Brilliant, and thank you for your reply
I will be doing some more measuring tonight before the first swingarm swap.
Want to get the numbers before I start with the fun.
Update coming soon _________________ I'm not a complete idiot - Some parts are missing |

Finally got the RG swingarm out and got a chance to do some measuring . . . . .
The RG's alloy swing arm is very light, I can see why the can crack . . . .
A quick measure of its width at the swing arm pivot was 190mm. D'oh . . . .
The DR600 steel swingarm is 210mm width, and is substantailly heavier than the RG.
The plan from here is to take 10mm of each end of the DR600 swingarm, remachine the bearing races, and possibly make some bronze bush's with grease nipples.
I am still going to extend the swingarm 100mm, and lower the bottom shock mount 17mm.

Well whilst waiting from the swingarm to be extended 120mm I went to the Phillip Island Classic races.
I spied this Trident Engineering replica of the Heron Suzuki Superbike.
On closer inspection the rear full floater setup caught my eye.
I think I may be able to incorporate some of this into the RG's swingarm setup???

Im a happy chappy!!
Today I picked up a set of DRZ400 wheels for the RG250.
The ones I got with the DR600 donor bike were not much chop
The front rim had cracks all around and spokes missing, the rear has 2 massive flat spots. I also want to run a disc rear brake.

G'day
Just got a few Phone pics emailed through of the progress to date.
Pivot has been machined and narrowed 20mm
Bottom shock mount has been removed ready for lowering 18mm
and it has been cut ready for the 120mm extension to be welded in.
Should be done in the next week or so . . . . .

Oh well, that didn’t turn out quite as I had expected . . . . . .
I think the best way to share my current situation is by being a bit philosophical about it.
When you tell someone under NO circumstances are you to touch or modify the frame, apparently that isn’t clear enough.
I took the RG250 to a fellow who had previously modified the fuel tank on my XR460/4. We sat down and I explained what I was after, he took notes in his big book and said it would take about 4 weeks as he was away racing the next week. A price was agreed, and given that I drove the bike 7 hours each way, thought it was reasonable.
After waiting 4 months, I finally get a time to pick it up with 2 weeks’ notice. However it seems like he is in a panic and rush. I get a few calls 2 days prior to pick up he says 'gee it’s a tight fit in there, I have just started to grind the frame to make it fit'
You What????? I replied. Please Stop!!! I said I will be there the next morning don’t touch it until I get there. Unfortunately when I got there he had ‘finished’ so to speak???
The result was a long way from my expectation. It wasn’t fitted at all, and to my eye, and my friend with me, it was twisted. The fellow said 'Just get a G clamp on it and it will bend back . . .'
I think he made a simple mistake. He extended the swing arm first, welded it up in a jig / welding bench, but it needed to be narrowed 20mm to fit in the RG frame at the swing arm pivot. Once he cut and welded the swing arm the second time it wasn’t in a jig and as a result its twisted.
Rather than argue, I sucked it up knowing I had done my cash. As we loaded the bike in the back of the Land Rover he then says I owe him an additional $200 for machining. Unbelievable!!! Given I had 2 swing arms, travelling expenses, the agreed price, the additional $200 it works out to about $1200 to make the steel swing arm unusable. Sad part is I lost 4 months in the process.
It has taken a bit of the wind out of my sails at the moment. It now sits in the shed and I will get back to it in the coming weeks.
Such is Life 'eh!!! _________________ I'm not a complete idiot - Some parts are missing |

Thanks for the support
The grinding was on the back of the footpeg exhaust carriers and it was about 2mm worth of thickness. It has been dressed up and it is hard to tell now. It was the principle of it that annoyed me the most. I was VERY clear on not touching the frame.
It will get back on target. I still have both ends of the second DR600 steel swing arm here as I took all the bits when I picked it up. Thinking I may get some 2mm sheet bent into box seciton for welding, then bracing. Build my own jig which is what I should have done in the first place.
I am getting back into it and agree it will be a great little bike once its built!!! _________________ I'm not a complete idiot - Some parts are missing |

Ok, dust has settled and I am back at it again!!!
Now working on the front end and will get back to the swing arm a little later.
Just pressed the stem out of the DR600 triples and about to start measuring up to make a new stem. I will lower the bottom triple clamp about 20mm to clear the radiator and give more steering lock.
Question is what are the steering head bearing numbers for the RG250?
I will run the same bearings but need the lower bearing dimensions.
Looking at the DRZ400 front wheel hub and it looks identical to the DR600 so hopefully I will mean just a change of wheel bearings . . . . .

Just picked up some 4140 - 38.1mm x 400mm ready to start machining the steering stem. Cost $22.60
Here is the stem design I have come up with
