just weighed my 1098s F/R

Pretty much what I expected.

(Me off the bike with the fuel light on)
Total : Weight 186.8 Kg
Front : Weight 94.8 Bias 50.7% %
Rear : Weight 92 Bias 49.3% %

(me on it feet off ground, no fuel)
Total : Weight 266.2 Kg
Front : Weight 126.3 Bias 47.4% %
Rear : Weight 139.9 Bias 52.6% %

I have stock chain+gearing
But I have moved forks down about 3.5mm so theres 11mm showing above triples as opposed to 14.5mm above triples.

Since I'm not aware of any other bike ever being weighed in quite this way, .....
Next time "(Me off bike with full tank of fuel)" would seem more informative.

These are quite interesting findings. They do not tally exactly with my own, but it's a while ago when I did my weigh.
As for weighing the bike complete (with fluids) ready-to-ride, but with an empty (or near empty) fuel tank - this is how Master Bike weighs the bikes, and their findings are published by many mags around the world.
The weight with the rider in situ is interesting, although with the rider being a dynamic (mobile) weight, sitting position would have an influence.
Other changes on the bike can have an influence on the weight bias - eg. replacing the stock mufflers with Termis or similar removes 3 kgs (almost 7 lbs) from the very back of the machine.

Gimme a chance to fill it up Weighed it with 80% full of fuel too so I could see what influence the fuel load played and here it is:

Me off the bike-
Total : Weight 192.1 kg
Front : Weight 97.6 Bias 50.8% %
Rear : Weight 94.5 Bias 49.2% %

On the bike-
Total : Weight 275.6 kg
Front : Weight 128 Bias 46.4% %
Rear : Weight 147.6 Bias 53.6% %

I do have Termi slip-ons

You're going to have to lean forward further son - You're upsetting the weight distribution!

tell me about it leaning just ain't enough to tame this bitch.
now heres why I know think that ducati runs the forks round 14.5mm more weight forward n it Gets the bike holding tighter lines it won't lift much stays planted but I just can't trail brake that's the catch

I'll move forks back to stock position and do another weigh in.

Thanks for the numbers but what's optimal with rider on the bike? I assume that's what really matters?

Optimal for what task?

I personally believe everything in life is about compromise just like a bike setup.
For me its more about getting rid of things I don't like, rather than asking for more of what I don't need.

A street bike that sees trackday duty.

I've read in another forum +2% on the front wheel. BTW I'm with you getting rid of what you don't like. I'm running DK's ride height numbers now 235mm rear ride ht., 2 lines showing on the Showas, and the front wheel feels WAY overloaded, steering is very heavy.

I'd agree with the 52/48 but who's to say once you ride a bike in this magic number that you'll even like it?

If the bike works fine as is just clean up the steering speed then go from there.

I'm not aware of the lines on showas and I don't use other peoples ride height numbers.
It's all about how my bike feels under me, nothing I've read in mags anywhere has ever suited me as I like to fiddle I'd try it all.

As for your heavy steering tractionless look into this stuff:
Worn tires flat centers.
Tire pressures.
Turn steering damper off while tuning it in if you have adjustable one.
What preload numbers u using and are u measuring them correctly?

I was using the ride height numbers as a jump off knowing the lack of trail issues with the 1098. I planned on adjusting from there but I'm to the point of not wanting to screw it up even more.

Tire pressure at 33, Damper at 3, dynamic preload 35mm front 28 rear. Static measued 1st without load, then measured again with rider.

If its anything like my s and im not sure it is i would try 40 front 35 rear sags. Or even 35f 35r sags your 28 (pogo stick) rear sounds too much your swing arm angle would be pitching the bike forward all the time more so at road speeds

Hi TL,

From the sound of it, you raised the front up about 5mm, while raising the rear about 7mm. IIRC, you don't get any weight bias, rake or trail benefit, while at the expense of a longer wheelbase of ~1.5mm. Also, with a higher CofG, the turn in will require more force. This is probably why you are having a harder time in the turns, but probably feels more stable once the turn is initiated.

One note to point, altering the front has more of an affect on chassis than the rear, so even if you change the rear to offset the front, you must increase those changes more than 60% than the front.

Just a suggestion(Always understand, this is a baseline and must be fine tuned to fit your riding style): Leave the front where it's at, as it aids in your swingarm angle, but increase the rear ride height an additional 12mm from where it's at. It should put it to 247mm. This will transfer some of the weight back to the front, increase your swingarm angle more, reduce your wheelbase(~3mm), reduce your rake and trail slightly.

Even though you have less trail than stock, the reduced rake and transferring some of the weight bias back to the front again will aid the bike's ability to hold it's line, giving you more feel than stock and relieving some of that hard initial turn in. The higher swingarm angle will aid in anti-squat, reducing load transfer when accelerating, making the bike hold it's lines better, even though the trail has been reduced.

What will make it better? Lesser offset triples. In your case, based on you following the above chassis numbers, anywhere from 29-32mm offset, compared to 36mm stock, with 30mm working well in this scenario.

This will reduce the wheelbase an additional amount of MM in relation to the reduction of offset, allowing less lean angle for a given turn radius. This means less work for you.

I hope this helps.

My 2011 1198SP weighs 183.7 Kg (405 lbs) all fluids & full tank ready to ride. I don't have the actual F/R weights, but I think it was 51/49 Front/Rear.
