Hi guys, first of all i wanted to congratulate for this great forum!! I have read it for the last couple of years and at last i could buy my first MV, a 2010 brutale 1090rr!!

I started to fiddle with the suspension and the owners manual wasnt so clear on the front suspension preload.. Can someone guide me on how should i set up the compression, rebound and preloads on my bike?

I mainly do fast street/highway driving.. I like o brake hard and turn quick, at least as hard and quick as i can!! Hahaha

Any help would be much apprciated!!! Thanksss

I would be interested if anyone knows the rear spring rate. I have been having bottoming out issues on book settings (222mm ride height, 22mm sag) and I only weigh 176lbs (80kg).
I was surprised that the bike as delivered was set up at 215mm ride height with 15mm of sag. I didn't alter any settings until after 2000kms, so everything should have run in by then.
I have improved it with 222mm ride height and 15mm sag, and then more compression dampening. Turn-in and stability feels great.

I got the attached separate sheet and set it up as it said, but the front preload confused me. Is the standard position fully turned anticlockwise? From here should i make 2 turns clockwise?

Or is it the other way round? Say std position fully turned clockwise and then 2 turns anticlokwise?

I havent touched the rear spring preload. How much should the spring measure? Is that what you revhead are talking about? What does sag mean?

Thanksss

Sag is the distance the bike drops under its own weight (static), or under its own weight and that of the rider (Dynamic).

For some odd reason, MV doesn't use a dynamic sag number. In order to set sag properly, you will need a way to measure from the rear axle to a fixed point on the bike. the knurl and X bikes sell tools for this.

You don't need anything special to set the front sag. Just measure from the top of the axle to a fixed point, for example the bottom of the lower triple clamp.

Hi all 2011 B4 1090RR newb here, The previous owner of my bike was a self confessed larger bloke ( I didn"t see him ), however the suspension setup was not as listed in the owners manual with the bike (Part N. 8000B3377 revisionone 1) as above. 6 turns fork pre-load for a start - no wonder it was head shaking with my 70kg on-board! back to 2 turns waaay more feel and not as angry! The Suspension Setup table in the Owner's Manual I downloaded From Donsy's link
(love your Work Dons) for the 2011 Bikes is quite different (Part N. 8000B3377 revisione 2) particularly for the rear settings;- solo rebound 24 clicks v's 15. My bike is an 04/2011 build does anyone know if the rear damper was actually changed and if so when? CIAO Phil

For those watching the rear spring on the 2011 1090RR is quite light, and running it at the manual specified pre-load (160mm set length) leads to my bike having a rider sag measurement of 47mm!! no wonder the ride is harsh, increasing the pre-load by decreasing the set length to 155 from 160 mm and correcting the ride height has stopped the rear bottoming on our local goat tracks and reduced the bikes tendency to run wide under power out of corners. I would guess that riders of more than 75kg - 80kg will need to change the spring. Ciao Phil
