The V4R service manual I have is for the 2023 V4R bike. At least they updated the pictures anyway. Ohlins gives the spec as 310mm +4/-2 so 314mm max. At 316mm you’d be past the mark on the threads, which I thought was there to indicate max safe length.

Holy $h!t, Andy has been shouting into the wind haha!!!

Same same. Not sure where Andy's fat fingered 316 mm comes from but who cares tbh

2023 V4R // 2023 SEASON

these are Ducati Fairings, I just the new Speed Carbon fairings in. I will post images today Have you found any fairings (besides the Ducati branded fairings) that fit the bike with the STOCK exhaust? Motocambri has a bunch of choices, but they are all for the RACE exhaust. Yes, First Gear...

What does MotoSpec say?

MotoSpec went out of business after you started publishing your spec overlay images of on the internet.

I wonder if this was an Italian factory one off or by intent. Looks a tad too long.

Yeah that ring delineates the max length. But then again let him fafo

That's what I thought. If I tried to adjust the length so that ring would show past the lock nut there was a very obvious binding to the threads, almost as if Ohlins was saying stop.

It seems the Ohlins spec, 310mm +4mm/-2mm seems to be on the money.

I took a snapshot of this back in 2022 from this site. The interesting part is that it was some semi-famous fast guy, I forget who and can't find the thread, that was fast using a V4S in its dynamic mode. My maxing out all of the dynamic settings, you'd just be letting the bike adjust more.

Warning

The shock absorber has a maximum distance indicated by a groove on the threaded section of its eyelet.

Warning

Once the maximum centre distance has been reached, the groove is aligned with lock nut (5) when this is tightened.

If, with lock nut (5) tightened, the groove protrudes with respect to the lock nut, the shock absorber centre distance

used is NOT CORRECT (too long).

I can’t believe the internet hero doesn’t have any practical experience…

Yep see all this being mentioned 12 months ago

Spooky….. @spooky take a picture of the bottom eye of you shock and post it please!


What you will see is a std factory fitted ttx with a length eye to eye of 315/316 and the bottom lock nut tightened way beyond the threads on that wide space marker!

and if you read ALL the blurb on the release brochure for the 2023 V4R you will find..

I think SD summed himself up when he said, and I quote, "im not sure!" he should of left it at that!!

That was just a random 23 v4 R when they were first released

Check these two out on a factory bike with just some race pads, set sag and usual fork adjustment. 2-3 seconds off their race bike times. Yes, these guys are body steering the bike because counter steering while leaned over is asking the tire to do opposite things. While gyroscope precession will roll the bike opposite of bar input, the tire is also now pointed outside of its balanced arc/path which reduces total available grip. Be careful doing this because you will tuck the front. If the bike wont tip in, you either need to drop the front end more or look further around the corner. If you are paying attention to lean angle with peripheral vision, you'll never hit the angle. If you look well through the turn and think about going faster, you'll start dragging knees and elbows without even trying because the angle is coming to you, because of speed.

Also, riders at this pace are professional athletes, think hundreds of single legged pistol squats a day and probably as many miles climbing hills on a bike. The pegs are high because they are insanely flexible and it allows a shorter rider to get further off the bike on the opposite side. I have a Fireblade and that thing from factory makes my R6 look like a sport touring machine! That bike is also way above my ability.

The OEM's have to gear a bike towards the masses, that is what sells. Honda has a CBR for the street/canyons and homologated version RR-R for track work, club and pro sanctioned racing, not a single common part between the two. I wouldn't spend too much time on the nuts and bolts at our level, just more on flexibility, strength and stamina. Again, the video below on stock production bikes! I promise you, these two are not thinking about rake and trail.

No Ohlins!
