I Ride: all the bikes....
FREE Suspension Setup advice from an expert

I have found in life that you generally get what you pay for...my aim is to give something worth a lot away for FREE - on this forum. In person tuning is a different story... I am posting this thread to give back and to help people because I read through some of these threads and I routinely see information that is not accurate.

On this thread I will answer questions to help sort out your 848/1098/1198 and all Panigale setup basics and/or issues you may have.

I have been setting up bikes for 20 years for all sorts of riders and I have been very successful in doing so. I started down the path of learning how to do pretty much everything on my own because I didn't want to have to rely on others to fix my bike and I don't want flat rate mechanics who don't care about my safety cutting corners; I have experienced both situations more than once.

I have learned from folks like Dave Moss and David Behrend and setup supermoto, motocross, flat track, mini motard, road race and street bike :-)

I am a WERA and AFM racer with top 5 finishes in expert superstock/superbike classes on bikes that I build from scratch and I even won some championships on Ducati when I was a younger man.

I am starting this thread to help so let's get to work...

I have a Ducati 959 with stock front forks and rear shock. I am 185 pounds and have not touched my suspension since the dealer set it up.

Most of my riding occurs on the street with 3-5 track days per year. Overall tire wear has been pretty even and smooth on the track (can post pick). Front end feels a little vague going into slow corners, overall corner exit feels good.

Any advice would be greatly appreciated.

@louis041, nice to meet you. What tires and pressures are you running? Are you 185 lbs with or without gear? Do you know what the dealer did when they set it up? Most dealers don't touch the bike so if your dealer did some things you might be ahead :-) Have you set bike/rider sag? If you do not know what that is, no problem, I am happy to explain here. Tank soon.

I'm running Pirelli track day tire front and rear, on street tire pressure front and rear is 32. On track I run 30 front 28 rear hot off the warmers.

185 without gear, as far as dealer set-up they asked me my weight when I bought it. Didn't have me sit on the bike so might not of touched it at all.

I have not done sag measurements but I can this weekend. There's a good motorcyclist magazine video on it.

@louis041, ok so I recommend 40 mm front and 30 mm rear rider sag. Bike sag should be about 25 mm front and 12-15 mm rear. Remember to take the average between measurements of you sitting on the bike with the suspension compressed and released slowly and suspension lifted and released slowly.

RaceTech explains this here

Your pressures are a bit off. Try the following....

Street pressures for Pirelli SP/TD: set at 32 PSI front and 28 rear COLD

Track pressures for Pirelli SP/TD: set at 32 PSI front COLD or 34 PSI hot off the warmer, set rear at 25 PSI COLD or 28 PSI HOT off the warmer. When you come in from your session IMMEDIATELY check the rear. It will likely be above 28, bring it back down to 28. After the next session check it again and repeat this process until the pressure does not go above 28 PSI HOT OFF THE TRACK.

Generally, most riders do not brake hard enough to generate enough tire flex to raise the pressure more than 1 PSI so you really don't need to worry about front pressure once you set it in the AM.

Here is some Pirelli info

Thanks for volunteering

I've got a salvage auction V4S that I've turned into a trackbike. A while back I did a shakedown trackday at a slower pace to feel the bike. I set sag to 37mm front 28mm rear. I left everything stock with the exception of Pirelli TD tires(34 front 27 rear off the warmers) in place of the SPv3 tires. I weigh 192lbs without gear.

I had two suspension issues. I was blowing through the fork travel until I added two turns of preload and took the front compression setting to 3 'turns out' in the fixed settings. The bike also required quite a bit of pressure to initiate turns, which isn't surprising given the 16mm diameter difference between a 200/55 TD and a 200/60 SPv3.

I'm heading to the track again this weekend and have made a couple of changes that I think will help out. First change was to the forks, bumped up to 10w oil and the level is set at 170mm vs stock 230mm. I'm hoping this pushes me more towards the middle of the compression adjustment.

In the rear, I lengthened the shock from 312mm to 317mm in order to compensate for the 8mm difference in rear ride height from the shorter 200/55 TD.

I'm hoping these changes make sense, as changing them at the track is a bit of a pain.

Thanks for starting this thread! What's your reasoning behind 40mm front/30mm rear rider sag? Would you recommend that for a trackbike?

That's very noble of you, you're a gentleman.

I'll have two bikes to ask about,

Bike 1 - Panigale 1299, standard suspension, only used for the road.
Rider weight- 240 odd pounds.

Thanks for offering to help, this lost souls

Here is my question

I have a V4S

180 lbs with gear

I ride slow to medium expert pace



Was having trouble with the front coming up really easily, and front headshake

Dialed 3 turns of preload on the back, and this helped a ton.

Just wanted to confirm with you, if this was the right route to take.


Next I plan on putting 2 turns of preload on the front to prevent diving during hard braking

What are your thoughts
