It's the same back to at least 2014 model that I can be arsed to google for
The only way they would be able to check is to rip the top end off and measure, so I would say your safe.

I assume they just want to know if your engine has been modified with an over sized piston etc.

Think it's for the random noise test meter
Sharpie the numbers on the engine somewhere just in case, and forget about it

Its the same Lee: 88mm bore, 57.5 stroke.
As shocker said, it will be on the barrel somewhere, get a marker pen & just highlight the numbers, I heard it's to do with noise level & stuff with pricks who argue their fmf/akropovic ... etc ... etc ... are noise legall for FIM approved race, somehow by bore & stroke they can work out the legal noise limit, dunno ??

Get a sharpie and scribble it on the cylinder so it's in view of scrutineer and noise tester
