I'm going to go out on a limb here and say that the design engineers who work on Ducati power plants know what they're doing and PROBABLY didn't design and implement an airbox/filter that is so restrictive that it robs the engine of power, I'm talking seat of your pants dyno power you can feel.
I believe in fact that's more than often the case especially in today's technology, however on the contrary, I do think that's not always the case with every
machine such as with these 1100 air cooled motors. I think if the air box on these were so great to begin with in terms of allowing peak performance that Ducati wouldn't have offered an open style performance lid (pictured below) designed to go along with the performance exhaust and ECU in the first place. While it is not anything near substantial as a set of velocity stacks, an increased flow design that came as an option from the manufacture tells me that there is some performance potential to be had over the closed lid even if you don't believe in anybody's dyno graphs to prove it. The MWR lid as referenced in this thread is going a step further over the DP open style lid.
We can agree to disagree here but properly tuned and setup of course
, velocity stacks do
add performance to these particular bikes. If there's one source who has proven achievements in power with velocity stacks on air cooled Ducatis, that would be hands down the guys at Wasp PUK who have put countless hours of engineering into their kits and have the results that prove the gains with stacks.

If you do some Google searching for velocity stacks on the air cooled Ducatis, you'll see many proven results of the gains, in most cases pretty substantial too. I am sorry to come out with this post but to say they don't make any gains properly setup and tuned on these bikes is false.
I've screwed around with aftermarket filters and with pods, I've drilled holes (and covered them up again) and re-routed intake scoops in various air boxes, but at the end of the day the power gain is marginal at best.
Simply clamping a pair of K&N pod filters to the throttle bodies is not the same thing as velocity stacks, and, you have to have the engine re-tuned in order to properly see the gains as well.
For example, the oversized CA-Cycleworks tank for the 1st gen Hypermotard requires removal of the air box with the replacement of a set of (small) pod filters you clamp to the throttle bodies directly (no stacks). This actually results in a slight decrease
in performance over the factory air box. Again, you can research this however I think you'll agree on this from your experience.
There has been many studies done on the efficiency of various aftermarket filter technologies, and the bottom line is that none of them work as anywhere near as well as paper for removing fine particulates. And you won't see much difference in airflow between a CLEAN paper filter and, say, an oiled K&N.
I am in the same mindset. No doubt that it depends upon the type of riding you do and the particular style of bike. Velocity stacks on an air cooled ADV based Multistrada (like your signature states you own) would probably be the wrong bike to install them on if you're riding on gravel roads where there are a lot of dusty conditions, etc. If you primarily ride on the street and more importantly maintain the filters regularly
, it's usually not an issue.
Must one do intake modifications to their Hyper and am I saying you should get rid of the airbox? Not all, these bikes do ride fine (although a good tune no matter the configuration can work wonders on a Duc!
) with the stock box untouched. My point is that on these particular bikes
, the air box is not
achieving peak performance and the results are out there all over the place to prove it, myself included.
