About this part

Grade 5 6AL-4V titanium bolt kit for the stem, in place of the steel bolt kit the bike leaves the factory with. It is about 40% lighter than the OEM equivalent and PVD-coated against corrosion. Choose from 8 finishes: Purple, Gold, Rainbow, Black, Raw Titanium (Silver), Blue, Burnt Blue and Green.

This one is cut for Altis Sigma, which we do not sell as a complete bike, so there is no fitment badge on it. Check the title against your own setup before ordering. Titanium is a weight and corrosion upgrade, not a reason to pull a fastener tighter: torque to the figure for the bolt you are replacing. Ships from Titanium Surron, and returns run through MotorHabit either way.

Questions riders actually ask

Every answer below is written by our fitment team, not a bot. Ask a new one and it gets answered within 24 hours.

Will this fit my bike?

It is made for Altis Sigma. We carry it because it fits parts riders here already run, but we do not list a verified fitment for it, so check the title and the photos against your own bike first. Ask us if you are unsure.

Is titanium actually better than the stock hardware?

Titanium is worth it for two things: weight and corrosion. This is Grade 5 6AL-4V, the aerospace alloy, not commercially pure titanium. It saves about 40% over the steel it replaces. What it is not is a strength upgrade at every size — a titanium bolt has a different yield than the steel one it replaces, so use the original torque spec.

What colors does it come in?

It comes in Purple, Gold, Rainbow, Black, Raw Titanium (Silver), Blue, Burnt Blue and Green. The finish is PVD or anodized into the surface, not paint, so it does not chip off the way a coating does.
