Well then, everyone’s favorite Inazuma 1200 here.
When I looked into it a bit, the number of used bikes has really decreased.
Did it become a sword or something…? I wonder what’s really going on.
On weekends, with the weather being just right, I’ll steadily work on this project.
I’m converting the rear disc from the OEM 240φ to 220φ using a stock conversion method.


A gem? Suzuki 69721-35F00 Rear caliper support. *Discontinued
Suzuki GSX-R1000K1 and various other models used this 220φ support.
This support is built quite robustly, so rear vibration and noise should be less likely to occur.
This support has a 28φ rear axle compatibility.
With a convex collar converting it to 20φ, it becomes adaptable like this. (*´ω`*)Whoa!
I made a press-fit collar from A7075.




The 75 cuts so cleanly, I was lost in the moment… *It was just that I didn’t have 17 in stock.
With poor setup, it took about an hour and a half for this machining.
That’s the level of my skills.


Heat it up in the oven until it’s hot, “Pop!” (*´ω`*)
And the support is complete.
There’s a possibility that wheel casting burrs could contact the rear caliper, so it needs checking.
I’m making a torque rod from GSX-R750/1100 aluminum rib material.


This is something I did before on my own Inazuma 1200, a popular? topic right.
I love subtle adaptation work that nobody notices.
This is a new? bending angle for me, so I’ll redo the bend.


Since this is the only material I have, failure is not an option.
(;゚∀゚)=3 Panting I successfully completed the bend.
Next is to cut and create the legs.
Like the GSX-R original, I’ll cut it “herringbone” style to increase the weld surface.


The herringbone is alternating, which might be the trick? I guess. Well, I just did it the same way (´ー`)




Tire clearance is good. Even with front and rear chain adjustment, there should be no issues.
OK! Google (*´ω`*)
I’m doing a swingarm overhaul.




Even in a gap like this, it fits “Wheel Lifter” A reliable tool.
You can remove and install wheels at waist height, and the collar won’t fall off—it’s the best (*´ω`*)
Work has become so much smoother.
Without a doubt, “This Year’s Best Buy” will include this.
The pivot shaft is integrated and won’t come out.


Initially, the shaft itself was biting into the frame and wouldn’t turn.
With proper lubrication and love, it now spins smoothly, but…
“There’s still not enough love,” it seems, and it won’t come out even 1mm ( ;∀;)
Basically, it’s better not to hit the shaft directly.
*Burrs can form or threads can get messed up. Let’s be prepared just in case.
Hit it hard with a punch and screw it in tight.


I welded an unnecessary axle shaft to the pivot nut and hit it hard and powerfully!
Unfortunately, there’s still not enough love…
I’ll lubricate it and wrestle with it another day. Let me swap the cam first… Phew~ (*´ω`*)
