No More Worries? A Thing of the Past? “GSX1200S Inazuma Oil-Cooled Katana” JB1 Mag Tank Tire Change Swingarm Overhaul and More

Two-shock suspension is easy and nice♪

The Inazuma 1200 is
a center stand is optional.

My Inazuma has
of course it’s equipped!
It’s a world for enthusiasts…

Time passes

Check swingarm width
Assemble everything and install

“Hmm? There’s a lot of play?”
This is a common occurrence with swingarm assembly
*Old bikes only

If you don’t have optional shims ready
it’s probably going to be loose
Well, it’s probably fine anyway…

It’s faster to assemble the swingarm components individually
and check them.

Breaking out the crown jewels

Using KEEP parts.
No point in stockpiling!
Everyone should use them freely.

Going with BITO for the pivot shaft!

Going with Honda for the rear suspension lower side

BITO uses OEM parts so returning the Marque ones

And that’s how the undercarriage is complete.

Full of holes?

The fenderless looks like it might break…
or so they say.

Motorcycle aftermarket parts
don’t last that long…
Especially FRP/aluminum products
And rigid mounting? That’s impossible



One shot reach!…

The weight of the license plate and tail light
“It all comes down to full throttle”
It held up well! Impressive!

Let’s give it praise


Sheared and bent SUS plate

The price of custom work isn’t market rate
“time = labor cost”

Whether it’s just temporary or done right
Whether it causes problems later

I’m worrying about it on my own and moving forward.


It’s tedious

Because all the hole positions are sloppy
Sloppy doesn’t mean good
it doesn’t…

I want to finish it… but

That’s when I mess up at the end.
Wondering whether to make it super strong
Tomorrow I’ll drill the holes…
