Some of you guys might find this interesting. I found some weights for ZX25R parts, the ZX6R exhaust, and took others from the N400.

Theoretical lowest street legal weight:

362.24 LBS
164.32 KG

If you find any accurate weights let me know and I'll add them in.

I imagine dropping the triple-cat exhaust should save a good chunk of weight.

A full titanium Akropovic system on this bike makes my pants tight.

What type of wheel did you take as the alternative from the Ninja 400? Forged aluminum?

when we actually get the bike and put in on a scale and for us race shops that know where to slim the weight off, we'll get some REAL #s out there

triple-cat exhaust

I don't think this bike has a cat, let alone three of them.

Usually in the service manuals they will reference this in the few opening pages, as well as identify them further on. Below are samples from the 2016 ZX-10R.

Then it will show the location of the cats:

I don't see either section in the ZX-4R service manual.

That's weird agree they do usually mention it in the service manual, but that internal sales flyer that came out definitely states they're there.

Looks like they're in the collector unfortunately, so going to need a full pipe to really uncork it.

Odd, interesting - missed that detail in the flyer, thanks for showing me!

But yeah, pretty odd to have them there, but not fully unexpected. I've seen a few Kaws where they are integrated inside there. Some of the older ZX-10Rs had them in there but those were easy enough to punch out. My old neighbors H2 SX had one large one in the collector but we cut the pipe off, drilled it out with a hole saw kit and fitted a MTQ link pipe between the stock header and the Kawi Akra canister to eliminate his. God that sucked, took a few hours to do properly. When I got my H2 SX, I said "F it" and just bought a full system for mine because that was a job I wasn't going to do twice! 🤣

The revised Yamaha triple's exhaust looks exactly like this as well, integrated cat housing at the collector. I assume they pushed it as far as they could toward the hot end for better efficiency.

I think this might actually be a Euro 5 or 5+ thing.

I remember hearing something about the rules meaning cats have to be a welded part of the exhaust system and not the can. Can't find a source for this though so don't quote me...

Could very well be.

 

[xorbe]

Same with the newest Street Triple that's coming, they stopped short of welding the headers to the block, surely it's Euro whatever.

Yes.

 

[misnblu]

Yes.

Me too.
Cant be mainstream with the black wheels on my N400 or the new 4RR.
How about some gold? 🤤🥰
GaleSpeed for the 4RR and MOS for the N400. 👍

Love'n da gold wheels

Interesting...5.5" rear but $2500

 

[SCracing]

I'm getting a set for another member and they're a lot less than 2500

These are what @Speedwerks is referring to and yes even on the Webike site they're similarly priced.

I'd seen these but abhor how they look and the fact they're black in color.
You know how I love the gold and that's what I'll be getting when that time comes. 👍
