Lately, us middle-aged guys have gotten the motorcycle bug again.
So what’s the hot topic everyone wants to know about? Basically, what’s the deal with this thing? I think a lot of people are wondering.
Yoshimura slip-on Katana (19) B-77 Cyclone government-certified titanium pipe YOSHIMURA 110-199-8400
It’s a bit short and fat, but it might be a solid option?
Modern bikes can muffle sound quite a bit with those big catalytic converters underneath.
It’s been a while since I’ve seen one—it’s really thick, like a thud!
The inside is curved, so I measured the inner diameter of the punching end lightly.
About 48 mm—pretty nice.
The insertion diameter is a bit geeky.
62.47 mm, 62.5 mm. Since the tail pipe outer diameter is 62.0 mm, let’s call it 62 mm.
The banana shell outer diameter came out to 99.36 mm, about 100 mm.
Pretty voluminous.
You need this much volume to fit the wool insulation inside anyway.
Roughly speaking, it’s about 370 mm from the end to the insertion end.
Looks like it could match up with a lot of vintage bikes.
That’s Yoshimura for you.
They weld a patch first, then the bracket—building in extra area and easy recovery options if something goes wrong.
When you look at these little details, you can see the maker’s philosophy, and it’s really interesting.
The silencer alone has a part number, so I wonder if you can buy it separately?
