Reduce power ... It's a ridiculous situation .. the bike was perfectly fine to ride in France when I used to come over on holiday but somehow living here now makes the bike too dangerous to ride!!!!!
Removing the speed limiter from the P model

How do you convince the authorities that you have done that (assuming it is possible)? Over here they would go by the spec. book listing its hp, and even if you had Allen Millyard cut off two cylinders the book says it's 126 hp so 126 it is.
Certification from whoever does it and checks by DREAL, French equivalent of the UK's DVSA ....
I could wait another 9 years and then import it with no restrictions or checks as a Vehicle de Collection (Classic) .. doubt I would be able to throw my leg over it by then
So they dyno-test your particular bike to verify it complies with regulations? Not difficult, I used to pull engine from my Porsche every 2-yrs and install bone-stock one I kept on shelf. Just to pass California's draconian CARB test-procedures that had nothing to do with actual emissions! My modified engine was actually cleaner than factory unit, but it won't pass any of visual inspection steps!Certification from whoever does it and checks by DREAL, French equivalent of the UK's DVSA ....

Very easy to reduce power on engine by restricting airflow at intake and/or exhaust. Much simpler than messing with ECU programming and possibly introducing damaging settings. Reduced air-flow results in lower-pressure measured by MAP sensor and ECU looks up lower LOADxRPM point on 3D map to match. This condition was already pre-programmed into ECU!
To introduce this restriction stealthily depends upon how much is inspected. Do they take apart airbox to look? If not, you can just cover up 25-30% of air-filtre with duct-tape on outside/dirty side. Incoming air will keep it pressed to filtre and you'll automatically lose enough power to get under 100bhp limit.
You can also introduce air-flow restriction in exhaust by installing 4x of those DB-killer inserts. These are extremely discreet when installed since it's all internal to muffler. Get one with closed end to force all exhaust to flow through side holes. Can flare outer lip so it's tight press-fit into exhaust for stock look.

Try checking with the shops, which provide 35kW reductions (and certification). They are common in EU for A2 driver’s license. Just an example of such local shop in my country https://www.35kw.lt/ - guys like these should have the knowledge on the subject, what is possible (legal) or not.
