rear hub

Ive had my 1090rr for three weeks now, havent been out on it much due to the weather being crap at the moment. the bike goes and looks great but i have read about problems with the rear hub and i cant get it out of my mind, on a scale of 1 to 10 how worried should i be about it.

1 , just check as per the service manaul ,and keep on riding,its not just going to pop out ,and your rear wheel flys past you.Now if you are paranoid just grab the back wheel with your 2 hands and try moving it side to side,no movement no worries,ride hard .

cheers eddy

You have no worries. The design has been changed to something more robust.
I was paranoid for the first 6 months, checking before and after every ride for filings and wheel play. 31000kms now and no issues at all - regreased every service.
I am still paranoid about chain tension. It must be correct or loose to ensure no force on the hub with the wheel travel. I believe the only recorded failure on a late model bike on the forum might have been due to a tight chain.

MV Rear Hub

Whitey,

The hub collapsed on my 2009 1078 at 5000k. Replaced it with the upgraded hub. Initially paranoid and checked it regularly. Been on some long fast rides lately. Runs a lot cooler than the original. No problems, so on the scale I'd say 1. Regular maintenance checks of course.

Cheers

2010+ models had a different design hub which apparently resolved the issue (I state apparently simply because we haven't heard of any failing but doesn't mean they haven't).

Don't worry about it!

Wink hubs?

given, both my MVs have Mitch hubs......

the 1st generation hubs have 1 needle bearing(which never fails) and a 3810-2RS double row annular contact ball bearing, which is what fails

the 2nd generation "improved" hubs have 2 of the needle bearing that never fail and a 810-2RS single row bearing

so the bearing that controls axial play in the new hub has 1/2 as many of the same size balls in it as the old failure prone bearing

real geniuses designing this stuff

as i recall from the survey......
the lowest mileage failure ~800 mi is a 2nd gen "improved hub"

i posted the torque values on the pinch bolts that distort the rear hub, yes, chain tension can contribute to bearing failure, but compressing a bearing to the point it has no internal clearance is a guaranteed recipe for failure

people assuming that pressure washing is causing the rust/failure need to look at the situation.....

the bearing runs so hot it heats the air in the hub, expelling it, as the hub cools, it draws cool DAMPair back into the hub between the inner race and axle

i have yet to see a 3810-2RS with rust on the outer race......
the hub cools faster than the axle/bearing because of its heat sink, the swing arm
every inner race/axle is rusted

i even drilled a vent hole in my Mitch hubs.....Mitch's engineer didn't agree....my hubs can not thermosiphon moist air, period

Mitch hubs use 2 SEALED bearings and a O-ring between the axle and bearing

the Factory INA bearing have dust covers not seals

a Mitch hub is bulletproof and costs far less than the Factory "updated hub/axle"

take your pick
