Has anyone done anything to the suspension on the 675 (revalve, replace)? I feel it definitely needs to be changed, it doesn't like any bumps.
I know Ackers has had his 800 done. I imagine it would be similair to the 675.

I am saving my pennies for my 800's to be set up and set correctly... can't wait.:mouthwate

Would I be right in thinking the 675's suspension is non adjustable?

I think you'll need to visit a race or suspension specialist to seek advice, the only option for the stock forks and shock will be to open them up and re spring and valve them to suit, there is a company here in the UK that do it called Maxton so there might be someone local to you who can help?

Yeah non adjustable. I was just wondering if they even worth fiddling with because they are quite budget. I had a street triple r as a loaner bike and while I didn't like the bike near as much, I wanted it's suspension and seat on mine!

when ever you get a bike, new or second hand, put aside some money to get the suspension 'tuned' to you, your riding style, your weight, road/track/touring etc. It may mean adjusting the existing suspension (as provided by the factory) or replacing parts such as rear spring, rear shock, front fork springs, fork oil, ride height, distance through triple clamps forks protrude etc . With the exception of rider training it is the best investment you can do to your bike.

Yeah had plenty of bikes and done this but more chasing info on what people have done if anything and if they have had much gains out of the stock suspension

The obvious question is have you had your bike set up for you with the stock suspension? If this is done then your initial question is relevant. If not then perhaps go down this path first. You should also include your weight as if you are 94 kg then the changes done by someone weighing 65 kgs are irrelevant to you. Also consider rider experience and where they are riding. A bike which feels great for commuting may feel pretty ordinary on the twisties and really bad on the track. All associated with how close to the limits of the suspension you are riding (rider experience) and the ability of another rider to offer comparisons. There are a heap of riders who have performance changes done to their bike and rave about them when in actual fact they can't pick the differences (placebo effect).

Yeah I know what u are saying. Lucky for me im the 'standard' weight (80kg) for most bike suspension. My b3 just has the basic sag/preload set up for me. I suppose my question should be, is it worth spending money on the stock suspension because its budget in nature? Im ringing my suspension guy to see his experience too, but I was wondering if anyone on here had fiddled with there's

Ackers what did you have done? I'm considering MCT once my wallet recovers from the battering it's taken this year (Z4 Coupe, F3 675 and a new flat!)

I had my ZX6-R set up for track by a guy who works out of Brands, and then backed it off a little for the road. The difference was night and day, especially on the track. The track settings killed my wrist, knees, ankles, back.... everything on the road. But I got road settings to back them off to.

Consequently I found the F3 soft and quite imprecise when pushing on. The front dived horribly under braking and the rear picked up. I've gone up a bit in compression both ends and a little in rebound and it definitely feels better. It doesn't run wide as much. I need to get the preload sorted for my weight and style soon.

I do plan a proper set up soon, but funds dictate.

I just had a suspension specialist fiddle with the stock suspension. It's detailed here:

http://www.mvagusta.net/forum/showthread.php?t=72346

I understand the F3 675 is fully adjustable but the B3 675 isn't which I believe is the bike this thread was started about. You can try my settings but be aware mines a Brutale and not an F3 but you can always go back to the stock settings if you don't like it, they are on a separate sheet in the back of the manual.

After much deliberation I've put a deposit on a full mupo kit for my race bike.

It's about time to get rid of the stock stuff.

In the end it was having a local technician attending most race days that clinched it.

I had dissamble the stock fork of my F3, and I discover that it's not working like others at the end stroke: the oil level doesn't play any role on bottom end stroke. The oil level is far more lower thus the air trapped is larger. The only way to hardening the fork is the preload the progressive springs or change for a higher rate.

Will pass on what one of the best supension people in the USA, Dan Kyle at Kyle Racing in Californina has to say about suspension tuning. Untill you have the right springs for your weight and intended purpose to include the proper sag set, you are pissing in the wind. Proper adjustment also means that the preload should be in the middle of the adjustment range thus allowing you to have adjustability in the spring for various conditions. The same philosophy holds true for compression and rebound as far as the settings should be in the middle of the range.

Thats one failing of the stock forks on the B3 800, there is virtually no rebound adjustment and what there is, is at the very end of the range.

The oil visco is tunable> more fluid helps but follows the ambiant temp. The original is 7.5w (=middle)
