Apparently he'll be okay though he broke a few things when he went through the spin cycle.

Quote:
Stoner fell victim to a stuck throttle early in the endurance classic and as a result, crashed hard through the gravel trap. Stoner was immediately helped off the track by the safety crew, but would later reveal on Twitter that he suffered a broken scapula and fractured tibia.

I guess this is the reason they require second/return throttle cable on street bikes.

Mindboggling isn't it that at that level, with the inherent consequences, that stuck throttles are not engineered out.
I find it mind boggling.

In reality it is likely a Ride-by-Wire throttle control. Very few Pro level racebikes in this day & age ride without them. With the software controlling the throttle servo you can program in not only slip factors for Traction Control, but precision auto-blipping with zero latency and exact rev-matching for any rpm/gear combo even when the rear wheel is not even on the ground!

my VFR1200 utilizes RbW, kind of weird and at the same time unnoticeable. Throttle position setting in PC5 is a pain to dial as well.... requires full load/dyno.

So how exactly would you get a "stuck throttle" with ride by wire? Software issue? throttle pot (or whatever they use to sense twist) malfunction? You'd think they'd program in some sort of fail safe, especially at this level, so I've very curious what the issue might have been.

I think no one can answer that. He said/she said situation. I'm sure they can see what % of throttle was during the race ...that's about it. Tbw is very reliable system and used pretty much everywhere now, from airplanes to bikes
