I'm guessing you'll be fine.

From my limited experience, the cops wouldn't be an issue, on the street, unless, God forbid, your bike is involved in a serious crash whereby the investigators (who are seriously qualified) do what used to be known as a VEX and discover none standard parts that either could have contributed to the incident or, combined with other parts show a pattern of user attitude etc. These reports used to be shared with UK insurance agents who have an interest, wether it's yours or the opposite party's. Insurers also use their own examiners and it's all about litigation and liability reduction, otherwise known as less, or no pay out.

That's a worse case scenario but that's why you have insurance in the first place....to cover you and 3rd parties in the worst case and is why, more and more these days, you have to tell your insurers of any 'enhancing' mods as they may decide not to cover.

Heavy stuff, I'm sorry....
