Where are these fields? I live inside the loop (Montrose area)... kind of a drought of good riding roads.

the area where I went doesn’t qualify as great riding roads, just desolate.

the bestriding roads are all above 290, NW of Houston and also New Ulm, Round Top and towards Somerville. Not canyons or seaside of course, but At least there are some turns there.

Installed mine today, I did it myself then rode to the dealer in limp mode. Exhaust install was easy, so was removing the exhaust valve. Removing all of the emissions junk was a bit annoying, you have to remove the airbox, including the shower injectors and even the throttle bodies to get access to some things. They didn't have instructions for removing the sas valve, although they included the block off plates. Annoyingly, they didn't included something to plug where sas breather hose to the airbox used to go so I just used a large screw in hole to the airbox to block it off. Anyone else notice this?

I don't notice any difference in power or improvement in throttle response, maybe a tad bit more. Comes up in 3rd right at 7k rpm, but it always did that. It rides noticeably rough below 3.5k rpm now, it's definitely running much richer, not an issue, just adds character.

Sounds awesome, although a little louder then I hoped, it's a bit much in the city.

The finish on the tail pipe and under side muffler are really nice, but the pipes not so much. I ended up using some scotch brite to clean up the finish and it looks perfect now.

I do like the looks much better in person, it's really mean looking. And now you can tell it has a single sided swing arm, and my BST carbon fiber wheels!!

I wish the bike revved faster though. I want to get a lighter flywheel. I'm at mx guy so my baseline is my 450, which hits the rev limiter in like .3 seconds

Ha! I can only imagine if this thing rev’d like my 300 2stroke.

All my buddies run 300 2smokes, I prefer my 450 any day, even in super technicial woods, there's just something special about that instantaneous torque at any moment. I have a full yoshimura on my crf450rx, with the dual exhausts. It's my favorite exhaust system ever, and I think the best sounding too.

Thanks for sharing your progress!
do you think will get too difficult to switch back to original pipe again?
I’m asking that because in the future I may need to do inspections I my country.

For now the installation is being done by dealer, it will leave the “office” with full extras including the Evo Line.
But they are struggling to get it working 🤒, this post bring some hope!

No doubt this looks much better that the original, the bike gets really incredible in terms of aesthetics and that was my main reason to get it.

It also sounds great, but as you stated, I’m afraid it gets too loud for daily usage in the city. I always has been a “fast & discreet” 1000 R guy 😂.

Cheers

What are they having issues with? It's not hard to install... My dealer was a bit confused on how to install the map. Btw , have the unplugged the turn signals?

Going back to the stock exhaust should not be to bad if you don't care to reinstall the exhaust valve and emissions stuff, although it may run a bit rich.

For those who have the Akra evo and the map installed, does the bike struggle to cruise at 3000-4000 rpm? Not sure if its normal or not. As long as there's a little load, like a very light acceleration, its very smooth at low rpms, but if I want to cruise down the street at low rpm, its not happy. Its hunting, popping surging, etc. Not a huge issue, it sure gives it character.

That doesn’t sound right.

Has the dealer ever installed any Akra map on any model before?

I know when my colleague had the full akra kit put on his Duke 690 - the idle was way to high (and there was some other strange behaviour I can’t remember). It was the first time the dealer has done the akra map - it was sorted a few weeks later when he went back and the dealer had KTM on line when they re did the map. I did my upgrade much later however I did all the mechanical work by installing the exhaust, camshaft and new air box. I just had the dealer( different than my colleague) do the Akra Map - went with out incident.

With your 2020, what other mods does KTM provide/recommend (other than the exhaust) for the Akra map?

I did the kit exactly as intended. Just removed the carbon canister, and all of it's hosing, as well installed the block off plates and the associated hosing for that. The dealer didn't know how to install the map, but he did some research and I watched over his shoulders press all the buttons on the tablet to do the install, which seemed super easy. All he did was select the map associated with the akra evo exhaust, which is what I have.

I did play a little more with the bike today, and I do now notice a bump in power in the mid range. Before, with the stock exhaust, the bike pulls hard at low revs, then has a slight dip in the mid range, then comes back again at higher revs. This is all gone now, it just pulls harder and hard with higher and higher revs, no more slight dip in power. So it's definitely better in that regards.

They are having issues with the turn signals. As far I known the map installation is not an issue at all.
Today I got all the material to implement the magic-box! Let's see where is goes :)

No there's no need to disconnect the head light nor the tail light only the turn signals in Greece the full system cost around 2600€ including map and installation at least in Greece. I dont know the rest of the Europe but my dealer installed the full system and everything worked great i also installed the magicbox and my turn lights works great also.

Thanks for clarification.
Finally I got it working!!! :D
And that would never possible without all the invaluable info shared by you all! Special thanks to @kmanou which was my base tutorial as my intention was to keep the original cables untouched without cuts.

The map installation was easy and so far the engine works flawless with it.

But the signals trick was an impressive challenge.
After lots of trial and error, we got it functional, after all my bike electrical installation colors don't match the proposed connections @kmanou, in my case the yellow and brown are switched in 3pins and 2pins :)

Tip: use a multi-meter to test circuit continuity ;) - If you have 12v/Ground switched, if you test continuity on the "Normal Open" pins of the relay with bike OFF, the circuit may be closed (but of course can't be!)
