Show me an actual drag bike with an aliexpress extended swingarm bolt on. I wasn't aware that they could really take that sort of load.

Ok so this post made me go look at the pictures more closely and holy gently caress!

The 'right' way to do it is to cut your swingarm and weld in extensions and any necessary bracing. This works well for low powered bikes. If you're making real power it's more sensible to just build a long swingarm from scratch.



What the above turds have got, I have just understood, are bolt on swingarm extensions. I don't know where to begin, it's a war crime even KTM's don't deserve.

The axle and chain adjuster casting can't possibly cope with a foot long lever being bolted to it, there is no multiple bolts or bracing or anything, which means they're relying on a tight interlock between the parts + the axle bolt holes, which means the swingarm now has a hinge in the middle.

The extenders are separate to one another so they can flex independently, what this will look like is the back wheel cambering over toward the sprocket side, as well as the whole swingarm just flexing side to side and giving you a hella weave that probably counteracts any gains from the longer wheelbase. Idk what a corkscrew shaped bike does to your ability to keep going straight.

All of this will lead to rapid work hardening and eventual failure of the factory swingarm which is definitely not designed to take those types of forces in that kind of direction.

In short: :psyboom:

It brings me innumerable joy to witness another soul realizing the horror that is the typical "extended swingarm".

Is just the icing on the cake that comes from informing slavvy of this horror. It's just a mod that ignores physics or torque or like basic things that we should all understand in preschool. Like these morons never grasped a seesaw I guess.

And it's totally cool that they are trusting their lives to an impossibly overspecced bit of mass produced anodized slag aluminum produced by people who care not for legal repercussions.

But it costs less than $400 usd and that has to be less than what a complete swingarm costs so it's a win!

I would like to take this moment to applaud Suzuki for not attempting to integrate an extended style swingarm into the new Hayabusa design language. I'll bet there were some concept sketches.

They're very conscious of what the aftermarket is doing; with the latest revision they improved the lubrication system, gearbox etc to account for people expecting 500+ reliable horsepower with a turbo. It's likely they've improved the relevant frame areas on the bike to account for people bolting on huge swingarms. I think at one point if they had sold an off-road only genuine Suzuki extended swingarm they could've made mega bucks, but they're now so ubiquitous in the aftermarket there'd be no point.

Oh, there's no doubt they're aware. But it would have been easy to say "this is what the cool kids are doing to our product, if we make it look like that, think of the sales!". Happens all the time with cars. I think that to say no to that urge, build a normal bike with maybe a tacit nod that says "we know what you're going to do with this bike once you get your filthy hands on it", with the understanding that that's what drives the interest, the cult culture, and the ultimately the sales, is a wiser approach.

Maybe they got in trouble and now they're just looking to do quasi-hooligan (grom) poo poo instead of actual hooligan (sumo) poo poo or they simply want something different (and dumb) in the garage


In a similar vein, I'd be willing to take a good e-bike in trade towards my FZ09 from a pure practicality standpoint. I still have two other bikes and frankly I could use the extra garage space

Hi Brady, you know how in precision optics, such as things like space telescopes, and extremely precise lenses they have to do absolutely crazy things like grind the glass against surfaces who’s flatness is measured in literal atoms? And you know how they have to grind the lenses in special rooms that are completely free of dust and other contaminants because even one mote of dust will throw the overall flatness off by orders of magnitude? And of course that’s to say nothing of smoothness vs flatness. Smoothness on these lenses is verified with scanning electron microscopes that ensure that there are no ripples in the glass larger than nanometers over the length of it.

The flatness and especially smoothness of these lenses are absolutely unparalleled the world over, and requires a team of scientists and engineers to work for months in absolutely sterile, controlled conditions to achieve smoothness on the sub-atomic level.

That’s how smooth your brain is.

I bet that thing rides really spooky, like a bike with worn swingarm bearings or a chain adjuster than won't stay tight. Those swingarm extensions scare the poo poo out of me for all the reasons Slaavy listed. To make that even remotely safe there should be additional bracing above and below the swing arm that ties both sides AND the rear bolted on extensions together. I don't want to use any extended swingarm as a good example but something more like this where there the builder was at least aware of the concept of torsion:



At the very least the whole thing is welded together and not bolted.

Real extended swingarms that are made for drag racing are always a one piece design in my experience. Usually with extra bracing like above.

The extender inserts are specifically for Hard Parking™️ at bike night

I know the local drag track, Great Lakes Dragaway, won’t let your bike pass safety if you show up with those extender inserts.

Extender inserts are pretty funny and still dangerous on a Vitpillen with 400cc’s but they become a legit danger to everyone around if someone shows up with them on a Hayabusa or ZX14 or something like that.

Dang glad I stumbled on some cool Moto history with this ad.

The FXR is considered one of the best Harleys on the road, but this wasn’t always the case. In fact, when it was first launched in 1982, people seemed to consider it too Japanese.

Aha this is why it’s so good.
