have you tried the settings that are in the manual??
I rode mine at the stock settings on the track with no issues and I run on soft settings on the street.

Some are perfectly happy with the stock settings or just a couple clicks of the adjusters but for my riding conditions and style, the stock suspension was worthless no matter how much I tweaked it. Evidentally, Brutale suspensions must vary tremendously between bikes so it's going to be pretty tough to make general recommendations.

I guess the place to start is to ask what's working (or not) on your bike...

What are your current sag settings? Can you get the bike into the recommended range just by adjusting preload settings?

What settings have you changed and what can you not correct with the adjustments you've made?

brutale_racer910,

no stock suspention can match custom done aftermarket stuff...

Brutale is OK stock, but it cannot even begin comparing to my GMD fork and Penske shock on my 02 R6.

I paid $1500 for my suspention and geometry work, and I am sure that it was best 1500 i ever spent.

Just curious... what did you do your stock suspension before you decided it was necessary to go the custom route?

This is a good question. The old saying applies - the best you've ridden is the best you know. In other words, the best you've ridden may be far from the best, it's just the best you know.

Having said that, I'm finding the Marzocchi/Sachs combo on my 910R is damn good. At first I was really disappointed as it was so harsh. I found that the dealer had mis-adjusted the high speed compression on the shock to the point of hydraulic lock on a sharp bump. Several clicks of H/S adjustment dialed that out. A few hundred miles seems to have taken a lot of the harshness out of the fork as well.

I'm all for custom suspension - when required. On our Suzuki racebikes we relied on Jim Lindemann to perform his magic on the low end Showa forks and supply a properly sprung and valved Penske shock. For street use the 910R has very high spec suspension with more than enough adjustability in my estimation.

Have to agree. Both our Brutales were very very harsh to begin with (and I am a fat one!), it took well over 1000 miles to wear in both our 750s suspensions. After a full setup it is superb, one of the best I've used - if still a little harsh for bumpy roads.

I love suspension, always been playing with it. Rebuilt my Hornet front forks 5 times till it was right and setup a few race and trackday bikes now.

My thoughts are no matter how good suspension is, unless its set up it is pure luck if its better or not. Many people get Ohlins etc and live with the best guess it was set to (if your lucky!) - which may or may not be be better than an unsetup standard.

Settting up (for a decent road setup - not trying to get 0.5 secs off a lap ) is not rocket science, there are lots of guides out there that go through the basics, it just takes time and a way of suspending the bike off its suspension.

Always start with standard settings and adjust static sag, your on a hiding to nothing twidling damping without that fundamental setting. Then set the rear ride height to get the bike sitting right. And then start worrying about damping. Make a change and do a 5 mile loop on bumpy & smooth roads not trying to go the fastest youve been but trying to analyse what you dont like about the handling, write it down, have a cup of tea and then try and work out what to fix it with using your chosen guide. The only cost is if you work out you need a different weight spring, the rest is time and effort to learn which repays you a 1000 times over.

Most important thing I learnt is static sag has a range of well defined settings. Too small and you will feel every ripple in a car park tarmac. Too soft and no matter how you play with the damping, it will always feel wallow-y?sp? and if you've over damped it will introduce a whole raft of other problems.

Thats it... 3 in one day...posted out!

Its interesting that eveyone has noticed a definate break in period with the suspension of these bikes. My front fork was as stiff as a rock when I first adjusted the setting to my weight,and it worked very well. As i have put some miles on it, it seems to be diving again under hard braking....another click on the preload?

I definately noticed a break in of the suspension. I remember the first day I got my bike, it was ROCK hard and did not sag at all with the stock settings. Now after 1200 miles I can definately feel it sag when I get on. I haven't played yet with the settings as it is working pretty good out of the box. Rear probaby could use a touch more compression/rebound over stock to stablize it fast sweepers.

No harm in trying it. If you really want to get a better handle on it, compare the free sag/loaded sag front and rear to the original measurements. That's your best indicator of whether the change you've noticed is due to a decrease in fork stiction or it's due to springs sacking out. Two different causes, two different fixes, but sometimes the fixes do "overlap".

I followed the manual and had it on the stiffest setting...confidance inspiring...and nice....gives the bike an even more "race" feel.

Switched it to the softest setting according to the manual, and it's LEAPS AND BOUNDS (for the street atleast) more stable as it soaks up all the road imperfections even better. You feels EASILY TWICE as planted...

I say softest setting for street...and it's still worlds stiffer than any jap bike I've sat on...

Anyone know where to get aftermarket fork springs for the Marzocchi's? My suspension guy told me to find a 0.90. I'm a lightweight.

I usually start with the stock settings until the suspension breaks in. I usually give it about a 1,000 miles. Then I go for a ride on a road that I'm familiar with and make sure there are some bumps in it. I usually take whatever tools I need on the road and start softening from there. Italian bikes usually come set up too hard from the factory. I guess they have racetrack smooth roads there! For every two clicks of damping, I usually do one of rebound front and rear. Usually gets me in the ballpark.
I also raised the rear ride height about 4mm to get more bite out of the front end because I was using it for track days. The front end pushed a little while turning in to fast corners.

Hey there all,

Just did a new post to the list but I thought I would chime in and say I have messed with everything from damping to rear ride height (WITH parental supervision) and cannot get either end of my 910S to inspire confidence and so am told to get softer springs (w/gear I weigh about 175# or 79.5kilos).

But Race Tech girl says she has NO idear how to help me. She has no idea what springs ANY MV Agusta takes... Can't get there from here!

So any advice would be a fine, fine thing indeed!

Ride Well,

Gabriel
