There is no law that says you must have a certificate. You just need to be able to prove that the bike makes less that 33bhp and isn't over the power to weight ratio.

Some Forces will take a bike to a local Dyno for a horsepower to be checked if they suspect it is unrestricted being ridden by a restricted licence holder. 3 were taken to a local Dyno only a few weeks ago, so you pays your money and takes your chances.


They cant accutly do this on the spot, you can request a defered test at a later date on the condition that you dont alter the condition of the bike.

Its just a matter of knowing your rights.

Quite often if I am examining a bike after an accident and the rider is on a restricted licence, I will examine the machine to see if it is restricted and I will ask to see the certificate.


So you'll be stripping the carbs and removing the exhaust to find the restrictors.

What happens if its an offical suzuki restrictor kit since they are restricted by changing the carb internals, they look the same unless you messured them.

On a TT600 they can be restricted by a triumph dealer by using a different map on the ecu. How would you check this without going to a dealer.

As far as the deferred test is concerned an examiner authorised under section (I think the section is still current) 56 is allowed to conduct any roadside examination or have it removed to a suitable place of examination. However I was trying to keep it simple, and very few people are aware of the deferred test which the Police use to their advantage.

As far as me doing an examination is concerned, yes I will and do strip it down to the carbs if needs be (I have done 4 this year) and my evidence is admissable in court. I will also use forensics to substantiate any findings if appropriate and I will work with the manufacturers and dealers if the BHP output is an issue.

So does that mean you don't legally need a recognised 33hp certificate as long as it is actually restricted?

Is it 33bhp at the rear wheel on a dyno, as different dyno's are known to produce varying results? Or is it the manufacturers claimed output at the crank?

Also who else, apart from FI, do recognised restriction kits? FI seem to be very expensive.

Probably not needed for the police, but possibly for the insurence...

None of my insurance companies have specified me to have a 33hp certificate, regardless of having a kit fitted or not. Wink
