MotoGP Rubber = Better Climbing?

April 14, 2026 by Ian Bos 15 Comments

Walking on grass, it’s easy, no matter the shoe. How about an inclined trail? Some hiking shoes or nice tennis shoes will do the trick. How about climbing a mountain? Now we are gonna need something special. [Magnus Midtbø] is a professional climber with an acute awareness of this fact and has used shoes of all kinds; however, today is something special.

Imagine if you could use the technology of MotoGP to give you the same grip as a 1-liter bike. That is exactly what he tried out. RAToM is a company that has started to market a unique product, recycled MotoGP tires. Viral vids of this rubber being used have been going around with shoes even being able to stick to themselves. He decided to put it to the test by requesting some of this special rubber stock and applying it to his own shoes.

After extensive, though simple, testing along the bouldering wall he admitted to the effectiveness of the special soled shoes. This shouldn’t be too surprising with MotoGP’s intensive material science innovations involving their tire material. These tires include a variety of additives, from silicone dioxide to the traditional carbon black. What has not been able to be tested to its required extent is the durability of the material over long periods of bouldering.

Even though most of this specialized rubber material is primarily supplied by one company, the source material is recycled from any used MotoGP tire. This could mean DIY alternatives better than the current leading shoes could be possible with sufficient care if you get a hold of a tire or two… While this would not be an easy process, don’t be too scared to try! Maybe you could learn a thing or two from this case study on homebrewing a running shoe!

Hand Truck Turned Into Motorcycle

May 27, 2025 by Bryan Cockfield 13 Comments

For those motorcyclists looking to get a classic American-style cruiser, often the go-to brand is Harley-Davidson. However, these bikes not only have reputations for being stuck in the past, both in terms of design and culture, but they also tend to be extremely expensive—not only upfront, but in maintenance as well. If you want the style without all of that baggage, you might want to try out something like this custom motorcycle which not only looks the part, it reduces those costs by being built around a hand truck.

By the end of the project, though, the hand truck does not retain much of its original form or function. [Garage Avenger] has cut and welded it essentially into a custom frame for the diminutive motorcycle, while retaining much of its original look and feel. Keeping up with the costs savings aspect of this project, the four-stroke engine was free, although it did take some wrenching to get it running and integrated into the frame. A custom axle, a front end from another bike, a gas tank from an online retailer (that needed re-welding), and some wiring finishes out the build.

With a fresh paint job to match the original color of the hand truck, it’s off to the track. Of course it doesn’t have quite the performance of most street legal motorcycles, including some quirks with the handling and braking, but for the trails around [Garage Avenger]’s home it’s certainly a fun transportation mode he can add to his repertoire. If this is your first time seeing one of his projects, be sure to check out his other work including this drifting shopping cart and this turbine-powered sled.

How To Cast Silicone Bike Bits

April 26, 2024 by Jenny List 23 Comments

It’s a sad fact of owning older machinery, that no matter how much care is lavished upon your pride and joy, the inexorable march of time takes its toll upon some of the parts. [Jason Scatena] knows this only too well, he’s got a 1976 Honda CJ360 twin, and the rubber bushes that secure its side panels are perished. New ones are hard to come by at a sensible price, so he set about casting his own in silicone.

Naturally this story is of particular interest to owners of old motorcycles, but the techniques should be worth a read to anyone, as we see how he refined his 3D printed mold design and then how he used mica powder to give the clear silicone its black colour. The final buses certainly look the part especially when fitted to the bike frame, and we hope they’ll keep those Honda side panels in place for decades to come. Where this is being written there’s a CB400F in storage, for which we’ll have to remember this project when it’s time to reactivate it.

If fettling old bikes is your thing then we hope you’re in good company here, however we’re unsure that many of you will have restored the parts bin for an entire marque.

Shôtarô Kaneda’s Motorcycle, For Real

March 17, 2024 by Jenny List 25 Comments

For fans of the iconic anime Akira, there’s only one way to traverse the mean streets of post-apocalyptic neo-Tokyo, and that’s the futuristic mount of motorcycle gang leader Shôtarô Kaneda. It’s a low-down feet-forward machine with, we’re told, “Ceramic double-rotor two-wheel drive,” which we’re guessing is some kind of hybrid electric drive with what sounds like a gas-turbine motor. Over the years, there have been a few different attempts to create a real version of Kaneda’s bike, and we’re pleased to see the latest from ヲタ工房「ポンちゃンネル」(Ota Kobo “Ponchanner”). It uses a twin-cylinder Kawasaki motor in an entirely custom-made frame, with dual single-sided swingarms front and rear and hub-centre steering.

