Back on the topic (⚙️).

I’ve tried a non-Mtorque map with my SF. I’ve been waitning for the Akrapovic map (Mtorque) but since it’s been delayed I then went for a regular one (Termignoni SD199) and where quite happy with it but still missed the animal in it. Better but still sane.

Today I bought the Arrow Mtorque (sans db) and installed in the bike and man - it’s as if the bike is doing crack and completly transformed just in the insane way I was hoping for.

Revs faster, it’s angry, feels lighter and powerwheelies in 1-2-3 and felt like in 4th as well.
Need to ride more to tame both me and the bike but I’m impressed. Try it! I’ll get back in a few weeks with a better review.

I assume you run Arrow exhausts too? ( and NOT the standard exhausts)

So it powerwheelies in those gears with DWC turned off or way down?
 
Nope. I have the Akrapovic slipons on my bike, meanwhile I’ve installed the Mtorque for Arrow (UpMap recommended that one) and it works well.

The DWC was enabled, low setting but still hoisted the wheel.

So to be clear. T800 + Mtorque map on SFV4s with Akrapovic slipons

Sounds good then! I installed the T800 UpMap MTorque for OEM exhaust and it is nothing to write home about... I have now installed the 14 tooth front sprocket - it runs 5175 rpm (approx) @ 100 km/h compared to the 5000 rpm @ 100 km/h with the OEM 15 tooth. So not really any "gain" there... Regards!

Did you get more torque with the 14 tooth?
 
I am actually just adding a bit more revs.... it feels slightly more torquey. One should go up a tooth at the back too (but I hear of ecu issues over here...). My guess is that going from a 60 profile rear tire to a 55 may be an option too. Has anyone tried this??

I will for track days, Once I get there I'll post my thoughts
 
Great! Thanks!!

I got a call from the National Ducati importer and distributor over here.... Asked a few questions why I intend to change ratios and then said that they took a EU spec Streetfighter V4S (2020) owned by the company director, went down a tooth up front and +2 at the rear. They ran into "electronics" issues that they could not get corrected - QS had issues etc. They did a re-calibration on the bike but eventually just went back to OEM..... So now I'm cautious... Regards.

I have the 2021 Euro5 SFV4S and I have gone down to 14T which makes the bike more enjoyable to ride in the lower gears. I had to do a tire recalibration as the electronics went wonkers after the sprocket swap but its all good after that. I am thinking of going up to 44T in the rear but after reading this, I am quite hesitant to do so.

If the calibration fixed the issues faced after the front sprocket change then there’s no reason why it wouldn’t help with changes in the rear as well.

The same principle applies because it’s calibrating for final drive ratio.
