Kit Information

This kit includes titanium bolts for your bike’s engine, including the oil filler and drain plugs. Engine mount bolts are not included.

Each DocWob fastener is CNC machined from premium Grade 5 Ti-6AL-4V aircraft-grade titanium, heat-treated before machining for added strength. Titanium weighs 48% less than standard steel and is naturally resistant to rust and corrosion.

Threads are rolled, not cut, for maximum durability, giving your bike that factory-level finish and performance.

Kits are supplied in clearly labelled bags for each specific fitment, making installation easy. They also come in a dedicated parts box, so you can store the original bolts if you prefer to re-fit them later.

We recommend using a high-quality silicone-based grease during assembly and torquing bolts to OEM specifications.

Important note:  Titanium nuts are not supplied for titanium bolts, as they can seize (gall) when used together.

These are the exact bolts used by factory teams, often redesigned for improved strength and easier fitting.
