Default YZ KYB Conversion

Anyone got any ideas on how to set up steering stops for the YZ triples in a GasGas EC250 frame?

I suppose the other option is to try to find a set of 48mm GasGas triples to fit these forks into but there is nothing on ebay.

should be on the forum in one of the kyb threads, but the ones i remember was welding a tab on the steering head (like the yz have) and the other was door-stop rubbers screwed into the bike frame where the tubes come in contact, and the last being what you mentioned and what i had

I screwed then welded blocks onto the YZ triple lower, was pretty easy and clean and fit for purpose. Search my pictures should find it.

Bolted everything together just to see how it all mates together and it seems the lower triple clamps will hit the rads first. With the triple touching the rad, there is a fair bit of distance to reach the frame and not really anything to bump off.

At this point, I'm thinking a tab welded on to the front of the steering head would be the best solution.

I was thinking this through as well. I have a home machine shop so shouldn't be overly difficult thing to accomplish. The only issue is the distance from the triple to the frame when the triple is touching the radiators. I need to spend some more time measuring things up.

Modifying the triple would be preferable as I have a spare set of YZ triples and it is easier to take a triple clamp to the welder vs the whole frame.

Ahh, here we go, post 43. There is weld a bit underneath but they butt up against the edge so they cant go anywhere. Several years on.

Thanks, I appreciate it.

I have tagged all these threads so they will appear together in the timeline ..... at least for a while. Its almost like the forum should have a dedicated section for KYB forks and fork swaps.

It is good to have my own home machine shop for this kind of project. The only thing I don't do is weld but I have a really good welder on speed-dial.

It is interesting to see the welded triple clamp blocks. Basically exactly what I was contemplating. I have even considered drilling tapping the block so an adjusting screw can be installed.

Yeah I wanted as much flat area to hit at the same time to spread the load.

I fabbed up a plastic block and can see how it all works. There won't be a need for an adjustable screw. Your pics really helped.

As taking a triple clamp to the welder is significantly easier than hauling the entire bike down to his shop, I will be doing this steering stop mod rather than adding a block to the steering head. I also have a spare YZ triple clamp, which means that screwing the whole thing up comes with less risk/cost.

Thinking back I think my first template was in nylon to get the size right.
