What year and model are you getting? Regardless, I would not let this concern deter you or keep you awake at nights.
To be honest, I haven't noticed a definite trend regarding which bikes drop valves and which dont. I have seen as many 800s as 675 failures reported here on this forum and more 2014s than 2012/2013s so not sure of the first batch theory regarding failure. Of course that is just a casual observation and not statistical analysis of the failures reported on the forum

My 2012 675 is number 800 off the production line and knock on wood, has been reliable. It is hard to say how many bikes have dropped valves as people come on to the forum after the fact, this means only the failures are posted. In reality, it might not be as bad as it seems.

Regardless, anything broken can be fixed.

I didnt sold it, but always thinking about it while riding just ruined the day. Anyways you'll probably end up with some tiny annoying problems that some brought up on this forum.

But I've seen atleast 15-20 MV's for sale that have above 20K kilometers/ 15K miles.

All I can say is: make sure your fluids are at operating temperature before your start cranking the throttle. But that counts for every motorcycle.

In my discussions with the MV tech rep here in the USA it would seem mostly due to very high rpms.
The 675 has a higher rev limit than the 800 and that is why more 675's have failed....but again, not that many in relation to the numbers produced.

I used to be fast....now I just dream about it.

Good article describing the euro 4. Talks of loss of midrange as suspected.

There have been dropped valves on early 2018 models. A forum member had a dropped valve a few hundred miles in on his 2018 engine. My replacement engine is an early 2018 engine that was held up before leaving factory so MV can throw on the redesigned head...

The dropped valves were mostly a first edition problem with the 675 cc bikes. And 100% of the bikes were not affected. A fair number, but not every one.

"You could tell this was a motor deeply affected by emission sapping as it wheezed and panted to the redline"

This sounds like BS. And the fact that they make it the headline quote is even more BS.

Probably exaggerating to attract readers. But, the article does talk about how it is much quieter and has lost some midrange. I do give credit to MV because complying to euro 4 while still having such an impressive bike is not an easy task. I've seen numerous euro 4 bikes with horrific exhaust cans. Credit to MV in this environment.