The full build in the video below the break is pretty long but well worth a watch, and it includes a lot of very highly skilled metalwork. It’s an interesting choice not to attempt to make a direct replica of Kaneda’s bike. Still, we think some of the differences are dictated by this being very much a roadworthy and everyday-rideable machine.

Ride DIY Or Die This Badge-Less Suzuki

July 3, 2022 by Kristina Panos 12 Comments

A few years ago, [Charles] picked up a sweet Suzuki motorcycle that checked all the boxen: it was in good shape, bore a few useful upgrades and a box of spare parts, plus the price was right. Though he assumed that he had pored over every picture on the classified site before buying, it wasn’t until later that [Charles] realized that something was indeed missing from the bike — a piece of chrome that does little more than to cover the tee in the brake line and bear the Suzuki brand. Once he saw the problem, he couldn’t un-see it, you know? And at that point, he just had to have that little piece, even if he had to make it himself.

That wasn’t the original plan, of course, but bike parts are expensive to begin with and only get worse as size, condition, and rarity increase. [Charles]’ quest to find this piece was halfway successful; he found a reasonable-but-rusty facsimile of the right part, although the emblem portion was long gone. Then he remembered the wife’s vinyl cutter.

Now, let’s stop right there. If you know anything at all about these vinyl cutters, you know that they are basically glorified 2D plotters with a knife attached where a pen would be. Send it any 2D file and you’re good? No, no; of course not. These things are locked down by the manufacturers.

Fortunately, [Charles] found inkscape-silhouette, which makes light work of sending SVGs to the machine. After much back and forth and maybe a bit of coin-flipping, [Charles] settled on the classy, stylized ‘S’ version rather than the full-on Suzuki badge. We think it looks great, and we’ll never tell anyone.

While this isn’t quite the type of badge we’d normally talk about, it’s a great project nonetheless, and it’s always nice to hear about projects that open up otherwise closed-source hardware.

There’s A LEGO Suspension Dyno Now

June 16, 2022 by Zoe Skyforest 1 Comment

When it comes to the development and testing of performance suspension, it’s helpful to have a test apparatus that lets you recreate certain conditions reliably. This LEGO suspension dyno does just that, and it’s clearly a big help for those doing R&D on minifig motorcycle suspension.

The build relies on four motors to overcome the resistance of turning a chunky conveyor belt, which acts as a rolling road. As the belt is built out of Technic beams, various LEGO blocks can be added to the conveyor to act as bumps or perturbations for testing suspension.

The video demonstrates the use of the dynamometer, showing how a simple LEGO motorbike design deals with bumps of various sizes. It’s easy to swap out forks and springs and change the geometry to tune the suspension, and the changes can be easily seen when running it through the same test conditions.

While we don’t imagine there are too many people working in this particular field, the lessons being taught here are valuable. This setup allows one to quickly visualize how changing vehicle parameters affects handling. It’s hard to imagine a better teaching tool for vehicle dynamics than something like this that lets you see directly what’s really going on!

Motorcycle Regulator By Popular Demand

May 23, 2022 by Bryan Cockfield 23 Comments

A few weeks ago we posted a build of an avid motorcycle enthusiast named [fvfilippetti] who created a voltage regulator essentially from the ground up. While this was a popular build, the regulator only works for a small subset of motorcycles. This had a large number of readers clamoring for a more common three-phase regulator as well. Normally we wouldn’t expect someone to drop everything they’re doing and start working on a brand new project based on the comments here, but that’s exactly what he’s done.

It’s important to note that the solutions he has developed are currently only in the simulation phase, but they show promise in SPICE models. There are actually two schematics available for those who would like to continue his open-source project. Compared to shunt-type regulators, these have some advantages. Besides being open-source, they do not load the engine when the battery is fully charged, which improves efficiency. The only downside is that they have have added complexity as they can’t open this circuit except under specific situations, which requires a specific type of switch.

All in all, this is an excellent step on the way to a true prototype and eventual replacement of the often lackluster regulators found on motorcycles from Aprilia to Zero. We hope to see it further developed for all of the motorcycle riders out there who have been sidelined by this seemingly simple part. And if you missed it the first time around, here is the working regulator for his Bajaj NS200.
