Custom Tree Offset Recs.
« on: July 15, 2018, 02:52:40 pm »
Hello All.

I'm looking to make my own triple trees / stem for primarily weight and aesthetic reasons.

And while I'm at it - curious if there's any recommendable offset changes I should make.

To note - bike has 18 inch front and rear, stock conventional forks with racetech gold valves, ikon rear suspension on a 77K swing arm.

Stock offset is probably fine - but was curious what all of you have for input. And if there's some triples I should reference for aesthetics, not planning on a simple water jet job.

Cheers,

Dunc

Check trail and shoot for about 95mm as the bike sits.

Was hoping you'd chime - referencing a lot of your build.

Is 95mm the sweet spot you've found?

It's what I'm running and what many more modern sport bikes run. It's considered a close to perfect number.

Close to perfect sounds good enough!

Bike will be a roller in the next few weeks. Will be able to take measurements then and get to CAD.
