B3 Suspension Settings

Have read about others changing the suspension and having it done by "guru's" so perhaps we could start a listing to help others, or confuse?
I set mine up with trial and error over 5 months doing one small change at a time and is set for twisty tight mountain range riding, I am 85kgs ready to ride.
Measurements are listed by same method as per the owners manual.
I found the standard settings too soft for my liking, could get a bit of a wallow up but now is firm and stable and as a bonus it does not
headshake anywhere as much as before - no steering damper fitted.

Front

Preload = 9 turns
Rebound = 0.5 turn
Compression = 2.5 turns

Rear
Preload = 2 turns harder from standard approx 14mm of thread above locknut
Rebound = 1 turn
Compression = 1.5 turns

Pug,

Will check my set-up and post later, one thing I did do which I feel improved the bike was I pulled the front forks up through the yolks (triple trees to you US guys).

The fork top caps measured at 90 degree to the head stock to the top yolk is now 17mm. Certainly feels a lot better to me, if we had a ride height adjuster on the rear that would have been my first option.

I'm 87kgs or 13st 10lb in old money, ready to ride.

Preload front and rear left as standard, the adjustment needed was so small it really wasn't worth it.

Front:
Compression - 1.5 turns out
Rebound - 0.25 turns out

Rear:
Compression - 3 turns out
Rebound - 1.5 turns out

I had this set up by a guru and it has made a world of difference, at first I thought the compression damping must be too firm as the bike was kicking up off the bumps and I thought it wasn't absorbing them but in actual fact it was more a case of the rebound damping that was far too soft resulting in the forks and shock extending far too quickly. It now handles much better and the head shakes have reduced dramatically and I don't have a steering damper either. The guy who set it up for me said the Sachs shock wasn't a bad unit but the forks do not have enough rebound adjustment in them and it was only the last half turn that made any difference, this is due to the budget valves typical of standard suspension so these would benefit from replacement internals.

I would imagine that a guy who set up bikes for Polen and Corser can hook up an MV for a wanna-be-road racer. Well Phil at Ferracci is the guru extraordinaire and he set me up. I'm 182 lbs 5'8".

Haven't had a chance to "test" out his handy work due to the weather.
These are Phil's actual notes....

I think while these settings may be helpful, it's a good idea to note that with budget mass produced standard suspension the exact tolerances during production are probably pretty low so what may work for one set of forks/shock may not be the same on another?

For example Yojeffo's settings, while very similar on the rear the forks are completely different?

I am surprised you dropped the forks through and lowered the bike, that would quicken the steering even more and at higher speeds I would be mindfull of what I already consider a flighty bike.
Once I played with the idea going the other way and push the forks further through the yoke to try and lengthen the wheelbase and slow down the steering a bit.
On another note my TRX 850 really does perform well with the front dropped and the rear lifted.
We all like them set up differently and as noted in the post above these unfortunately are not scientific instruments we are dealing with here, 2 turns on one bike might equal 1 turn on another.
You also would have lost some ground clearance dropping the forks through, I scrape both riders pegs now, however I have replaced the original pegs with a pair of Oberon ones from Design Corse.

Rear setup help

Thanks to Ackers for contributing to this, and others, as the common line was most were happy with rear but not happy with the front.
I was the reverse, front sorted with most having virtually the same setup, but the difference was for me was the back felt odd, I noticed I had my rear comp screwed in and Ackers had his screwed out.
Got me thinking and I tried Ackers setting on the rear and Bingo. much much better, I was taking it in the wrong direction.
Thanks heaps.

No worries, the invoice is in the post
The guy who set it up for me is a master, he just asked me what it was doing and after checking the preload was ok he then he twiddled his screwdriver, bounced the bike up and down a few times and said "there you go, not as good as I'd like it but it'll be like night and day compared to what it was"

Nice settings

Although I like it a bit on the firm side, it was behaving like a bucking bronco in the rear at standard settings. Tried your settings Ackers and found it much improved. Luckily I am around the same weight so your settings were good for me also. Cheers for postings.👍

Do it! Do it now! Don't be a girlie man.
