I'll do another search, I have bought 10 or so KTM triples and have never needed one so I can't imagine where they are all hiding. I'll reach out to you if I can't find one and need to buy thanks!

I've been waiting on parts and some specialized tooling to get the next part done, mounting the swingarm. I machined down the original axle from 20mm to 17mm so it could now function as the swingarm pivot bolt. Next I needed to make up some bosses to fit into the frame that would now locate the axle in the original 20mm frame holes.

I made up one side and it fits great. It's a little long on purpose, I installed in in the frame (it's dead blow press fit) and ran the axle through. I then used a telescoping gauge to measure the opposite distance.

A little math to get them to the correct length and voila. I turned a chamfer around the inside of the spacer so that I have a groove to weld in to the frame. They aren't finished because I decided to buy an actual 17mm drill bit. I drilled it with a 21/32" which is 16.67mm. Then I realized that I don't have a drill chuck big enough to hold a 17mm shank so I'm waiting on a buddy to get one on loaner for me.

You can also see in this pic how far off the chain is from the KTM to the ninja. I successfully machined down the stock CS sprocket on my CBR to get it closer to the block. I then spaced out the rear sprocket using a plate of aluminum I drilled for the bolt holes. I will have to do the same thing here and also move the guard outboard.

I've been buying steel rods in any diameter I can get my hands on, these I found in 3' lengths 1.5" dia at a scrap yard for $1.50/lb. Great to have on hand for things like this. I also try and keep a bunch of aluminum rods for the same thing.

Then I need to make up a tube to fit between the arms of the swinger to keep the bearings in place. Once the swingarm is located I can cut the subframe to make room for the shock. I think redoing the subframe tubing will be easy with some new DOM tubing and my bender. Should actually look identical to the clutch side.

The top shock mount I have lots of ideas for. I really want to get the suspension angles correct so I will probably spend quite a bit of time measuring and checking and checking again. First I need to finish up the front end and getting the forks on so I can get the rake correct.

I got my new roller bearings for the steering tube and will finish up the lathe work to get the stem mounted.
We're not out here to rough it. We're here to smooth it. Things are rough enough in town.
