You got me thinking guys.
Next week i will have the 24k kms service done...although i have 21k.
As you might remember the MV AGUSTA dealership in Greece has closed down and the service will be done at a friend mechanic who only does SS bikes.
As i have no idea...can you plz tell me , do i need to replace the rear hub or just check it for signs of wear?

My bike is a F4 750S evo3.

Thank you all

Rear hub bearings to be cleaned, inspected and greased or renewed at every 7500 mile service (12000 Km).

Proper chain tension (not too tight, please), and fastener torque are essential to bearing life. Pressure washing will also shorten life by driving water into bearings and washing grease out.

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

If the hub is in good condition it will push out easily I had to bash mine with a hammer!

Will check this new bike every 12000kms myself - don't trust the workshops anymore!

I'm pleased that this fault was found by your service agents, to think what might have happened if it had seized at high speed or around a bend is unimaginable. As this seems to be a common fault I consider this to be a very serious manufacturing fault putting peoples lives at risk.

The bike only has a miserly 7500 miles under it's wheels, it appears to be well looked after and dealer serviced. MV should cough up and pay for replacement even though it's well passed it's warranty.

Is this part fit for purpose? As it's not an isolated occurrence I'm not sure that it is.

What would happen if Ford produced a part on their cars which would endanger lives? Would they ignore the problem, I don't think so, vehicles would be recalled and modified parts fitted. What will it take? Somebody to loose their life?

That's my two penneth worth.

Hi Gazz

You are right about 'fit for purpose' it's clearly not. To have the hub of a high performance sports bike incorporate three different types of bearings and have some sealed and unsealed is a recipe for disaster. Clearly dangerous and quite a sobering thought when i think of what could have happened!! The bike was well looked after, but was serviced by a dealership in ipswich (not mv) prior to my purchase. I know what mv would say if i tried to claim on the spindle.

But complete failure at 7500 miles is a joke.

I just wonder if the hub has ever been modified for the later bikes or whether the same hub is still used?

As for putting pressure on mv, i believe it would have to be a collective approach by all of us who have been placed in danger by what otherwise is a fantastic bike.

thanks

Well said sir. I echo your sentiment that the rear hub fusing into something unrecognizable with only so few miles is ridiculous indeed.

I would also like to know if the hub has been modified in any way. All I do know is on my bike I switched from the stock hub to the magnesium ORO hub through my MV dealership when the bike had around 3k miles. I will still be of course making it a point to get the hub checked out at every service.

I hope MV have not repeated the same mistakes (overheating, hub) on their next gen of bikes.

That sounds like a good idea.

wow that's fark. How come the spindle split in two different places, could it be that the pervious owner or service person over tighten the spindle? If the hub failed wouldn't the bearing(s) discinigrate well before the spindle?

Also how come the 55mm nut is blacken and burnt in colour? Did someone use a blow torch to release the nut?

Slow is smooth and smooth is fast!!
