I like the look of the Akra but there are many great options out there.
My Akra is the Ducati Performance one with the official UpMap compared to the “evolution” system which does not come with the UpMap.
the UpMap is supposed to be engine software to make it work better with the more flowing exhaust, but it isn’t that great. Huge dead spot in the middle of the rev range. The only way you can get it running properly is with a ECU flash created from extensive Dyno tuning. The ECU flash is a mail in service from vcyclenut or maybe you can order a fresh new ECU with the files on it so you can hang on to yours.
sprint Offers an air filter for the racetrack for $350 and a version for the street for $100. I’d recommend the $100 one cause the streets are filthy
I think this mod alone increased a couple HP with factory tuning on the V4, so it actually is worthwhile. You can remove and clean it and it goes back in dry, no oiling like the old K&N
exhaust, air filter, flash. Noticeably more powerful and MotoGP sound.
the next step in noticibly quicker acceleration goes like this:
Lightweight sprockets and chain
CF wheels & lightweight rotors
I feel like this is about as quick as you can get the bike but eventually new Master Cylinders, calipers, clutch slave and Carbon Fiber lines. And of course top shelf suspension
then add a bunch of carbon fiber, then start replacing bolts with ProTi. If it’s still not fast enough you’re going to need a V4
