Head Tube Fork Stops

Post by VTMTcowboy » 12:14 pm Oct 15 2020

I know the obviously answer, find a welder. But, is there anything I can do in the interim to stop my upper triple clamps from hitting the gas tank? I was considering some neoprene or padded tape, but just wondering what other solutions people have come up with? I've developed a small notch on each side and would like to stop this from getting any deeper until I can get the proper welding done. Also, does anyone have pictures of a the weld job, which will help me better explain what needs to get done?

Thank you!

Some people have added shims or drilled and tapped for a small screw in the stop.

You can use Google to search this site. Type "steering stop site:kdxrider.net" without the quotes.

Someone actually makes a commercial product for the KX250 to run KX450F forks. I don't know if it will fit a KDX, but you can see what it looks like at least.

Anything to make it wider.

I saw that drill and tap one before too, that looked like a good one.

The unit from Trick is pretty slick. Easier solution is the screw mod where you drill and tap the tangs on the lower triple clamp and add a screw. Can easily be done without disassembling anything.

I did that. Tapped the existing stop and threaded in a screw. Worked well when I put KX forks on my ‘99 KDX frame.

I think that is the one. That is for clamps that came on aluminum framed bikes, but it gives a concept for forks from steel framed bikes.

I just used a piece of aluminum stock cut to the size I needed and drilled straight through the stop. Secured with a bolt and nut. Not a very pretty solution but it works fine.

I'm pretty late on this, but I did the drill/screw like others for my KX fork swap and it worked well. It was just barely hitting the left side of my tank, so I only had to do one side. Super easy to do and effective.

My solution when I put 01 YZ426F forks on my 95 KDX was to use a 98 KX250 lower triple clamp. Stops work perfectly.

Don't limit your turning ability. I heated my tank with a heat gun and used a large kitchen spoon while turning the forks to reshape the tank where the forks hit.

For the record, I did the drill, tap and install flathead allens before I reshaped my tank. Increasing the turning radius of a bike known for it's agility is not the answer. Reshape your tank, it's easy to do and keep the agility the KDX is known for.
