        Anything is possible. No it's not a direct fit, but if it were then every joey would have done it.

        The only reason I didn't do it, was because I spent many many nights lining up my supermoto wheels with my current setup, changing the arm, whilst trivial, would have undone all that work.

          At first Im spotted the 2 problems I need to deal with : 1st - the linkage fitment is different
          2nd - the brake bracket .
          Wondering if the yz bracket will fit my caliper and line up properly with the disc 🤔

              To do it properly you are going to need to realign the whole geometry of the bike.

              With the new swingarm you are going to need the YZ brake carrier. Which will need modifiying to either accept your brake, or use the YZ brakes.

              Either way the swingarm needs altering to fit between the frame and the engine.

              This will cause the sprocket to be out of alignment with the rear sprocket, which is going to to cause undue stress to the gearbox bearings. This will need correcting by either shimming or machining.

              You are then going to find the front and rear wheels are no longer in line. So this will need altering to ensure that the front and rear wheels are inline, and the front and rear sprockets are inline.

              If you don't then you will find the bike will have a tendency to crab or to cause excessive damage to the gearbox.

              This is why my front wheel is off centre from the forks. This was done to ensure the front and rear wheels line up perfectly, whilst maintaining the correct geometry for the front and rear sprockets.

              I'm all for the swingarm conversion, but it sounds like you haven't thought this through enough?

              If you're going to do, do it right. Is all I'm going to say.

              It's just a case of measuring once, twice three times to be sure. This is the reason why I didn't use the alloy swingarm, AFTER I had already done all of this measuring.

              I should have done it all at one time and saved myself the effort of measuring twice.

              If any of that is unclear I am happy to go into more detail.

                @Calum yeah to be honest Im thought its lot easier than it really is and I havent the yz swingarm in the hand to get the measurements.
                Definitely I have only 2 ways of doing this: properly or stock swingarm.

                  I'm keeping the stock arm and swapping the wheel hubs over just to keep the project going ATM. I did like the idea of the yz wheel adjustment on the rear as it looks smarter than the dt 1

                      Well I have seen quite a few DTRs with YZ250/WR400 swingarms. Doable.

                      Custom linkage brackets, fabricated an welded...

                      Complete YZ/WR rear end,, new chain/ possibly only a 520.

                      A earlier style YZ/WR shock will only just clear the exhaust, and will need a custom spacer just to fit it into frame shock tower!

                      This is a proper fabrication job.

                      This was the very reason a WR200 swingarm was the ONLY choice for me.

                      Keep it real

                          Yeah if you wanted to do minimal fabrication then buy a YZ rear end and shock, this would minimise a lot of stuff.

                          If I had a garage I would happily make these sorts of bits for people. But I am so tight for storage at the moment it simply is not possible!

                                  As said I got all mine off simply bearings no problem. Saved loads of money as well!

                                        Small update . Engine rebuilt and frame finally came back from powdercoating. Not sure if I love the change but have to deal with it now 😂 0_1491671835721_20170407_180013.jpg

                                        @Zrako If it's not as you originally envisaged, most of it will be hidden anyways, so it's all good really!!! 😉
