During the spring I had a prostate surgery, and was not able to ride my Hyperstrada 821 for 3 month.
So instead of driving, I did som upgrade.
Starting issues.
As I posted in a previous post, I hade some problems to start the engine.
Changed to thicker cables and a new start motor (Parts-Unlimited) made it better, but not perfect. Still hade some issue with to much petrol/too less air. Smell of petrol durin start up.
But the start motor sounded terrible, so I decided to change it to a Ducati Start motor, 27040107A. Much better.
Slip-on
Changed the exhaust to a G.P.R Furone.
I like the sound a lot.
Air intake Kit
The hole in the original air intake cover is relative small, and to achieve more air in to the engine I found an Air Intake Kit from Giuseppe Starace. Search for "Giuseppe Starace air kit Ducati". You can contact him on Messenger.
Together with a new air filter from Sprintfilter.net, the air flow to the engine should now be as high as possible.
New map to the ECU
More air in and more exhaust out, so I had to fix a new map to the ECU.
Found it on UpMap
They have 6 diffent maps for the Hyperstrada 821, and I choosed ”H821 13 D133FD BOX” after recommendation from the company.
I hade some trouble installing the map, due to no existing VIN in the ECU, the dealer did not remember to put it in when changing ECU in 2014. Finally manage with a very very good support from up-map.it
Removed the lambda sensor and unplugged the exhaust vale cable.
The result
I can really recommend the map from up-map.it.
And for you that has a original air cover and original exhaust and want a better drivability and easier to start the engine , there is also a map for OEM. Could maybe solve some of your problems.

The result
- Higher voltage to the start motor, made it turn a little quicker
- Much easier to start as the initial rpm is a little bit higher than before, for about 2 sek, due to the new map. Seems that the throttle opens a little bit more than before. No problems to start over again, cold or hot. I am very happy about this, as this was one of the biggest trouble before.
- Better drivability, especially in low and medium revs.
- Can now drive at 50 km/h in 6th gear = 2000 rpm. Not at all normal for a Ducati. No studdering.
- No suddenly engine stop by red light.
- Easier to start and drive away.
- According to the map spec, +5 bhp, +3 Nm.
