Really appreciate your effort in making more YT videos. Listen to all of your podcasts religiously, without a doubt I am able to better understand what you’re explaining in these videos than the podcasts. Please keep them coming !!!!!
Keefer you should visit the Akrapovic factory in slovenia, not exaggerating its so clean and high tech that it would rival any Space company / cleaner than top teams in formula 1 aswell, it´s crazy. Would be cool to see you make trips to various companies that makes different engine related parts.
I wish I wasn't as impatient as I am, I paid $10K OTD back in February 🤦♂ And then spent wayyyyy too much for the aftermarket goodies. But, oh well, I love it!
@@ralphgodwin5143 just remember kawi always has really good sales on there leftover bikes. I never buy new models as soon as they come out. Wait a few months then big sales start to happen
The price of these exhausts is getting out of hand. Cost of production of these things is no more than $200. I think the consumers are just flipping the bill for the race teams that use this exhausts for free as they’re sponsored by the brand.
Thank you for this... I have your map in my 24 KX450.. Do you still use your map or you using a Vortec still? I have done the FREE MODS, exhaust,and airbox,and Keefer Map.. love the bike
@@Keeferinctesting I'm leaning towards the Pro Circuit exhaust.. also is the twin air mod worth the big price? or just take the back fire screen off the cage?
@@themodifiedlife2774 It does not add any more power. The TA PF kit has better sealing but if you have a 3D printed cage already and had good luck with that, keep it.
Great video dude, but we need to get away from this "back pressure is good" idea. That was a salesman keyword that has no place in the real world. It's dyno and track proven that back pressure in a 4 stroke exhaust only hurts performance and power. Let the 1960s marketing fable die.
Hi guys. You firmly suggest not to remove the spark arrestor from the Akrapovic cause it affects the bottom… Do you suggest the same thing with 250s?? I just bought a 2025 sxf 250 Adamo replica that comes with an Akrapovic muffler and immediately removed that final reduction….and it seems to me that the bike is quite empty down low…. Thank you

This is the morning content I needed.
Nobody cares what you need Jacob.
Dirt bike / off-road magazines take note of this channel. Simply great concise, to the point content with no annoyingly loud music intro...
Keefer is the man! They know who he is 💪

Great review Keefer
Paid $7398 out the door for my 24 kx450.Leaves plenty of room for after market exhaust
We’re ???
Central Vermont cycles it was there last one they had. I asked them to price match and they did it. They originally wanted almost 8,000
@@curtsawchik1480 cool! Thanks.
@@juliomaciel750 Shop around, should not be hard to find for $7k. 25s are about to be out.
Both beautiful pipes.
Eddie’s thumbnail looks sick!
Been waiting for this to help make my decision thanks!
I like the Akrapovic exhausts on my street bikes, but for my dirtbikes, i prefer the Pro Circuit. It sounds much better too...
Keefer you’re the man. Love these vids you’re doing. Maybe test some Luxon clamps next? 😬
@@NickW90 Don’t know if the Luxon guy and I see eye to eye on some things. He has a problem with test riders it seems like.
@@Keeferinctesting haha ya he loves trashing you on vital but would still be a cool test for you to try them some day
The Pro Circuit Slip On is also a better option over stock. Good for the weekend warrior.
The price of these exhausts is getting out of hand. Cost of production of these things is no more than $200. I think the consumers are just flipping the bill for the race teams that use this exhausts for free as they’re sponsored by the brand.
FMF is even better. The FMF full ti pipe or the FMF slip on with stock header is also better than the Pro Circuit.
TI 6 vs FMF 4.1 mega bomb is what I’m interested in!
Good video Keefer, Do you have any more 2024.5 SXF 450 FR Content coming?
Omg I had a 2004 kx450F. And I miss riding so much. But I’m to poor lol and have children. Maybe someday I can again.
Lol no you didn't. 06 was the first year.
Thank you for this... I have your map in my 24 KX450.. Do you still use your map or you using a Vortec still? I have done the FREE MODS, exhaust,and airbox,and Keefer Map.. love the bike
@@tldec I am on a Vortex with these bikes but but currently can use “The CHA” map with these exhausts.
@@Keeferinctesting I'm leaning towards the Pro Circuit exhaust.. also is the twin air mod worth the big price? or just take the back fire screen off the cage?
@@tldec good question
Great video!!!
$1700 for an exhaust system is Ludacris, I’m sure it’s nice but bro. a full system for a 2 stroke is $400.
@@baylonjones3771 True. Some people prefer four strokes though.
Hi mate what’s your view on the hgs pipe
2 things. 1. I saw you doing this yesterday at GH and it's already up on your channel. Amazing. 2. Were you wearing a vest to be hotter for LL prep?
@@moto67e Haha. I was wearing vest for LL prep. 👍🏻
@@Keeferinctesting good idea.
Will I have to re-tune the bike if I add the pro circuit full exhaust? Thanks!
Keefer is the twin air power kit worth the coin vs just running a 3d printed cage with twin air filter?
@@themodifiedlife2774 It does not add any more power. The TA PF kit has better sealing but if you have a 3D printed cage already and had good luck with that, keep it.
have you tried the get sx1 ecu

Back pressure is bad, scavenging is good!
@OtisFlint scavenging only occurs in a 2 stroke. In a 4 stroke you can't flow air past a closed valve.
@@Randy_Cox False. Valve overlap is a thing, and scavenging is what makes volumetric efficiency above 100% physically possible without boost.
@@OtisFlint ever look up valve overlap duration for dirt bikes?
Where to buy the pro circuit exhausts? Everywhere appears backorder only
If you put higher quality packing in the muffler, like those pillow packing rolls, doesn't that fix the problem with the Pro Circuit?
@@ncyrider16 No, sir. It may last a little longer but still won’t be as good as Akra.

@@paoloc.6726 Yea. I leave all my inserts in, in all bikes with the Akra.
@@Keeferinctesting thank you very much! 🤙
Pro circuit sounds good
$6k or $7k? Huh
The KXs are pigs now. At least it saves weight
