  • tree and fork help

    I am building a third one of these beautiful old bikes. I am going to do a lot of custom work on it though. My quetion is "Are there any tree and fork set ups fromother bikes and years that are a direct mate up?" I would like to use newer forks on this build up.

    Try a search, someone is running busa forks, supposed to be a direct swap if you get a new bearing(s) if I remember correctly. Guys in Europe are using some sort of forks that are supposed to be easy to swap too, but I can't remember the bike their off of, seems like it wasn't available over here. Others are using FJ1100 forks, which are supposed to swap, but aren't bolt on, some mods and/or spacers need to be machined. I'm planning to do FJ forks....theres a thread.

        Here's the FJ swap posts....

        Most of the sport bike forks are designed for a 'longer' steering neck, and axle/wheel/brake differences means none of these are a 'bolt-on' deal. You will be fabricating some parts, if only for mounting a headlight. Watch out for bar size too (7/8" vs 1"), as this will affect your hand controls.

          I knew a little fab would be needed, I just wanted the neck and triple to line up and sit the bike correct. Appreciate the advice though.

            That is the trick. Nearly all the fork swaps you see involve forks off sport bikes, and they'll almost always lower the front of the bike. I went through considerable work to maintain stock height on mine with the FJ forks, and stayed within about 1/4 inch of stock. Lowering the front will decrease trail (all else being equal) making for a 'quicker' steering bike but increasing the chances of having a 'tank slapper'. But most sport bike trees have less offset (which increases trail) so you need to check.
