There're few ways how such an enhancement can affect the engine.
An excessively rich mixture can result in soot deposits all over the internals of the engine, and an excessively lean mixture can cause excessively high temperatures on the engine.
High temperature within a range by itself is not a cause of short term concern, but temperatures immediately rising in one part of the engine, and the other staying relatively cool, will cause expansion in the hot part of the engine (because metal expands in higher temperature). This may cause minor cracks or other damages. Now, a modern engine is reliable, but physics is physics, ain't no working around it.
An aftermarket exhaust which is of low quality, may burn the exhaust valve of the engine, and disable or interfere with the stock condition electronic sensors on the exhaust.
High flow Air filter upgrades may make the mixture lean, unless the Fi system has a O2 sensor in the exhaust, plus it can compensate to a big extent, which most stock Fi systems don't.
Today's engines are also lot more complicated in terms of electronics, which may also be a center/cause of engine failures.
So, a lot can go wrong. On my Duke 390, all I did was weight reductions. On my Pulsar 208 (it was 180cc when it was stock), I literally modified everything that existed on it, but those times are long gone..
All this reminds me of the statement, Japanese prepare their products so that nothing could go wrong, while Europeans prepare them such that nothing could go wrong... in the course of normal operation.

My advice to Aprilia: If you're seeing stock motorcycles in double digit figures facing problems, then you're the problem, accept it or not. If they're around 5-6, then again there's a high chance.
But it does NOT make you a son of the devil. Life goes on. Things go wrong, even when perfectly planned. You're not the first corporate to have a product problem on their hands. For example, Samsung once kept an exploding phone, The infamous "Galaxy Note 7", in the hands of millions of their customers worldwide and called it back, and in a few months, spotted the problem which was not easily detectable.
Take my advice: call back the bikes, let factory mechanics work on them and spot the problem, issue alternative engine parts, get them factory fitted, and there you go.
In a few years, trust will be retained in the brand, business will go on and people will forget this episode, just like no one remembers Note 7.
But don't compromise on ethics, even if it proves to be expensive. All the Best.
