Yamaha Teases Electromagnetic Steering Damper

Last week was the opening of 2023's Japan Mobility Show, a showcase of novel and futuristic mobility concepts that may or may not see production down the line. Though the potential reality of these designs is uncertain, the concepts behind them are quite real, so there are always interesting morsels to pull out of the displays. Amongst the utopian array of motorcycles, electric cars, and e-bikes, Yamaha's Y-00Z MTB looks fairly close to a real-life concept, albeit probably still far from production.

The feature that stood out to me on the Y-00Z is the steering damper. In their literature for the event, Yamaha refers to this as an "Electric Power Steering system," and it utilizes a device called a magnetostrictive torque sensor. Magnetostriction is a very cool principle within physics, and is a property of magnetic materials by which they can slightly change shape due to variances in the applied magnetic field. The results of this change are highly accurate, repeatable, and can be done without direct contact. The principle is absolutely position sensitive, and theoretically has no wear on the magnetic element. The only active part is that which generates the electric signal, making for a relatively simple object compared to some mechanical solutions to the same problem.

Essentially this would be the device installed, with the "shaft" representing the steer tube of the fork.

All packaged in that little doodad under the stem. Pardon the potato photo quality here.

Yamaha already employs this in some of their motocross and superbikes, fitting the system to a couple YZ450F and YZ250F motocross bikes. The theories behind the handling of a fully-powered moto and those of a powerful eMTB aren't terribly dissimilar, so the crossover makes sense to me. No news on whether this will make it to market, but we reached out to Yamaha to see about procuring a device to try out. Stay tuned.


That's not the only bike Yamaha brought to the show though, there was also a very special monstrosity that they're calling the Y-01W AWD. This drop-and-aero bar two wheel drive fat tire inverted fork rack-equipped dropper post e-bike is truly a sight to behold, and probably gets you to your coffee outside meetup faster than anyone else.

While the steering damper is quite intriguing, and the all-terrain commuter bike is sure to take the market by storm, there's one other invention in the Yamaha booth that really has my heart: the Rock On Me rideable music machine.

photo

Upon further investigation, I fear the speaker stack in the undercarriage is actually just some jingle bells, but in my mind they're powerful speakers that blast you with music as you rock back and forth. Make that in an adult size and you have at least one customer right here.


That's all for now, thank you for tuning into the first episode of Dario's Online Miscellanea Hour.

 Rumor is this bike was built for Eli Tomac’s switch to E-MTB & MTB after his retirement from Supercross at the end of the 2024 season. I hear John requested the drop-bar gravel bike for the dirt roads around the Tomacs’ Cortez compound. As for the rocking moto, it’s for Eli’s 2yo and 3yo kids...and plays 4-stroke sounds from those speakers. The E-MTB even looks like his KYB-suspended Supercross moto:

 @WRCDH: when is Dunlop jumping into mtb tires?
  • 20 0
 @ReformedRoadie: They’re still working of the surface morphology of their nano-diamond / micro-diamond friction particles...Japan has very demanding wet roots and slick red volcanic mud, so they’re still optimizing the friction and mud-shredding properties of their rubber and MTB prototype tires. With the right micro-diamond surface area / surface roughness / surface functionalization (and thus crosslinking into the vulcanized rubber), the diamond provides durable grip and mud performance without shedding the diamond particles. Apparently their graphene + diamond (both carbon) modification of their synthetic rubber is called “E-Lasti-C/C” or “ELastiCC” for e-bike-capable long-lasting elastic carbon/carbon modified rubber. I’m guessing it will be 18-24 months before it hits the market.

 @WRCDH:
I can’t tell if this is serious or not, but I remember being at a Fontana race that happened to coincide with a Superbike race at the raceway. During breakfast at the hotel the Dunlop tire techs noticed us wheeling our bikes out to the car and came over to chat. They spent about 20 minutes asking us about casing, compound, tread, and what we did and didn’t like about current tires. That was over 10 and I always wondered how serious that conversation was and if they would ever get into the game.

 @FloriLori: What's that got to do with it? I've got a bunch of coils and magnets inside my Shimano Nexus front hub (of my commuter). When I ride, both front and rear light go on. The motor in that bike is probably much heavier so it could provide a lot more resistance, hence also charge the battery. You only have to pedal a bit harder, that's all. But if the goal is to charge the battery, it can be done.

 I feel like we are slowly reinventing motorcycles at a higher price point, while gutting the sport we all fell in love with years ago. And before you say don’t buy it, just know that I can only buy what is available. All brands stopped making 26ers years ago and most stopped on 27.5 now. Kinda hard to vote with my wallet when I’m being pushed to choose between vanilla or vanilla.

 Banshee Spitfire is still being made and is set up for 26ers. Even has modern geo. Go buy one.

 This is my main complaint about ebikes in general. This evolution happened before, we all want ALL the power if it's powered. And it shouldn't cost this much. When a bicycle costs what a Ducati motorcycle does its gotten insane. Let's keep bicycles as bicycles.
  • 2 0
 Your argument doesn’t check out; what’s the equivalence between wheel size and electrification of bikes?
  • 2 1
 @blackthorne: I was just preemptively rebutting the played out “vote with your wallet” claim. I agree with you that adding a motor is not the same as changing the handlebar diameter, but the point was if they primarily only make 29er and Mx bikes how can I vote for 26ers? Ofc someone was quit to point out there are still 1 or 2 remaining options, but the point remains that the industry is pushing the tech and not the consumer.

Did we beg for cables through the headset for years and then the industry caved? Or was it that we opposed it and they pushed it anyways? In 5 yrs will there be just 1 or 2 hold out brands not doing cables through the headset?
Are we still going to have a choice for cable actuated drivetrains?

Thanks for your response.

 This is the part that caught my eye. It's like a Rocky Mountain system but with none of the ridiculous chain retention wokeness and two fingers up to chordal action. That 8 tooth drive sprocket and the 60 degrees of chain-wrap on the front ring will be plenty....

 @PhillipJ: Not a prank, what I thought was fairly obvious sarcasm, of course you want chain retention, and of course you want to avoid the chordal action associated with such a small drive sprocket, having a chain under motor AND rider load on an 8 tooth (therefore essentially octagonal) sprocket, is dubious as hell.

 Steering dampers have been used in moto for a LONG time and those dampers really do work wonders. I understand people are upset about more "innovation" but this is a legitimately decent product if it works well and as intended.

 I spoke too soon. When looking for a new headset I discovered the cane creek viscoset, a hydraulic steering damper.
  • 1 0
 @endoplasmicreticulum: There is also the Hopey steering damper, which is hydraulic, and has been around for ages (20ish years). If I remember correctly, it's a clever design, where the steering is only damped as it moves away from center, but is not damped on the return. Some DH riders used it in the early 2000s, but that was back when head tube angles were a lot steeper, so I think modern geometry may lessen the need for added stability.
