Bike Setup - Ducati.ms

otisthelab · Jul 17th, 2010, 11:43 am

I am new to the Forum... I have an '08 Hyper 1100 w/ DP Seat that I am trying to get set up. I am coming off dirt bikes (KTM 400 MXC) and am having trouble getting the bike set up, so I was hoping you guys could help:

1) When I ride, I get a pain in my right wrist within about 10 to 15 min. Its on the upper outside, right in front of the lump of wrist bone. Is there an adjustment to the handlebars to correct this? Left arm is fine. (I keep 2 fingers up on the front brake lever quite a bit but I wouldn't think that would be the problem).

2) Suspension: Do you have a recommended suspension setup? Street riding / no track. 200 lbs w/ gear and 6' 0.5" height.

Thanks and I appreciate the help.

for wrist pain, I'd look into the lever heights. Racing MX, you learned quickly that you can change the amount of pain/arm pump by the angle and height of the perches. Hence why I don't like shorty levers.

for suspension, I'd have your suspension tuned by a local suspension place, or have it redone (expensive $$) by thermosman or a few other places.

I recommend highly using the search function

I did do some searching, but most of the stuff I came up with on suspension was for track riding. I am just looking for street. The Duc shop said factory setting was fine for my size, but I am not very adept at suspension setups. I had my dirt bike suspension revalved which was awesome, but am not going to spend $$ on this one for that. I did come up with this, but am not sure of its validity:

Front: spring preload: 1 line showing; Rebound damping: 4.5 turn out from full stiff; compression damping 3 turns out from full stiff; Ride height 2 lines showing:

Rear Spring preload: 31.75 mm from top of spring to top of thread; Rebound damping: 20 clicks out from full stiff; Compression damping: 4 clicks out from full stiff

As far as the levers / wrist... I think I have the lever right, but am suspecting handlebar is too low. However, my searches here indicated that raising the bar 20 mm didn't help others much. Was hoping to get imput on whether others have tried that or maybe just switch handlebar to another that works better than stock... Could use advice on that as well.

a good suspension setup for the street would also be a good setup for occassional track riding. Unfortunately, if you achieve the proper sag numbers front and rear, you would have put too much preload into the springs.

I had my shock rebuilt by traxxion dynamics and I installed fork springs from racetech. There really isn't anything that you can adjust on the stock stuff to make the suspension work the way it is supposed to. I also weigh 200+. The springs in the front are .68 kgs, racetech recommended .90 kgs. for my size.

I wouldn't just go off of numbers that you found somewhere on the web. You will need to measure sag and adjust accordingly. Then it takes a trained/experienced person to get the dampening adjusted as close to good as the stock stuffTwill let you. There are some articles available on the web to help you out.

I think you are having the same problem I have had with a variety of bike handlebars. My problem results from too much sweep i.e. the ends of the bars are angled too far back, putting pressure on the outside of your hands.

I have found two ways to deal with the problem. The first is to simply loosen the bar clamps and rotate the bars slightly toward you. That way the horizontal angle takes on a vertical element. Of course, make sure you still have clearance at full lock right and left. The second choice is to replace the bars with bars that have less sweep. You can see the sweep dimension is E on this chart.
