You won't have a licence for a 125 with a 250 engine either, so just buy yourself a 600 and be done with it.

Do you have ANY licence?
But hey, Criminal Genius...where you going to get a CBR250 engine from? If you want t ring a 250 as a Learner-Illegal.. and ride with no licence, no insurance, no MOT, no tax, on a bike other than described on the log-book... why go to all the faff of finding 250 engne and tryig to fit it into 125 bke; why not just unbolt the Reg-No from your 125 and bolt that to the 250, you wont have to take engine out of?
Same ultimate conclusion; 250cc bike, that wont 'ping' ANPR.. but get you rght royally fucked if you do get pulled and chcked over...
For what?
CBR125 delivers what 14bhp and might achieve 70mph.
CBR250 delivers what, 22bhp and might just about reach 90mph?
I mean this doesn't even get you into de-restricted NSR125 terratory, does it?
And you want to do a shit load of spanner twiddling, to make such a not really a 125 but still 125 slow bike, and are prepared to risk a rap-sheet longer than your arm, fines bigger than the national budget deficit, and a licence you dont have....
Go for it.. let Darwinism run its course!

Really? What sort?
Mines pink; and has valid from dates next to the entitlements that were some-time late last century.
For no effort with spanners or welder, I could, for less money than it would take to buy a half way to the scrap-heap CBR125, "I wanna be a Fire-Place" 4-stroke commuter in a play-suit; buy a genuine Fire-Blade or Black-Bird or any of a hundred other genuinely high performance, genuine sports-bikes, and ride any of them quite legally, or even seriously illegally.. with near triple national limit top speeds!
Ooooh! Hang on been there, done that, got the SP30's on that aged pink licence to show for it!
NOW... you want to stuff a CBR250 motor into a CBR125 frame..... 'cos well... lets look at the criminal genius of the scheme shall we?
Lots of work, to make your bike less valuable and less reliable; to defraud tax man, invalidate the registration, and your insurance; and gawd knows how many other potential 'crimes'.. all to achieve what?
A bike that is STILL 125 'slow'; no faster than any of the older un-restricted two-strokes, that at least have frames designed for their full power but still sub triple digit top speed performance, rather than an over-stressed over dressed cost-cutting commuter bike.... That you reckon you will be able to slide under the radar.. by riding it 'carefully' 
Yeah.... so you rather defy any gain you achieve by not exploiting it, to remain unobserved.... that's likely isn't it! OR you exploit it... and risk getting tugged... and having book chucked at you, for everything and anything, from not having licence entitlement through riding bike other than described on V5, hence not insured, and having the thing seized and crushed before they decide how much to fine you for the next decade, and how big a ban to give you...
For what? Maybe an extra 5-10mph more top end on a good day.. without having to go to the effort of what? Doing oooh, a couple of hours of tests that cost barely £150.. so ALL they can chuck at you is an SP30.
Hardly the fiendish criminal genius of a Professor Moriarty is it?
But, as ever; all the evidence of the criminal genius at work; an aspirational detachment bordering on the delusional; absolute conviction "I WONT get caught", combined with similar conviction that the reward is completely and utterly worth the risks that delusion perversely denies are likely to result in a negative out-come; in the face of an ego that wishes to inflate those risks, for the 'rebel-cudos' of beating the system; Combined with a laziness, that wants it all, here and now, right away, for minimum effort.....
To the point that criminal genius has to reveal the criminal master-plan on a public forum, to even find out how to start!!!
[asside] Hey, Mr Police-Man... how's that pop-corn? Salted or Sugared?
But hey; you say you have bike, you have engine... go grab a tape measure and start from the chain run, measuring up the mounting point spacing and clearances around the engine.. most motors can be stuffed into most frames with a little plate to make brackets, a hack-saw, drill and welder...
https://i46.photobucket.com/albums/f133/blade625/GSXR-mini.jpg
Its your daft idea, run with it.... keep us updated with progress; your audience is agog, and will be progressing from the popcorn to the donuts duly, I am sure!

OP
I think you'll find most of us here have a licence, and the majority of those have full A category.
This is because we've done the training, paid our way and done things properly and legally.
Plonkers flying around on dodgy illegal bikes that are either stolen, uninsured, falsely represented
on the V5 or tampered with give all of us who have done things the right way a bad name. And we're already
seen in a negative light by the majority. Bikes are expensive, training is expensive, kit is expensive, insurance is
expensive, tyres are expensive, parts are expensive, mechanics are expensive. Figured it out yet?

The modern CBR250 is a single. 23.7hp @ 9900 revs, such racebike.
I'm fairly sure it's not the same frame as the 125 though, so it makes no more sense to try shoehorning a Honda lump in than anything else.
Anyway, OP - who is totally real and not at all trite - "has" the bike and the engine in his possession, so is in a better position to say whether it'll fit than fakehate swivel-chair internets experts.

2012 CBR is change-over year between the early Sega-Super-Hang-on styled one, and the face-lift YZF-R125 rivaling model, I think.
Both have 4-valve LC singles, in a pressed steel frame.
CBR250's are another matter! '86-96 4-cylinder 'Baby-Blade' with then Japan Market licence friendly 45bhp, that revved to an astounding 22ooo rpm, is still an astounding bit of kit. I'd buy one 'just' to rev up in the garage doorway, I think!
Y2K on CBR250's were a rather lack-luster 4v water-cooled single, using the CRF 250 dirt-bike engine; an enormous cost-cutting job, they didn't simply shoe horn the CRF lump into the 125 chassis; seems it got its own unique welded tube & plate frame; and less power even than the old 250N lardy-dream, let alone the old air-cooled 4v single 250RS!
CBR250RR 'twin' is supposed to be launched this year; and suggestion is that it may have as much as 38bhp! Which is slightly more inspiring than the old Super-Dreams, I suppose... but I wonder whether by the time they have made it emission friendly how many of them will get to the back wheel?
Dirt-Bike motors into a 125 road frame? NOW you are talking.... but I would't start with a CBR125, I don't think!
350YPVS Mito? Huquavarna- Aprillia 500? Maybe an NSR/CR250? These could all be rather 'useful'.. but have been done before...
Sort of puts Moriati, there's plan in perspective; though; So much work for so little gain, and so much risk!
I could slap an old air-cooled CB 'two-fifty' engine into a thirty year old CB125 Super-Dream, in about twenty minutes, without having to make a bracket, or swap a bolt; most vexing bit making a piggy-back connector to fire both CDi's off one sensor, but I already have one of them, for 'some' curious reason lol! Still be four-stroke lightweight 'slow' though. More 'fun' ragging the arse off the 125 lump trying not to brake for corners!
