Couldnt find these separately else where so thought I'd put them up while doing a copy for the garage...

Note that the rear axle nut is 90nm and not 120nm as specified in the manual. 120nm may damage the wheel spacers.

Yep, thats right.
The torque value was reduced to 90 nm after the 120 nm value could cause stress and strain to rear wheel bearings.
Having a rear wheel bearing fail on the move is as much fun as a rear tyre blow out, and as bloody dangerous

Thanks for the Info - I didnt realise that change!

120Nm = 88.5 lbs/ft which does not seem too high to me but someone rounded a rear nut off on my Falco in the dim distant past.

I tried looking for updates to the service manual and a rumored full new revision but couldnt find anything newer than on Martin's website???

Cheers

Griff recommends 100 Nm

Aprilia does specify 120Nm but a number of bearing failures has led Griff to recommend 100 Nm.
