If you want to try to soften (speed up) the compression, you should soften (speed up) the rebound too. Otherwise, the forks will compress, compress, compress, and not rebound until you are through the chop. The compressed forks have a compressed spring, and it feels harsh. Often, you should...

Unlike Tesla and BYD in the EV car world, and Stark and Surron in the EV moto world, nobody else is making any money on electric vehicles! And KTM simply cannot afford more losses. The good news is Stark has been making some money, last time I heard the news on the subject. And Tesla is making...

Deviating from the topic, sorry. But I just had an epiphany... You are absolutely right! I used to run 50% regen and I thought it was really good at Glen Helen when the track was wet and tacky. Then I switched to 40% and I thought it was better. Yesterday, at my local dry/hardpack/gravel track...

Do you know if they use the KTM Super Duke caliper bracket too?

45hp and 40% regen works for our local dry hardpack track. More hp only causes more rear wheelspin and slower corner exits. I reduced it from the old 50hp setting and started exiting the turns much faster with less tail wagging. It is all track and surface dependent though.

Wow! Look what I have found! Happy 6th anniversary! https://electricdirtriders.com/threads/trump-threatens-eu-with-retaliation-over-%E2%80%98unfair%E2%80%99-tariffs-on-harley-davidson.1050/

The US has imposed sanctions on itself. Putin loves it!

I used to complain about the on/off throttle. I think Stark Future has been reading because I too noticed that my Stark is now loading into my trailer just as smoothly as my Alta does! Also, I no longer have to shift to the 35 hp setting for flat dusty or gravely turns. Keeping the bike in the...

New segments is where the fast growth it. In the established segments you have to displace established companies, so any new product has to be either a lot better or a lot cheaper. In new segments you just have to have a product.

We used clutch master cylinders on the Alta. Now Stark has Brembo master cylinders with larger fluid reservoirs, which work better for brake application because they are less likely to become low on fluid and suck in air. But... does anyone know the Stark Brembo LHRB master cylinder piston...

Yeah, having a no-name reduced diameter and reduced travel suspension, despite having swappable racing batteries, will relegate these bikes to non-jumping, woods riding, and a few amateur competitive events. This is a very unfortunate product decision.

Thanks for the heads up. Filing this under its own special category: https://electricdirtriders.com/forums/the-fugly-charger.113/

These are the new Bonnell 40hp and 60hp dirt bikes. Here are the Electric dirt bikes: They also have 1200W mountain bikes that have throttles. These are electric mountain bikes: Thanks to @DonCox for the news!

Don't let any non-Stark owner see the title of this thread!

I see your point, you are right. I asked Grok again and the answer came out better tailored but still similar to what it said before. Its efficiency likely peaks (e.g., 94-96%) at a mid-range RPM (perhaps 5,000–7,000 RPM). https://grok.com/share/bGVnYWN5_51db0bfb-2da9-41d5-bda3-5920f132f68e

You have to run a computer simulation then! :-)

The "sweet spot" for PMSRMs, often occurs at a mid-range RPM (e.g., 3,000–6,000 RPM for automotive applications. https://grok.com/share/bGVnYWN5_9857d3c6-b356-4851-84f9-0b97f0b9cfbb This is 30-60 km/h for the Stark Varg. What is the average speed in your race?

Yeah, I saw that storage compartment on the Leopard. it's at the end of your video. The Alta has a huge empty space around the rear shock. But you'd need to design a special bag to fit there to use that space. The Stark has almost no empty space! Maybe someone could fit a cupholder somewhere...
