Hello,
I met someone this week who used to own a 955i before "upgrading".
He now has a Tiger 1050 Sport, it's a beautiful bike, better at the track/corners because of the small front wheel, but... forget offroad. He misses his 955i which was interesting and nice for me!
Anyway he showed me that under the seat [of my model 2001] there is an adjustment screw for the springs, which I should change every time I have a passenger. Recently got helmet etc for my GF and I do notice the bike sinks too much when she climbs on. (She's not heavy btw. :)). Where can I read more about how that works?
Thanks
Hi and welcome!! Did you get an owner's handbook with the bike? It will tell you about it in there.
Hi Chillman...what do you call "not heavy "
Yes you are right Bixxer Bob! :augie
In my handbook (in Swedish) I find two settings, one is "rear rebound damping" and the other "rear spring preload" (the one he showed under the seat). Should I not ever touch the "rear rebound damping"?
According to the book, the "rear spring preload" has five modes. No recommendations though, with or without passengers. It just says "To adjust, turn clockwise here to increase preload".
Is it impossible to turn it too far clockwise or the other way? Do I damage it if I change it frequently?
Which of the five modes is best when alone, and with passenger?
I am currently approx 90kg, down from approx 100kg when I first rode the bike. She is approx 57kg. She's further back, so her weight affects the springs more.
PeteH, heavy would be 100kg. :)
Weights converted for your convenience :icon_study:
My weight now: 90 kg = 200 lbs = 14 stone
Her weight: 57 kg = 130 lbs = 9 stone
Turn the preload to 5 and with a straight bladed screw driver turn the damping to the right (H) I rode with that setting from brand new riding one up and I weigh a lot less than 14 stone :icon_wink: the shock was crap when it was new never mind all these year on but good enough to potter about two up I guess.
But for any decent riding at speed which the 955 will still very easily do then I'd hit the search button there's loads on such.
Chris, pardon my n00bness but what does "preload 5" mean?
I was down at the bike just now, found the tool needed and started experimenting. To my surprise the whole big can moved when I turned with my tool?!
I got 7 clicks turning one way, then 6 clicks the other way, then 5 clicks one way then 7 the other way... Very very confusing. Shouldn't it be the same each and every time?
It seemed to get stiffer when I turned it clockwise. Very stiff when at closewise end position. Correct?
What I'd suggest is go into Google and search motorcycle suspension.
Preload
Damping
compression
Rebound
Because without even the basic Idea you will have no hope of what you are doing.
Setting 5 is max preload
Turning the adjuster at the bottom assuming it hasn't seized from lack of use all the way to H is max damping.
Damping has two parts compression when the shock is going down and rebound when it is coming back up cheap shocks combine both even some aftermarket do to cut cost good quality shocks have separate ajustments so you can control the speed the shock goes down and the then the speed it comes back up.
What you have on your bike as far as suspension goes is called boat anchor quality absolute junk :icon_wink:
To try and understand what you are doing make an adjustment and stand behind the bike hold the rack and press down so the suspension moves and feel the difference assuming your shock isn't knackered.
Thank you, Chris.
Beautiful day, sunny summer feeling. Drove around town for hours alone.
Bike ran beautifully as always but I suppose I left the rear preload one click too high because it definitely was less comfortable than I'm used to, bumpy. On the other hand, possibly that makes it better in some situations (turns?). I'll try another preload setting before next ride.
I also now notice perhaps too much dive when I (front) brake. I'll look into that another week.
I can't understand how you would want it on max preload. Ouch! :)
Apply a little rear brake before front brake, this will help to settle the bike and reduce the initial front dive. This takes some practice but will become natural after a while and result in smoother speed transitions.

Ride the bike a lot faster you'll soon find out :icon_lol:
Thanks both. :)
In the evening today I was going for a ride with the girlfriend. Let's not let these few lovely sunny evenings get wasted! The sun sets at 10pm now here in Sweden so there's time to enjoy even after work.
Anyway, I turned preload clockwise until stop, then counterclockwise one click. Is this what you mean max preload = setting 5? Or it is at the stop?
Easier handling of the bike! For instance in curves. It might of course be just my imagination or improved skills with a passenger but... I'm sure preload also helps. It felt a bit more like when I drive alone.
That was the damping screw you adjusted. The "Preload" adjustment is the large slotted nut on top of the spring.
But if it helped then you know one thing more than you did when you started :thumbsup
This was the one under the seat, a little "metal can" with a nut on it.
