motorbike and engine number

[skyebiker]

hey guys so i recently bought a monkey bike which is registerd as a 50cc but it has a 110cc engine fitted i phoned the police up to have them make sure the engine is not a stolen engine so im all happy with that.

im curious to ask is it okay to have a non matching number on a bike ? or would the police take the bike off me even though it would be insured, taxed, moted, with L plates on even though i have a full car license.

i just don't wanna insure it only to have it taken off me for non matching engine number

you can have whatever engine number you want its the vin on the frame that matters

thanks for that , would it be wise to go to the police and get them to check the engine number on the bike to make sure its not stolen, i know the bike and vin is fine as i HPI it but the engine number that could worry me

Hi

Engine number should match the one on the log book. And the log book should list the correct engine capacity (and you need the insurance and licence for that capacity). Otherwise it is a bit naughty

All the best

thank you for that im doing my cbt on sat i just would rather everything be legal as riding a monkey bike will draw a ton of attention , i have had a car license for 5 years but i don't mind putting L plates on it

[skyebiker]

would i still be able to ride the bike while the paper work is going though or is it to risky ?

Not that I'd incite anyone to break the regimes dictats but

Declaring the engine change is likely to result in many £'s increase on insurance, I'd bet to the point you may as well just get a 125.

The odds of being caught if not declared are probably not so great. If you don't act the twat you are unlikely to get stopped, if you get stopped you would be super unlucky to get a plod that can tell the difference between a Chinese 50 and 110 from sight.

I wouldn't declare it if it was me.

[skyebiker]

yea wr6133 but if i get a plod who is clued up won't they seize the bike for frauding insurance

If its registered as a 50cc motorcycle, then the 110 engine can be declared as a simple capacity change.

However, if its registered as a 50cc 'Moped', then then, to do it 'legal', you would have to get it re-registered, under new 'taxation class' of motorcycle.

Moped, by legal defanition of the tax class, is less than 50cc and restricted to no more than 30mph.... a 'restriction' that is also now applied to licence entitlement, as well as the C&U regs...

Go more than 30mph, and pretty obvious that what you are riding CAN'T be a 'Moped', there-fore, irrespective of what paperwork you may have, t is NOT the vehicle described on the registration.. insurance then obtained against that registration, is NOT for the vehicle you are riding, at more than 30mph, and the list of potential crimes that they can use to 'seize' the vehicle, starts with it being other than described by the registration, goes through being uninsured, and untaxed, through to their Judge-Dread 'Section 59' powers, that on their 'suspicion' you have committed a crime, they can circumvent actually proving them, and issue a Section 59 Notice instead for 'antisocial use of a motor-vehicle'... on the catch-all that 'anti-social' is almost anything they don't approve of... get two Section 59's and bike gets seized, and you get fined for the privileged, and points on your licence...

Reg-Registering a moped as a motorcycle, is possible; but can be expensive; regs require the vehicle to be inspected against the higher C&U standards for a motorcycle, more a 'self built' motorcycle, not merely the paper-work shuffling bureaucracy of 'self registering' a type approved 'standard' Chinky bike like a Lexmoto or CG Copy.

C&U Regs for mopeds have numerous exceptions and exemptions to the general regulations for a motorcycle; for example, a moped does not have to comply with the minimum tyre tread depth, or have speed and load rating markings on the tyres; 'motorcycles' do.. so it is entirely likely that a standard production moped, could 'fail' C&U inspection as a 'motorcycle'.

Re-Registration as a 'self-built-special' is also expensive; and in all likelihood, more so than merely buyng a brand new chinky-copy DAX monkey-bike, registered as a 110cc motorcycle.

Your call.... how much is it worth to you? How likely do you think it is you'll get caught?

Remember, those section 59 powers exist, and can be applied no matter what, and folk have been given Sec 59's for loud exhausts or doing wheelies, on other-wise utterly un-contentious motorcycles....

Best 'parlance' I could come up with to describe what is variously NOT defined explicitly in law, other than by by inference, omission and exception, and only really seems to be given status on the log book where its distinctly called a 'Moped' as opposed to a 'Motorcycle'.. and purpose of the log-book.... is to know who to send the tax bill to..

The thing is, a "class" of "moped" raises more questions than it answers.

There are some differences about lighting and tread depth in the MOT, but those are defined in terms of engine capacity and/or speed and/or year of manufacture, for which a simple yes/no definition of "moped" isn't sufficient.

And on licensing, "moped" might or might not - depending on when it was first registered - imply that it's OK to ride on "P" entitlement, but not necessarily on "AM", and god knows about grandfathered in entitlement from old "B" passes.

OP, have you bought a 125 yet?
