Does anybody know what the weight distribution is on the Ulysses, front compared to back? It seems like there is not enough weight on the front. I've had to crank the rear preload up to get the front end to settle down. The front end squirming / instability seems to be worse since I installed new Michelin's.

Yes, I know EXACTLY what it is on my '06. I have the numbers at home (posted on my shop wall);

I called Mrs. Greg to look them up and here's the deal:

ULY wet weight (full of fuel; can't recall if I had side bags on or not but I don't think so):

F: 245 lb
R: 270 lb

TOTAL: 515 lb

So the F/R bias is 48/52.

P.S. These are from bathroom scale; highly accurate (error induced by angle is extremely small). Do it yourself and see what you get...

Thanks for the info. I think I will try to weigh my Uly. I guess I need to spend more time finding good suspension adjustments for my weight, riding style etc.

Bushido- might be a good idea to check the tightness on the steering head bearings too. Looseness there can cause instability.

Thanks for the suggestion. From the first time I rode the bike it just seemed light in the front compared to the bikes I have had in the past but I have just adapted to it but then I put on the Michelin Pilot Road 2's and I have noticed it again. I was coming home from Mid-Ohio on Sunday and it was the first time I put many highway miles on since the new tires and I noticed the front seemed to be dancing around and I experienced some wobble and weave in a long sweeping exit ramp running around 80mph so when I got back on a straight stretch I reached down and cranked some more preload into the rear shock and that seemed to calm it down some so that got me thinking. Dr Greg said his was around 48/52 but I wonder what it is with a 180lb rider on board and how that compares to other models or bikes. I believe I read somewhere that the 1125R has a more forward weight bias? In any event it is not a big deal to me, I love the bike ( although it is a little tall for me, I wish they had the XT out when I bought mine )but it just made me wonder how other bikes compare. Thanks again for the suggestions.

Bush,
Perhaps you need to put on some weight?

Are you familiar with the beverage called "beer"?

I've noticed a decrease in stability with my PR2s also, but it's nothing I can't live with. I know my steering head bearings could stand to be replaced, but I've got bigger fish to fry right now.

Y'know, when I fitted those tires (I ended up liking them just fine) I felt the same way. Either it went away or I got used to it. Or both.

I've noticed (particularly with the D616's I can't wait to be rid of) that a slight (2-3 lbs.) decrease in air pressure up front will make it feel decidedly squirmy.

Dumping the Dunlops soon - back to the OEM Pirelli Scorpions.

I guess I need to get out and put some miles on those new tires. I will just tell the wife I have to go ride err "fix" the Uly, might take awhile!
