Just curious if anyone could give some information on lowering the suspension, and / or general information on any type of mods on the suspension of an 1125R
Thanks

general idea is that slamming a bike changes the suspension geometry and handling characteristics, usually adversely...

but to better answer your question, for what reason are you wanting to lower the suspension?

-aesthetics?
-seat height?
-ergonomics/comfort?
-drag racing?
-other?

Jason:
This has been discussed a number of times, like Matt asked why?

If it for anything but drag racing, the suggestion will be: 1) remove foam from seat 2) get thicker soles on your shoes.

Beyond that use the search function if you want any other answers. It has been discussed 2-3 times at length. I'll save you a little time, look here: http://www.badweatherbikers.com/buell/messages/290 431/349663.html

I'm short but not super short, I'm 5'7" and I tip toe when I come to a light, I would just like it a little lower, I have no problems when riding it of course just when i come to a stop I would like to be a little more flat footed.....

Ok that says don't modify the suspension, I know the rear shock is adjustable, does it just adjust the rigidity or would adjusting that help? It's not that huge of a deal, I can get both feet down just not as comfortable at a stop, guess I'll just have to keep it rolling haha

depending on your weght, you might want to check your sag. you might be enough of a supension drop to feel a little more comfortable by setting up your sag. do it my the measurment and numbers, not by the book. if your supension is too stiff for your weight, you will be riding too high in your suspensions travel. just a thought

lol. you could also benifit from checking your sag. lets say you weigh in at 150 or so. at the "correct by book" pre-load, you may have little to no sag. adjust pre-load or respring for your weight to regain the 30-32mm sag would benifit both ridability/performace and ride heigth

Jason you are heading down the right road. I usually go to max sag if I need a little lower height and adjust compression/ rebound to make it feel better. Just remember small changes in dampening adjustment make BIG difference in feel and how your ride handles.

have a helper or two with you. raise rear of bike from ground and measure from a fixed point on rear swing arm to fixed point on bike. postion bike in upright riding position with the gear that you normally wear/carry. have assistant press down on rear of bike and slowly allow to raise. now measure same two pints and recored. have assisstant lift(about an inch or two from rest position) rear of bike and allow to slowly lower and record. add last two values together and divide by 2. subtract new value from the orignal value(wheel off gound). this number represents your sag. most things i read show a sag goal of about 30-32 for the street. now repeat same process for front. if you are weighing it at 120 lbs, odds are real good your sag is too low even at lowest pre-load. if that is the case, you should look into a lighter set of springs for you weight. hope this helps some

hey LittleBQ,

What did you do your seat. Really like the back support. Did you modify or from upholstery people?

I'm in the process of getting the suspensions shortened and the springs replaced for my weight and height. I'll post the results in a few weeks when I get the bike back.

I don't think we need to ask "why" when folks ask us for advice; let's just tell 'em what works for us and be done with it, hey?

Little, I'm impressed with your seat; where were you when mine was being called a 'toy' because it was so petite? ; )

For myself, I have the suspension set to the range that has the rear shocker set at #4, even though I'm substantially heavier (90 kg in full dress) than the manual indicates it for. The bike handled very well on the Phillip Island racetrack when at the CSS there.

Also, for better straight line control, I have the forks dropped until the tops are level with the upper triple clamp.

i asked 'why' to try to better answer his question.
if he wants to have a lower riding position, maybe some clipons would be a better/easier option.
some drag racers use lowering straps to compress the front forks so they can launch harder without flipping it.
i've seen a firebolt on display with the chin faring practically on the ground. (me thinks the froks springs were removed) it would be a rough ride with that set up, but looked cool.

so that's why i asked why. but im glad you found a higher suspension set-up that your happy with, for whatever reasons you chose it.
