Restriction legality.

[Paulington]

Hey there guys,

I am just after some clarification from some people that may be a bit more knowledgable than I.

To replace the SV the father was thinking of picking up a K8 GSXR600 for both of us to use along with the KLX300.

One of the benefits of this is the S-DMS so we have the A, B and C driving modes.

I was wondering as I am 33bhp if we had the ECU maps programmed to:

A: Full power.
B: Rain.
C: 33bhp.

Would this be legal? Of course when I am riding it it will always be on C as the police are on my back about restrictions since my crash last October but he doesn't particularly want to ride about on a restricted bike.

Just wondering if anyone knows the legality of this? I am unsure if the law is the bike doesn't put out more than 33bhp in current configuration or is not capable of putting out more than 33bhp at all.

Cheers for the help.

AFAIK you can ride a 'Busa as long as it's restricted to 33bhp. I suppose if you could prove that it's in 33bhp 'mode' if/when you get pulled you'd be fine.

The law states the bike has to have a power output of <= 25kw.

To me that means at all times. Switches are illegal, and you'd probably get in even more brown stuff if found out.

Would you be able to change the output whilst you were riding the bike?

It's a very intresting point. Maybe go your local chop shop and ask what they think?

If you wanted you could do it and if he gets took to court it would be up to the judge to decide and then set a precedent.

The way I see it is that if the switch for changing modes is on the bars then I don't think that would be legal. If the switch for changing modes is hidden away under the seat meaning that you can't change modes whilst riding, then that goes some way to show that you couldn't be using the full power mode so you'd be legit.

If the switch is accessible when riding then that means the bike can make more than 25kw.

[Paulington]

See this is the issue.

No-one knows, not even the Police if this is legal.

As I presumed it was innocent until proven guilty, they'd have to prove I was on A or B as far as I know they retain the onus of proof in this situation.

However, if it's something like the bike can not put out in total any more than 33bhp, then it's illegal.

Like I said, looking for clarification on an interesting point!

Hi

Suspect as it can be changed on the fly it is no different to trying to claim that you are not opening the throttle enough to exceed 33hp.

All the best

Is anyone able to find the actual legislation that rules this?

I have been looking at the Statute Law database for hours and can't find a trace.

Hi

The legislation is here:-

https://www.opsi.gov.uk/si/si1999/uksi_19992864_en.pdf

It just says "net power output".

Afraid I do not see how it would be legal to use the switch. No different to just not opening the throttle enough to go over 25kW.

All the best

I disagree with everyone else, as im sure ive heard of a bike before programmed for a 33bhp map, injection of course. and that was legal...

I dont think you'd have a issue if it could remember which mode it was, even when crashed and if the switch was well enough hidden that a crash assessor wouldnt play with it..?

Proper paperwork is gonna do bugger all.

And crashes can happen for whatever reason. There's other people who've had more in less time for stupider reasons.


Still no need to be a dick about it.

Hey guys,

There is the PCV, which I guess I could mount under the seat in a place where it's impossible to change 'on the fly' as in the bike has to be stopped to do so, still thinks this conflicts with the law though.

As I said, I guess I'll just have to make my Dad put up with it! .
