V4S suspension

I set the sag to 25 mm front and 15 mm rear (rear shock has 10 mm of preload according to Dave) which is the same as Dave did to my 1199S.

Full "out" on the forks was 28 (short) turns on the left leg and 15 turns on the right.

I got the desired sag on the front with 12 turns on both legs.

The rear shock I turned out two full turns.

Although I got the sag I wanted the spring rate is still too hard for my liking.

I haven't played with the (dynamic) compression and rebound, .... yet.

We will be on the track July 8th so I will be able to get a better idea of how she works.

FYI, I am about 190 pounds with gear.

I, too, would like to hear Dave's comments on the S suspension.

If the suspension feels stiff when riding and your sag is fine, look at your compression damping.

Dumb question. Can you just turn the preload adjusters on the front fork? Seems like those rubber caps would turn with the adjusters. Manual says have the dealer do it. I have not even measured my preload yet but do not want to touch those preload adjusters on the fork until I understand how to do it.

Think I figured it out. Pull the rubber caps back. Disconnect the wires. Adjust the preload. Re-connect everything. Is that right?

Yes, it is actually quite easy once you figure it out.

Set the sag on my V4s yesterday. Used the Ohlins method where first you measure the full extension of the fork with the wheel off the ground then the extension with both bike and rider. So that includes the free sag of just the bike. I grabbed some setting from an R1 online which is probably ball park. Free sag with just the bike was around 30mm FYI which is also in the ball park. Ohlins lists between 30 and 50mm of sag with both bike and rider. I set mine at around 40 which is 5 turns in from full out on each fork. I measured approx 14 turns of adjustment on each fork. Mine came from the dealer at 2 turns in from full out and felt OK for the two rides I have done. Certainly not too harsh. I have not found anything online about adjusting the sag on these particular forks.

I've had the V4S for 4 days now, about 275miles on it all by me
Did open her once, some backroads but not pushing it at all... I am 5'10" 175lbs and the suspension is definitely more for track right out the gate, preload could be taken out just a turn or 2 but out of box it was still good for street, and Maryland/DC roads suck including the highways lots of bumps. The dynamic suspension seems to be doing it's thing just not on the very first bump or 2 if you switch conditions. But out of box I would say it's ready to hit the track for my weight... Dynamic suspension just needs to kick in.

As for the grips and riding position... it's freaking perfect for me; I was a little pissed they didn't have adjustable rearsets for this but the feet higher up and everything locking into place naturally is what I go for and usually try to do on my bike anyways. This just made things easier to hold onto w/ the thighs when riding.

new trailer is out for V4S suspension evaluation, the full video is on their site but you have to subscribe. I watched the full video off their site and he said the stock V4S rear suspension spring rate is too much for anyone under 180lbs. Dave had to remove 3 turns to get some static sag in the rear. Given that, the stock spring rate that comes on the bike is 95 N/mm which is rated for 160-180lbs. How come Dave had to take almost all the preload out for a 180lb rider? I weigh 160 and I'm trying to see if I need something softer in the rear. I'll have to measure sag tomorrow to see where I can get it.

So, we did our first track day

Power: Coming from an 1199S with full Akra the V4S is not that scary fast.

DWC: You can do AWESOME loooong wheelies out of corners and look totally cool doing it! 😎

DES: Work do do here. I set the sag at 25/15 but the rear is still way too stiff the front is diving significantly.

I have now set it up using Dave Moss's most recent excellent vid on the subject.

Interesting that we have two very separate choices, one totally controlled by you and one (after setup) totally controlled by the computer.

More playing required, I think. 🤔
