I had looked at their FAQ, I was not able to find the weight. I wonder how heavy it is compared with gasoline bike with fuel. Looking up the Suzuki GSX-R10002026 Suzuki GSX-R1000R boasts around 207 horsepower, slightly less than the previous model's 199-202 hp range depending on the region. Weight 202 kg (445.0 lb.). Range falls within 150-200 mile (240-320 km). Cost is about $19,000 USD.https://suzukicycles.com/sportbike

content: The Honda WN7 is available for pre-order NOW from dealers in the UK starting at £12,999 for delivery early 2026. Range is 80 miles or so.https://hondanews.eu/eu/fi/motorcycles/media/pressreleases/546687/confirmed-name-production-timing-and-major-specification-details-for-the-honda-wn7-its-first-electriOnce the range of these bikes goes above 150 miles and comes down in price, I might consider one myself. I can get 240 miles per tank using my RE Himalayan 411, and my EBike (pedal assist bicycle) has a range of 100 miles max (practical 50 miles to be safe). The Honda would have to get close to these figures for me to sell every bike and switch over. I do like electric bikes as they are less costly to maintain.

content: Quote from: joeqsmith on September 26, 2025, 12:35:22 am200 horsepower? That's 147100 watts of power. So I'm calling BS on it being able to deliver that much power (or handle that much heat dissipation) for more than a fraction of a second. I'll leave it to others to do the math to see how many batteries that amount of power would take, even if for just one minute of operating time. While you're at it you can also speculate on the operating voltage and current that would be required and how they would be able to manage that. And the claimed 200 mile range means that the batteries would have to deliver high levels of power for a minimum of an hour (assuming that you're driving at 200 MPH).And the ad looks more like they're trying to draw investors than sell products so I think that this is nothing but vaporware.Just for a comparison point, I wonder how much horsepower a full size electric car such as a Tesla model Y produces? And those weight over 6000 pounds.Also how big would an electric motor have to be to deliver 200 horsepower today? In my day they would have been massive!Torque is not horsepower so don't even go there.

Mine had the 440 cu in HP2 engine with three Holley two barrel carburetors and when you put your foot into it, you could literally watch the gas gauge drop! They put a 20 gallon fuel tank in it for a reason!

content: Quote from: joeqsmith on September 26, 2025, 12:35:22 amI'd love to take one of those for a ride too. But honestly I don't know where you get anywhere near the full potential out of it. Most of the roads in the eastern US are way too crowded and are over absolutely flowing with clueless drivers. I stopped riding a bike about 20 years ago due to how many times I was cut off or people pulled out in front of me or did other stupid shit. Florida also recently imposed a Super Speeder law and are VERY aggressively going after drivers that drive in excess of 100 MPH. It is now a Criminal (not Civil) Offense and they will now they will arrest you and immediately take you to jail and impound your car on the first offense and the penalties are very severe including possibly jail time and/or losing your driver's license for the first offense.

content: Quote from: Stray Electron on September 28, 2025, 04:29:33 pmFor sure on an NMC or other Li-ion is not going to do that. But if they have LFP or LTO battery, probably it can deliver that for some time, 10C rating is typical. They say battery is 20KWh, power is 150KW.I'm also guessing that it reaches it's top speed in less than 20s, and going uphill full speed isn't going to be a practical consideration for the engineers.

content: Quote from: tszaboo on September 29, 2025, 01:24:53 pm8 to 10C rating is also typical to NMC or NCA power tool cells. You are probably thinking charging power; the asymmetry between charge and discharge is somewhat worse on NMC/NCA. LFP (and especially LTO, but that has crap energy density) give somewhat better gravimetric power densityon charge, especially near full state-of-charge. But for discharge, power density of LFP isn't better at all, unless you do apples and oranges comparison and pick a energy (non-power) optimized NMC/NCA cell and compare that to power-optimized LFP cell.150kW from a 20kWh pack is "just" 7.5C and we are definitely talking about peak power, any li-ion chemistry type can deliver that just fine, given the correct geometry (power-optimized like power tool cells).And yeah, headline specs rarely all hold at the same time. This is usual for any tech.
