Which is strange when you think about it, I mean isn't that what one of the benefits of V-twins/4's was supposed to be, the opposing cylinder banks would cancel out some of the rotational forces, as well as the engine/bike being able to be more svelt compared to 4 cylinders across.
I think it has more to do with the longer wheelbase but I'm not an engineer so I have no real knowledge of what's at stake. Aprilia was able to make a fairly compact V4 by narrowing the V but could never get it to work right. They threw in the towel and built a 90˚ V4 like Honda and Ducati. Their pace is near the pointy end all of a sudden and that's with a brand new bike. So who knows.
Quattro won the trackday. Combined results, El Janitor didn't set the world on fire.

I wonder how it sucks the rear down like that, as electronic motors etc are illegal... I could see if it was a mechanical catch or something and he bounced on it, but it looks like the bike just lowers itself.
Weird. Almost as if there was some invisible force acting on the motorcycle to draw it closer to the ground.
There's a knurled knob on the left side infill panel to engage it. Maybe it's some kind of hydraulic reservoir that transfers fluid?
https://www.google.com/amp/s/www.cr...ati-holeshot-device-caught-camera-updated?amp I would imagine whatever yamaha is doing is similar
Maverick said he did not go for a fast lap on soft tires in this test but instead focussed on spinning laps and gathering data
At the rate it drops the rear and with how smooth it is I gotta think it’s hydraulic. The knob is probably for easy adjustment with gloves on the fly.
You got me... they must just be using springs that are easily overcome by the force of gravity and I totally missed it... Thank you for your valuable contribution and helping bring greater understanding to the masses.
