Kawasaki Z H2 Supercharged Streetfighter Bolt-on Swingarm Extensions

2020 Kawasaki Z H2 Supercharged Streetfighter Product Development Update: Bolt-on Swingarm Extensions Installations Video with Additional Considerations Discussion.

Bolt-on swingarm extensions are a quick/easy/economical what to safely increase the wheelbase of most motorcycles so as to increase high-speed stability and decrease wheelies for quicker E.T.s at the drag strip – BONUS… stretched bikes look MUCH COOLER!

Now, before we hear from the “OMG…why-Why-WHY would you ruin the look and handling of such a fantastic machine?!" Gallery, please remember this video is not intended for you. We will address riding a 220+ RWHP sportbike with a 57” wheelbase soon enough.

For those interested in the benefits of a longer wheelbase, regardless of which make/model you ride, please watch on as Brock not only discusses the proper installation techniques in regard to bolt-on extensions, but he also outlines additional considerations to address while doing so. Having all of your “ducks in a row,” as they say can help alleviate frustration as well as additional downtime.

Hello! Brock, i would like to clarify a thing about the Loctite you are using ( i do not think that the blue bottle is pure brand Loctite but anyway )
the thread locker is an anaerobic adhesive that applies in drops to the threads of fasteners. It then polymerizes into a thermosetting plastic which blocks the threaded assembly. These products can only be used to fix metal to metal.
it will only hardened in absence of air and metal oxidation, you can leave the liquid on the table and it wil not hardened.That is why the bottle seam half full when you buy it, it needs air to stay liquid, also a good practice is to not touch the bolt with the tip of the bottle since any metal particule will activate it, just let the drop fall on the thread.
As for the red color you need to heat it good to soften it to be able to remove the bolt or nut.

Easier than the XL spreadsheet is a website called gear commander, they have a pile of different bikes with all the factory information and allows you to modify stuff and see the difference.

Got a kick out of the attack dog guarding against someone inadvertently pumping the brake lever/pedal with the caliper off. Got extensions on a Suzuki B-king...worthwhile addition for putting the power down and keeping the drama factor at a minimum. Great vid.

If I trust you to do that on my Z H2, I trust you with my life, and I would. Excellent work and presentation.

Man I absolutely love your channel. And I found a full Brocks exhaust for my 2012 Ninja 1000. I haven't purchased it yet because of financial reasons 😔 but I am saving for it and I can't wait. But you always go into great detail when you are doing something and I really like that.

The late great David O. Still think about him all the time...

[jakeviveros]

The wide-open throttle Power restriction blows my mind. But the fact that Brock says big brother says nope, nope, nope, is hilarious so true.

I have been installing some of your products and enjoying the videos. When i was installing the extensions on the 2020 H2 they came without instructions and at the time i could not find anything online. I spent some time and removed the stock brake stay because the tire was extremely close to the stock brake stay and i was concerned that as the tire heats and expands it could possible rub or someone could decide to run a wider tire or tire with a different profile and it probably would make contact. I was trying to make the safest decision and talked to the customer about it first. The owner of the bike said it was for track use only and he had no intention of ever going back to stock wheel base. Once again great videos and some good tips.

I installed the swingarms extensions truly makes a difference. Very happy!

just installed new tires on my z900rs and was surprised how the rear brake pads had to hit the clip in the front. First time I installed, I missed the inside just like Brock was showing us. Realized it before I tightened it down and corrected it so both brake pads were in the clip. That was a bit of a shocker for me how that's designed. Less weight I guess!

Cool video. 4 inches is a lot. Most people might not think so. But it is. Specially if your doing track days and adjusting your bike. People would be surprised how bikes react to being adjusted.

Brock, you are always up to something new. Always improving. These swingarm extenders, are they bike specific or will they work on a Gen 5, 2017 ZX-10RR? I like the efficiency of these verse having to swap an entire swingarm. And the brake line extension and speed sensor extension, are these universal or for Z H2 only?

[jeremybly]

I had to re-watch the Swingarm break like 10x lol
