Default Rear Bearing Problems - Solved for the F3?

Hello All,
Now that the new F3's are being delievered and people have the chance to put some miles on em, can anyone comment on whether the rear bearing problem that the F4 suffered from is no longer present with the F3?

It's one of the major factors weighing on my next bike purchase decision. Any info would be appreciated.

Cheers

Hi,
Due the construction , the stress on the bearing oblige a change every 36000km, with a regrease at every 12000km , like the front whell bearings(described in the maintenance manual).The look has this price, monoarm is not so strong, it helps the exhaust positionning .
Fortunately, the bike is lighter , the torque lower too.
Cheers

Right, the manufactured specified maintenance isn't an issue, that's accepted.
My issue is that the bearings start to go well before the change interval and can lead to a catastrophic failure/crash (many threads on this in the F4 forums).

Mono-arm is fine, but I'd like to know if they addressed the bearing fault.

I have no problem with my 20000 mile 98 Brutale.

There are those who have had problems and those who have not. This will start yet another heated discussion, but the internet is where a few people convince many people a problem exists (I am speaking in generalities here, nog just MV hubs) . I contend there are a great many more MV owners who have not experienced hub bearing problems than those that have.
I would not let that concern deter me from buying an F3..

Those old hubs on the old F4's have been replaced as far back as 2010 mate.

You missed the point ED, you don't use the same hub as the F3 or even the Y10+ bikes.

But yes, you are probably right in your statement.

I've got a F800S too , my wife's bike , I have to change the rear bearing too after only 22000km, because most of the time we rode both on the bike (more confort too), but it 's also bad engineered although the bearing is a double balls angular contact(special one=the better against lateral forces))
It's a common change for MV, but we will see what happen with the new 1199 duc, the maxi torque is not helping to prevent fast wearing and there is no need a mono arm with the new lower based exhaust; the D16 has a double arm, it's not by chance, over 150HP, the stress is enormous on the mono arm bearings....

Just food for thought...all cars and trucks and airplanes and ... use mono arms and bearings. Someone please tell me the load on an F4 rear is larger than the load on, say, a C130 transport at landing....

What's(are) the size of the bearing(s)? Are the arms aluminium ones? Not sure...Dis you scan the hub temperature after a strong ride??
Divide power by bearing surface etc etc
Mecanic is not magic, is logic.
