ZX4R Weight Saving

GUWOP · Mar 10, 2023

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

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! 🤣

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...

ME-Motorsports · Mar 10, 2023

Could very well be.

xorbe · Mar 10, 2023

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

Interesting...5.5" rear but $2500

SCracing · Mar 14, 2023

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

50 · Mar 14, 2023

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. 👍

This web store has ruined my wallet and made my day;

That website poses a risk to my financial health.

The titanium axles are sweeeeet. 🤤
Nice site but no translation that I can see. 😖
My wallet is hollering to stop so I will, for now. 🫢🤫

kaanivore · Mar 21, 2023

God I want the whole bike in Kawi lime carbon fibre

It is time to revive this thread! Who knows what their bike weight is?

AV80R · Nov 22, 2023

385 lbs in street trim with fuel at the top of the filler neck and oil at the top line of the sight glass.

I will put mine on the scales later this afternoon.

Chuck Graves · Nov 23, 2023

My bike weighed in at 361.5 without fuel. I thought it would be better to go dry because measuring to the filler neck seemed less accurate. I’ll post a video of it on the scales. Time to put this unit on a diet!

does any1 have a link to a document / video for the charcoal Canister delete ?

Post #251 in this thread has some photos and commentary that might be helpful: https://www.zx4rforum.com/threads/av80r-zx-4rr-build-thread.763/page-13#post-9463

A Kawasaki 92068-006 vacuum plug is all you need to buy to remove the canister from the bike.

Romad · Dec 13, 2023

Also here, but a vaccuum cap and some long reach pliers is basically it
