a great bike, so it makes total sense to choose top-tier hardware that easily outlasts the frame itself. We are the very first shop to source this premium titanium upgrade kit, made locally by our trusted metal specialist. While these parts look stunning on naked frames, the real value comes from long-term durability. Titanium metal is significantly lighter than standard steel, inherently tougher, and completely immune to the ugly brown rust that destroys standard factory bolts. This is the ultimate one-time purchase for riders who want to prevent rounded heads and avoid snapped engine bolts during future garage work on local roads.

💡 RECOMMENDED HARDWARE PAIRING: Complete your total rust-free engine bay look by replacing the rest of your weathered factory screws next. Match these premium cam parts along with our Stainless Steel Engine Bolt Kits to banish rust forever. Browse Titanium & Stainless Hardware here.

🔧 Install Tips

  • Follow Factory Tightness Specs: Titanium metal has unique friction properties when turning. Always use a proper hand torque wrench and lock them down to the exact original settings noted in your repair manual. Never overtighten these into your engine block!
  • Use Anti-Seize Paste: Dab an incredibly fine smear of copper grease or anti-seize thread lubricant paste directly onto the bolts before insertion. This stops threads from cold-welding together under intense engine heat.
  • Check Placement Locations: Take a look at the product images above to confirm the exact layout spots on your engine cover casing before you unbolt your old factory screws.
📧 NOT SURE IF YOUR VALVE COVER IS LEAKING OIL FROM AN OLD RUBBER GASKET? If your spark plug holes are filling with oil or you want to double-check before unboxing your kit, you can upload a crisp photo of your upper engine block on the forum to get immediate advice from other owners.
