Speed limiters?

this sort of debate has been flung around the nest for years. there isnt relly a way they can act on this as it is partly breaching our own rights. if i want to go fast, i will, its my responsability if i crash and die an i know that fact when i do it...but we all still do it.
the fact is if they do restrict bikes to say 90mph, the bike industry will go down for big sportsbikes, and a lot of income for importing and exporting for the country would be reduced. but what would we all get then??? a much more fun at lower speeds supermoto. so instead of going fast on a big sports bike....we are all hooning around pulling wheelies....doing silly lean angles, all at 20-50 mph!! that sort of riding is a lot more dangerous than higher speeds!! acceleration is probably the cause of most accidents, not the speed they were doing.

silly silly politicians. give them all a slap!!!

/edit

wont work for us curvy riders tho, but fuel injected bikes and cars would be sooo easy to restrict the speed of

Yes, that's a very bright idea.

However, stick a thin piece of metal down the inside of the pastic housing on the ECU, supply said metal with at least 3.6v, and oops. GPS location has just been lost. Oh dear.

GPS tracking won't limit the speed of any vehicle though, that will take a specific limiter. All you do, is wire in a magic black box. Backward propogating resistor circuit, and the limiter thinks your bike never stays above 70mph. Strangely enough, I have the wiring diagram on this machine for something to do just that.

About the worst that will happen, is they'll GPS track you & fine you for pushing the limit. If you have no GPS record, or your GPS record doesn't match the bike's milage when it comes in for a service or MOT (since MOT's are now computerised), bingo, massive huge fine.

Still, fight that on grounds of human rights & privacy

Vive la revolution!

Ooo err way beyond me!

But that is an awesome avitar Baph - love it

For the techie's on the forum:

The BPR circuit is pretty simple. It sits in parallel with anything that you want to limit (it's sort of how speed limiters work in fact - esp for FI systems).

Basically, you put a resistor just before the BPR, so that the BPR will only ever get a voltage when the entire system voltage exceeds X. The BPR's job is to feed back to a variable resistor in series, way before the entire system. All the BPR has to do, is keep it's own voltage to zero, by influencing the variable resistor.

So, in this example, lets say that 5v means your bike is doing 70mph, and it's limited to 85mph by the limiter. Setup the input to the BPR so that it doesn't have any power unless the system voltage exceeds 5v (you exceed 70mph). As soon as the BPR has power, it changes the variable resistor. When the BPR doesn't have power, the resistor goes back to it's "resting state" & the system acts like the BPR doesn't exist.

In theory, the limiter never thinks you've gone above 70mph. In reality, it might think you've gone to 72mph, but you can't be prosecuted for that Your bike meanwhile, can scream along at 130mph, because the limiter thinks you're doing 72mph constantly. (Naturally if the output to throttle is governed by the limiter, then you'd need to add another couple of wires to compensate for the BPR values and add those on to the limiter output, but even that aint difficult).

Hiding the GPS signal, hell, I'll give my 2yr old my soldering iron to play with your bikes with, I'm sure he could manage it

I don't know how many people are killed in bike accidents. Figures probably are too high.

Smoking kills around 100,000 people a year in the United Kingdom. And yet the Government tinkers with smoking bans, had to be dragged kicking and screaming into bringing one into force in England, and refuses to nobble tobacco companies because they fund the Labour Party.

I think that they need to get a grip on reality.

Maybe they should ban riding motorbikes in Essex on Wednesdays.

"Statistically more motorcyclists are killed on a Wednesday in Essex, than Saturdays and Sundays combined. This is despite the notable increases seen in motorcycle traffic at the weekends."

Limit to what speed? It doesn't say. And motorcycles are polluting? Compared to what? An SUV? The car parks and roads that we need? And limit minimotos? Are anti social minimotos and the average biker the same problem?

This report is a total bag of bullocks and they should just feck off and mind their own business.

Hands up who has ever had an accident on the road at licence losing speeds?
Hands up who has ever had an accident at significantly less (>10mph less) than the posted limit?

I think there'd be far more hands up in the second group.

This story has just been mentioned on the Radio One news. Usually these daft schemes never even make it that far.
