Fork drop on a Triarm?

Post by veefer400 » Sat Jan 29, 2011 6:17 pm

Hi all, am close to fitting new 17" sixspokes on my Triarm... :grin:

This will of course slacken the headangle - I am aware of the CBR6 GF conversion and also aware there is no way this will be affordable until a few months...

Am I safe to remove the spring clips under the top yolk and drop the forks thro by like 10-12mm to level the bike up again? :geek:

This is something I am interested in doing too, although I already have GF's shock kit so I probably wouldn't be able to go far. I would want to know a minimum safe trail value to work from. Maybe a steering damper would be a good idea too.

Has anyone got a pair of forks handy minus springs they can compress to tell us the total travel? :pray:

You won't need a damper, if anything this mod would make the bike more stable.

Veefer just use the old trick of tying a tie wrap round your forks. After a few miles, it will slide up and show how much travel is being used. Try braking hard on a bumpy surface, where safe to do so!

Raising the forks through the yokes will reduce the rake and therefore the trail which will improve the handling but also reduces stability, hence why it is dangerous if you go to far. It's a compromise between the two.

Popped the top off a spare set of forks I had in the garage - measured the full compression & a few measurements on the forks on my bike told me there is only a 9mm gap between the seals & yokes when bottomed...

Best start saving, lol :roll: :grin:

It's well worth getting, probably the best mod you can do to a tri-arm.
