How much do you weigh and how do you ride? At 190 geared up (trust me, at 5'9" I'm not happy about that) I find that even the middle settings are very stiff for anything aside from very aggressive riding. I'd be tempted to start at two clicks off full soft and then tighten from there.

Enjoy your trip!

Hi Iron,

I have set mine to the softest setting so far and it's much better than when i got it off the dealer.... i will be returning to the dealer just to get the pre-load on the rear a bit softer like my CBR... that will make the bumpy roads a bit smoother without affecting the front end too much... which i like.

You need to provide details of your weight and height for ppl round here to give u their feedback... there seem to be quite a few here that can do that very well!!!

Now... tell us where your going and what roads u might be using...


PS. I head off on Fri to Coffs Harbour and will be touring around Bellingen and Dorrigo while i am there... never done it on a bike b4 and can't wait... i will try to get to the dealer b4 i head off to adjust my pre-load on the rear!

Thanks I have set everything to between standard and soft - my weight is 77kg and I ride mixed road surfaces.

The tour is postponed a week (due to a unforseen matter) so I will fine tune some more this week and be fine come the weekend.

thanks again.


ps. CT, how was water fall way ?

Iron Chief, my weight is 72kg's. On my 750 Brutale when I toured on it, I put it all to the soft settings, and enjoyed the ride. Have fun!

I don't leave till this Fri Iron Chef.... have done Waterfall way a few times in the car now and cant wait to do it on the Brutale.... ... i will stop and take some photos and then post them.

Not sure on how to send a PM.... but if you are around that area would be cool to catch up... if not... maybe on one of your trips around my home town?!?

Cheers.... Dave

I am glad my trip was postponed - I would not have travelled very far on this bike.

I have been adjusting the suspension towards the softer side and today reached the maximum softness possible - everything set to full counterclockwise at stops and preload now set to minimum front and rear - and still I have a bike that is so firmly sprung that it throws my bum off the seat over minor road imperfections, dips and bumps.

I just went over my local mountain (Mt Glorious-Brisbane) which is considered fairly smooth compared to most other bike roads in this area having alot of hotmix and good surveying and with merely a hour in the saddle I have quite a sore bum and considerable lower back pain.

Feeling pretty low at the moment - dunno how everyone else rides these bikes on Australian roads with such uncompliant suspension - maybe its just me or the seat and the angle it places my tailbone at? My little XB Buell lacked power but be damned if it didnt turn corners just as well whlie offering a smooth ride?

Guess I will have to park it for now and try find new softer springs and have seat padded and recovered as a starting point. Sorry if this post sounds so negative - just disapointed.

(BTW I am 77kg)

Chef, let's see if I can offer some help. First of all, check your sag settings. They can explain a LOT.

My Brutale is also a 750 S. Weight is 190 plus gear. Bike was terrible over any bumps, even small ones. In addition, the front end would compress so much under hard braking I could easily get great amounts of rear wheel lift, even on the street. I was almost convinced I needed to spend large amounts of cash on a slipper clutch, steering damper etc. LOL

IMO, there is nothing you can do with a screwdriver that can make the stock fork work properly. Note, since some riders are perfectly happy with the stock settings, it's likely that not all Brutales are set up the same way from the factory so what works for me... Again, start by checking your sag settings and go from there.

Here's what worked for m-e...

~ Adjusting compression to the softest settings only made front end dive worse under braking without significantly enhancing bump compliance.

~ On checking, it turns out front end sag was excessive. If the front end is too low at rest there is little suspension left for braking and bumps. Increasing preload to the maximum would not get the front end to the recommended height or reduce the excessive dive under braking. Since sag check and front-end dive showed the front springs in my bike were obviously too soft, the problem with bump compliance was due to excessive compression damping.

~ I replaced the front springs with stiffer ones to get the front end height set properly and get rid of the dive under braking.

~ I replaced the 10wt fork oil with 5 wt to reduce compression damping.

~ The lighter oil has completely changed bump compliance. It's like a completely different bike. Marvelous!

~ The heavier springs have eliminated front-end dive and allow the bike to retain the firmness you expect from a sport bike.

~ I no longer need to wear padded bicycle shorts on every ride!

~ It's not perfect but it's a huge improvement. I'd like more rebound damping than I can get with that weight of fork oil so I'll probably get some different internal parts and play with internal valving next.

Good luck. Hope this helps.

Thanks emmvee,

I took it to a bike suspension specialist today and left it there. I will post up what mods I end up getting done but aiming to not spend too much and simply get some compliance in the suspension.
After this I am send the seat to be reshaped, recushioned and retrimmed at specialty bike seat trimmer - am aiming to get the seat reshaped to something like the Corbin style I had on my Speed Triple which shifted the rider to sit in the wider part and eliminated the forward lean angle. Will also post the result up of this.
