What is the theory behind why the clock would stay where it was pre crash? Surely it should just return to 0?

Exactly that. So in the case of an accident one has to assume the cable (if any) was jammed and could therefore give a completely false reading.

If it’s electronic but with an analog dial a voltage fluctuation or short could also make it read completely wrong.

So basically what it says while stuck cannot be trusted as a valid speed that was even achieved at any point.

If it is controlled by a stepper motor then the dial will remain where it was once power is removed. Old (as in really old) speedo's the mechanism would break (a spring that returns the dial to zero) which would then also leave the dial at precrash speed.
But, all of this assumes that the driven wheels magically had 100% traction prior to the crash and the electronics died before any reduction in speed. In this instance I'd imagine the rear wheel would've lifted at some point with the throttle still open, easily maxing out the speed and then the electronics died
 
I wonder how long it is going to be until someone invents a blackbox for road going vehicles. We live in the era of solid state this and that, so surely making it crash proof won't be difficult, we're not talking aircraft forces after all, so we could possibly get some after action reports for vehicle crashes.

Ecu already has a freeze frame with most of the info in it. Question is whether it's stored when there's a crash

Oh they are basing the speed estimation on what the clocks said post crash.

It’s been proven before I believe that it means nothing and the clocks can be completely wrong.

Not that I doubt speed wasn’t an issue. One doesn’t buy a ZX14 to abide by the speed limit after all.

Eish, my bad.
 
Are motorbike speedos not driving of the gearbox final drive? Last time I checked on my old Presling, speed was taken off the gearbox.

I dropped the bike once and the speed pre-crash was not locked in place

Where the reading takes place is irrelevant. It's about how the speed is transformed into something you understand on the instrument cluster
 
Would a ZX14 not have digital clocks? The ECU should have data logged in its memory. Most cars have data loggers built into the ECU these days.

My dads old C230k was in a random accident, the ECU data files were recalled by Mercedes and it was found to be brake failure that caused the issue, they deduced that by checking the Merc equivalent of VCDS
 
I am having some trouble deciding on a motorbike to commute with as a beginner. My options so far are the small Japanese bikes with ABS (Kawasaki Ninja / Yamaha R3 and so on), BMW G310r, and KTM 390 Duke.

What I can't decide is whether the ABS is absolutely a deal breaker? The Honda CBR 250s are really a great deal second hand at around R25k (not sure if bikes have ABS or not).

Any suggestions / advice would be great!

I am doing my learners later this year.

I hope that this is the right thread!

I was looking earlier this year for a first bike (have since decided on a BMW 650GS as I want to try the offroad thing) and had initially settled on the R3. Out of all those bikes you mentioned, the R3 was voted the best and was widely rated as a great bike for beginners. It's also not a bike that you're going to outgrow in a few months (although this may be a subjective point). Plus, it looks amazing! I say go for it.

How are you finding the 650GS in traffic? And how was learning to ride on the road with it?
