[MAR5H7]

I was just wondering, if your not doin a tonne n a half, how do they know if the bikes restricted or not????

I'm genuinely just curious[/quote]

They'd have to put it on a dyno.

the police cant
They need an engineer to check
police are not qualified to give that evidence

Few ways. My friend got caught out. He had a zx6r ninja. Should've been restricted, but the copper pulled him because of a loud pipe, asked to rev it, and it revved up too freely and easily. So they confiscated it, dyno'd it. And it wasn't restricted. End result= Lost licence and a years ban.

Got my bike restricted after I heard that.

If they catch you going over 30mph on a 50cc aged < 17, or over 80mph on a 125 on L plates, or over 100mph on a <25kw licence, then logic says you're riding an unrestricted bike and if they have any sense they'll seize the bike and get it tested. In reality this almost never happens.
I rode a 2 stroke 250 and a VFR400 both unrestricted on a restricted licence for 2 years. Got plenty of police attention but never had restriction mentioned once. A few times they asked how big the engine was, but they either assumed it was restricted or that i could ride a bike of that size on a restricted licence. You might not get away with that on a sports 600

[MAR5H7]

Fair enough
I have a zxr 400 n an SRAD 600
About to start riding the 400 soon
Was just wondering as I don't really wana put them in, won't b riding over a tonne, just cab to put them in but if it's that risky, prob worth while
Dnt fancy a ban n losing my licence after just getting it

What is the point of risking your license anyway yes the police might never catch you during the two years. But if they do you have just wasted your license fee stupid mistake to make.

If you're license dictates that your bike should be restricted then why not have it restricted? I would imagine your insurance would be invalid as the bike 'should' have restriction and it doesn't.

As said, not worth the risk.

i got pulled over last year accelerating off from a slip road, bloke pulled me when i was doing about 90... all the normal questions at the side of the road, got out my license and it was an old one without the bike entitlement on it! cue more questions,

he asked if it was restricted, i obs said yes (its a gpz500, not restricted ) he gave me a knowing nod... said it was fairly nippy for 33bhp!

eventually he just let me go - copper was a biker himself that had just dropped the bike off to get fixed, clear road, dry day etc.

needless to say i'm remembering to check my mirrors before i go for it

best advice if youre not bothering to restrict - don't give them anyone any reason to pull you over!

Hi

Didn't know that R6 or Daytona speedos were that far out.

All the best

115mph on 33bhp? Was the bike falling out of the sky at the time?

33bhp is around 30% of an r6's unrestricted power, top speed of an r6 is somewhere between 150-160mph.

OK, it's past Wine O'clock, so I'm not going to cite the statutes, but here's the procedure.

A copper doesn't need any reason to pull you over.

You technically enjoy a right to defer any roadside test unless the vehicle is obviously not roadworthy.

However, the copper only needs a "reasonable belief" that you're riding unlicensed in order to seize the vehicle. In practice, refusing to co-operate can and will be construed as "reason" to believe that you're unlicensed for that vehicle.

Once seized, there's no statutory process for hurrying them up (unless there's something in PACE, someone who's not wined up might find it), but do start hassling them ASAP.

The bike doesn't have to be "restricted", it just can't be making more than 25kW "net power output". You can achieve that with restriction, or neglect, it's up to the prosecution to prove their case, not for you to prove your innocence.

"net power output" probably means power at the crank, and a dyno is only going to produce an estimate. However, if you're over that at the rear wheel, you're boned. In practice, you may (but don't bet on it) have a 10% margin in the estimated figure.

As always, if prosecuted then you can plead not guilty, and then change your plea at the courtroom door if the prosecution actually turns up with their homework.

In practice, the safest route is to pass A2, don't ride anything for 2 years, then buy your S1000RR. Nice one, Brussels.

I don't know why people risk it. You are basically riding illegally and if you were to crash and it was your fault, your fecked. You would be classed as riding without a license.

Staying at 33bhp did me no harm at all, it was fine, the bike topped out at about 92mph, which is too fast for the road anyway. It got there fairly quickly too.

Being at 33bhp also taught me to really maximise every gear change and to ride well to get everything out of the bike. I loved thrashing my ER5 over the tops. It's far too easy now with 100bhp, there's no skill in it at all.

I think they should do something similar with cars as well tbh.

just stick my snout it here my blue hornet @ 33bhp with a race can pulled a indicated 120mph .... on hornet owners day out took a long time after 110 but it got there... probaly a true 105-110

also my zxr400 @ 33bhp would hit the 180kmph limiter

Hi

33hp at the back wheel is enough for an aerodynamic bike to hit 110mph.

33hp at the crank will be about 30hp at the back wheel, and most bikes are not that aerodynamic. 30hp at the back wheel with the aerodynamics of a 600 Bandit is enough for a gnats over 100.

All the best

when i say 33bhp i mena it had a set of restrictos in it .
the zxr400 had a full micron system , hornet had a race can

hornet would pull 95 in 3rd on the limiter and about 110 in 4th then the rest was slowwwwww progress down a hill lol

haha what i was thinking tbh ham but when i took the 33bhp out of the hornet and have it proper beans liek i use to omfg ! hahaha had it in the sky for 3-400 yds almost looped in into 2nd lmao .

the zxr400 indicated 130 in 33bhp not that i think it was 33bhp .... as it had the full race pipe + k&n + jetted carb by previous owner .

Performance Bikes did a group test of 2-stroke 125s many years ago, derestricting them the most powerful nudged 30 odd hp and of course these bikes weighed little more than 110-120kg.
Their top speeds were in the region of 96 to 101mph.
Can't really see how something heavier with a badly strangled engine is going to do more than that!
I mean a cb500 makes possibly 50 odd hp at the rear wheel (?) and does about 115mph flat out which is in line with most of the 500cc twins.
