Cornerspeed made me aware that MWR racing filters had developed an air filter mod that was a big improvement on the OEM filter and housing. Apparently a 4 bhp gain!
Just had word Cornerspeed have it and my Scrambellina is the guinea pig on Monday !! Yes then I can go test it in the Derbyshire dales :angel8::angel8::angel8:
Any one free to go riding Monday?

Rexxer have done the map for the MWR air filters on the Scrambler. Will they be uploading the map too so you can actually take full advantage of the gain in HP?

MWR make awesome filters, I've installed a few on both my own and friends bikes with great results, always purchased from Ian at speedycom.

The chart above from Rexxer is on a stock bike. The air box is quite restrictive and the kit increases the intake area allowing more air in. The Rexxer tune should make more of the extra air available that it's able to burn :) Looking forward to the "guinea pigs" feedback, but from what I've heard already it's a pretty useful mod :)

Well left home 07.00 Storm Imigine was raging further South but the weather was horrendous. Arrived at Cornerspeed to a warm welcome and great coffee. My fingers were red and cold despite halvarson inner gloves, hand guards and DP heated grips which aren't a patch on the Multistrada heated ones!
Onto the Dyno went Octavia then the MWR filter was fitted. Back on the Dyno with the above results.
We were very pleased to have a gain all the way through on the graph, it's gone from 66.44 to 68.61 at the rear wheel. The official figures Ducati give are measured at the crank.
I believe we are the best judges, we know our bikes and how they ride.
First thing I noticed was the sound and the air being sucked in when starting the bike up. As I rode off into the lashing wind and rain I was laughing in my helmet I feel I now have a perfect Scrambler it gives a roar on acceleration and feels quicker to accelerate! All this with stock exhaust mmmm maybe I should treat myself to a performance exhaust.... ? Even more gain! So for low £ a great mod highly recommended. Waiting for a sunny day to test even further!

Hi - Was this with a Rexxer remap for the filter and filter? - or just the filter? - I see you had already had 1 remap - so I assume the redline was with the first Rexxer Remap - rather than stock??

Thanks

Yes, the red trace is stock bike with a Rexxer map. The blue trace is simply after the MWR kit was fitted.
The bike is still running stock air filter so there's potentially a little more to be had yet....

So can this be fitted without a remap and still expect some gain?
I have the high level Termignoni and upmap already installed.

Yes. The original map posted earlier was from Rexxer on a stock bike, no other mods. The gains come from increased air flow into the air box.

Yes Dave. I'm new to this forum and am very aware of rules etc. I've been around for too many years now and abusing these places isn't my style. I like to chip in and help but not push my wares........
If you'd like to drop me a pm I'll gladly help out if I can.
One word of advice though... The kit is a pain in the ass to fit. You will need to remove the airbox.

Will do thanks.I did have a look at your website but couldn't see anywhere to purchase.I think it's only fair to get it from you for your advice.I'd get you to do the PITA job if I was nearer! Cheers.

Hi Dave, sorry. I don't have the resource to run an online shop as well. It is good to talk though ;) Advice is free to, so i'll help as much as I can with the fitting.

On this bike, the stock air filter has remained. The kit consists of foam filter panels that fit into either side of the airbox.
Yes, the tank needs to come off. That's the easy bit tbh. The airbox needs to come out as well.

First proper ride today since fitting. Dry roads, boy it sounds great, a real roar to it, picks up real quick and feels faster. Loving this mod which doesn't cost the earth!! Can't wait to get the Termi on!!
