I think the Aprilia RSV4 Ohlins are between 95mm and 110mm.

The stock air gap is for a road fork. If you're hitting the track, try less air gap in 10mm increments. Is stock 200mm? I probably wouldn't go less than 160mm, but would be interested to hear what Ohlins recommends as a minimum.

Ohlins certified mechanic basically means he can change springs and paid Ohlins to check he can, so he can have an Ohlins certificate. A mechanic with race experience and experience of the effects of changes made to suspension would be more useful (and sometimes they get the Ohlins certs too!).

Thanks for the info regarding road vs track air gap. I'll check with him and see what he recommends. He works with the national superbike champion, and has a lot of experience with previous Panigales, however not so much the V4. I trust he knows what he's doing, we just need to find out what works for me.

The service manual lists the gap for an '18 V4S at 230mm, which at first glance seems large until you take into account the volume of the servo.

Where is that in the service manual?

ETA: Found it. Its under "Fuel, lubricants and other fluids.pdf"

What you may find, is the very fast riders have a larger air gap as they don't brake as hard at the end of their braking (they carry more entry speed).

the guys at NBD says per this spec sheet the stock front fork springs are 8.5, so a jump to 11.0 would be a pretty robust increase.

I’m dubious about whether the front springs are actually 8.5 stock though…as this spec sheet is for a Streetfighter….the Ohlins are the same part number on both the Streetfighter and the Panagali…but I’d be surprised if they had the same inner springs, the SFVS that I had before the 25 Anniversario 916 had a much softer front end than the bike I’m on now.

We will call Ohlins for a follow up and verification tomorrow.

I also ordered some scales to weigh the bike and the cars with, pretty interested to see what we got the weight down to.

BP PanigaleV4S · Sep 13, 2021

Can you get a spec sheet like that for a 2020 or 2021 Panigale V4S?

I'm very surprised the spring rate is 8.5nm on the Streetfighter considering everyone says the Panigale V4 is 10.0nm.

ETA: I think that's a work order sheet.

Taz · Sep 14, 2021

The mechanic who worked on my V4 SP confirmed the OEM front springs were 10.5 N/mm, and said it was the same for 2020+ V4S. Perhaps the streetfighter has softer springs?

that’s what I’m thinking….and to complicate things a bit more in my particular situation, I have the 2020 25 Anniversario 916 addition of the V4S, which is one of those parts homolgation numbered bike specials…seems like they were trying to build a V4R with the bigger V4S engine, so it has a lot of V4R bits on it from the parts bin, including suspension components, and to complicate things even a bit further, they released it as a 2020 bike to be on the 25th Anniversary of Foggy’s Championship, but it has mostly 2019 parts, including the 2019 engine mapping before they softened up the tune, and it supposedly has the suspension geometry of the V4R.

The rear spring that came on it was a 95, not the 85 of 2020 and newer bikes. So I suspect that whatever spring is in the front forks on mine is the same spring that came on the 2019 V4R, and we’ll need to adjust from there, not from whatever spring that came on the 2020 Streetfighter shown in that spec card.

that’s what we are waiting for confirmation on.

turns out that spec card is NOT for my forks, the part number for mine is FL 946 0

which the Ohlins guy just told me means mine has different valving, springs, etc

will update in a bit

Hey Steven, is Moto Club doing the work on your bike?

Nope, the Ducati Dealership…there’s one guy in their service department that I have a very good relationship with.
Dunno who MotoClub is?

endodoc · Sep 17, 2021

Moto Club is a shop in Santa Monica. There is a V4 in there on their floor with Thyssenkrupp wheels and looks to be Sicom rotors.

Ahh cool, no not mine, I live in Orange County so that’s a little far north to drive for service for me

my bike is on the way here from the shop, am about to go do that Sicom bedding procedure….pretty excited to see how she feels

endodoc · Sep 17, 2021

Ha good deal, we’re in Newport Coast when we’re not in Idaho. Like to check out the bike sometime. Interested to see the break in on the Sicoms. I probably won’t get to putting them or the wheels on until the next tear down.

Steven31371 · Sep 17, 2021

got er home, bout to go ride her a do the bedding process for the SICOM rotors…

Cycler (member here) hooked me up with my sprocket sets and chain, they look great and tie in well with the red/black/white livery of the bike I think.

weighed the bike, came in at 413 pounds with a completely full tank of gas…it has a lead battery in it, will put the Lithium one back in after we are finished adjusting the suspension, I think that will get the bike to a wet weight of under 410 pounds.

right on, I’ll message you when I’m heading over that way to Ducati or something.

or stop by the house, I live in Laguna Hills ;-)

attached is the SICOM bedding procedure, the guy called me from England to make sure I follow that to the letter lol

Steven31371 · Sep 17, 2021

So 1st impressions on the recent mods….the 15/43 gear teeth setup is PERFECT for me. At my weight and with Wheely Control set on 3 it accelerates so F-big hard but controlled, and wow, what a difference the right rear spring rate for my weight makes on hard accelerations…it’s the 1st time I’ve felt completely comfortable doing full WOT accelerations on the bike because before the rear ended was sitting down too much.

Between taking about 20 pounds off the bike and changing the gearing this thing got a lot funnier to twist the throttle hahaha

the SICOM rotors made a noticeable difference on turning, between the CF wheels abs those lightweight rotors I literally just turn my head on 120 mph sweepers on the highway to turn the bike, and with more lean the bike just dives in with no effort at all.

I didn’t make too many adjustments to sag or the DES stuff yet because I wanted to ride on the new springs and settle them in a bit….tomorrow we’ll work on that stuff time forgiving.

there is one last mod I’m going to have to make on the bike, needs the more aggressive 17/19 brake masters now, I like a firmer brake feel and things definitely feel a bit more squishy with the new rotors and pads. The brakes themselves have a lighter initial bite that’s progressive but then grip hard, all of which is good, but the lever itself feels a bit more squishy.

How many miles have you put on the bike I’m wondering how often you’ve got to maintain those dry clutches.

I replace mine every 3k as general maintenance.
