EX: Traction control and whiskey throttle for Enduro

[OpaTsupa]

First, some disclaimers.

- I know nothing about how throttle technically works on the Varg. I've not ridden the bike yet.
- I've never ridden Motocross. All my interest and experience is in the type of Enduro that is very different from MX terrain and riding style.
- I'm from the school of CLUTCH = CRUTCH. Throttle control is everything.

To get whiskey throttle, or "Doing a Taddy", out of the way first.
I keep imagining a simple software-rev-limiter that will cut the power if throttle is violently opened in an inconsistent manner. Ideally it would be smart enough not to cut in if riding aggressively, and only when there is an anomaly. That part is likely not so simple to design and implement.

Only time I do a whiskey throttle is when the handlebar is violently deflected by an obstacle, or mid-way trough the crash. It's not a major issue for me even with a lively 300cc 2T, but if technology is there it sure would be nice to have it.

For 'Traction Control' I don't mean just a sensor that monitors rear wheel spin, but the whole connection of engine characteristic, throttle, power delivery at driveshaft, gearing etc.
In my experience with ICE carburate bikes a minute change to any of these parameters (one tooth of the sprocket, one clip of the carb needle, different gasket/head etc.) can make a difference from suffering and fighting the bike to gliding over terrain as if on rails.
I would expect that a machine like the Varg can eclipse all that in terms of control and fine tuning.
Making something that works for every possible terrain and topography is unlikely, but a combination of a good Factory concept with enough end-user adjustability may be the key.

Power delivery that can automatically adapt from high output, continues drive and no wheel spin for a long, choppy hill climb;
Then maybe full power for the flat plateau section;
Then zero power, max engine braking for the steep decent.
That's stuff of my dreams.

So, the question is will Stark focus on developing the best Enduro machine ever or chase numbers flashy numbers like "80HP" that are not so relevant for Enduro?

Ok, so imagine you are writing the software for this. Did the rider really want to do that or was that an "inadvertent input"? Remeber, you are blind and cannot see if what object is in front of the bike; another bike or a log...

Now suppose you are a super smart programmer who also rides well and understands throttle control. Let's say you can guess right 96% of the time. How bad is guessing wrong 4% of the time. So 4% of the time the rider gets a surprise which can be kind of nasty in certain situations ---- "by the unpredictable reaction of the motorcycle"

Whiskey throttle of an electric bike is much quicker and more powerful than ICE. I own 3 electric bikes 2 Electric motion and 1 Alta. The word I would use to describe it is VIOLENT.

I've had a few drops recently when climbing super steep hills and not making the climb where I toppled back down and landed with the bike slightly inverted. I went to lift the bike and caught a handful of throttle. It takes a minute to deal with the fact that the bike is still on, "in gear" and yet still very silent. I think a tip over sensor similar to the Surron would be helpful although for most scenarios I'd probably rather have it stay alive and in gear. I think if the phone goes into inverted mode it should trigger a limp mode (forward walking mode) based on how the bike is oriented from a fall.

Overall, I think the bike should allow unlimited throttle response based on the HP setting but if the tip sensor notices the bike Inverted it should probably limit throttle response. The motocross dudes doing table tops might disagree with me but I'm riding single track and mountain climbs so if the bike is inverted there is a problem.

10 hours and 100ish miles of experience on this bike at the moment but I've been riding big and small bikes for 20+ years.

Sounds like the bike light have a rev limiter of some kind based on this post:

But I haven't experienced that yet on the few times I've toppled over and quickly reached for the handlebars. Guess I need to chill out and realize the bike being upside down isn't actually an issue like normal bikes starving of oil or pouring gas out the tank.
