V4S ohlins spring rate? Dave moss

Hey guys, has anyone watched Dave moss new v4s suspension evaluation? He mentions the rear shock factory spring rate is way too stiff for anyone under 180lbs. And the spring is rated for someone 220lb+. Iím 160lbs with gear so I wanted to look into a new rear spring. Called up my dealer and they said the rear spring that comes with the bike is the 95n mm.. which compared on ducatiomaha site, thatís for a 160-180lb rider? So now Iím confused. The rear spring is the one thatís good for my weight already. I have no my measured sag yet. But I will later today.

Itís just confusing as Dave moss mesured with his helper at 180 lbs, and said itís just barely enough for him with almost all the preload out the back.

Any input thanks!

Do YOU think the rear is too stiff? If you aren’t experiencing issues with it, why bother swapping it out?

What works for some other rider may be complete shit for you. I think you need to have a similar riding style and skill level to start comparing suspension settings.

Just my two cents

yeah the rear is sorta stiff for me, I went over a manhole bump in the road and I shot up. Id say thats a little too stiff? In the video he was saying the factory preload from showroom has 0 static sag in the rear, he had to take out 3 turns to get some.

I totally get how that works with suspension settings and other riders style. I'm just looking for the best baseline for my bike and adjust it to my weight, then see how it handles.

Try softening your compression setting a little. The stock settings for me were very good at the track based on how it felt and the tyre wear but was way to stiff on our shitty roads. You will need to do the rebound at the same time

thanks for the input. I'm going to play around with compression rebound for the street. So far I have the sag both static and rider within range recommended by ohlins. The rear needed 3.5 turns out of the preload for my weight. Feels a lot better now in the corners for sure!

I Ride: V4S and Ninja 400. Dichotomy.
It's all subjective and different tuners will have different opinions and recommendations. According to Ohlins, the 95 rate is not too stiff. I'm 185 and I have found the stock 95N/mm rate is fine for me on the track. The way to know is to set your sag, and if it's within the range of ideal operation then the spring should be functional. If you can't get it in the ideal range of operation, then it needs to be changed. And even the "ideal" range is subjective, we recommend 25-40mm as the effective range for rider sag in the rear. If you're in that range, the shock will "work" fine it just a matter of preference for feel and riding style beyond that. You'll find many top racers prefer a spring rate that is a lot stiffer or softer for particular tracks they race on, they could care less what the recommended spring rate is for their rider weight, because the other forces on the bike from braking, acceleration and cornering have a lot more impact than the weight of the rider. So just keep that in mind, this is not an exact science. The advice above was spot on, don't change anything on your suspension unless you have a reason to do it based upon how the bike is responding while you're riding it. The rest of it is just chasing your tail.

I watched the video and I agree the rear is too stiff with the stock amount of preload. I am going to take out all preload and see how it responds. I am 167 lbs (76kg) no gear.

That makes a lot of sense! I appreciate you taking the time to explain all that! I just went off dave moss as he's the expert in suspension, haha. The bike definitely feels better once the sag was adjusted to my weight. Still needs some tweaking in compression and rebound, but I feel like I have a pretty good base now. Thanks again for clearing things up for me!

if you are riding your bike on the average road,don't weigh 150kg and dont ride track, it is way to hard.
