200 HP TOP SECRET 143 CI V TWIN 2025 ROAD GLIDE & 2024 HARLEY-DAVIDSON CVO ST 121 

Oooo liquid cooling. Took'em what, 30 years after the metrics, to get to liquid cooling? Better late than never.

You guys are on top of it . All great products with the build

Great video man! I enjoyed it BIG TIME Thanks for sharing 👊

I think the 2024 RG CVO ST 25th anniversary is the holy Grail for the 24 model year! Awesome looking bike!

My 01 929RR made 128 back in the day. This Hog is gonna move!!!! 😳😳👍👍👍

Matt is the Man. He did my 2022 Limited CVO 💪🏽💪🏽

The incorporated the radiator awesomely.just a killer bike but the money for it and upgrades is insane....

Gorgeous looking bike. Happy 4th of July! Ken and your family and your kitty cats and your team

Matt is definitely the man when it comes to all of the performance engine mods for Harley Davidsons. Super Talented, a wealth of knowledge, aims to please the customer, and humble. Nobody, as a customer, could possibly want more than what Matt has to offer. ML&R.

What a curve 💪….that thing must boogie

Harley Davidson is the Apple Iphone of bikes, they give you new tech one bit at a time to keep you buying the latest and greatest.

Wow! I'll bet it's a Beast!!!

It's nice to know my CVO ST has even more potential...

oh my God that torque curve is amazing

The FXR dude, cool...

I remember when I owned an Iron head, the oil pan would literally roast your nuts, I think if Harley Davidson made one of these engines completely liquid cooled, you would not only see an improvement with reliability but massive performance gains.

No restrictions!🤘

I love my 1974 BMW R90 65 HP! Gets me where I’m going with plenty of smiles.

Dreamy! 🤙

Harleys are like David hasselhoff...... Cool in yhe 80s.....but☝️....love your videos Ken, keep em coming please

oh shit its matt!! dude built my 2022 ST! that mans the goat

Rear cylinder receives the coolant 1st. He described it in reverse.

Such a badass bike! And great power, with a stage 2 cam it should be able to make close to 150hp

Very cool! Happy Fourth of July everybody! It's kind of weird to hear Ken talking about Brock's and BST wheels and ceramic bearings and stuff!!! It's like all the stuff I hear on some of my "superbike" channels. Very cool indeed. Up next, all of Kaplans vintage restorations are now going to come with a battery tender lead, gold chain, ethanol free fuel AND ceramic wheel bearings!!! Ha! Yay!! 🤣🇺🇸🇺🇸🦅🦅

This guy is great - I learned a ton about hd performance. I wonder if the VVT on the 121 is leaving any hp on the table.

"Curly inc" in burns harbor Indiana has built a bike with this engine in it. Lots and lots and lots of money.

I bet the chop on that thing is nuts 🥜!

Impressive knowledge of the V-twin Harley motor. I'll bet it rips

I bought a new CVO st and it's better than I expected.

So your Harley-Davidson road, glide got the 121 liquid cool. That must mean it doesn't run hot. What an amazing road! Glide not like the other Harleys like mine to 2011. She runs hot. What a great bike! Congratulations, Ken is that pig with the flags airbrushed? That's a really good test on the diner wow! Stage 4 131 wow! Wow! The sky you found is the next Grand wizard Ken, that motorcycle with the 131 stage 5 150 horsepower I'm sorry Ken but you made me say it rip the foundations out of the house. That bike is intense

The Indian challenger is a very reliable liquid cool motor . Is this going to be as reliable ?

my 131 is making 160 hp 155 torque she is a bad mofo great video cant wait to visit your bike museum one of these days.

I'll stick with my '89 Sportster that I had since 1989 and was rebuilt in 1992. It works just fine. I have a '91 Sportster as backup now,

Awesome video but your guy gave wrong info. Liquid cooled heads 2014 and the cooling flow goes rear cylinder first then front cylinder.

Curious if I want to build a bike like this 143" with all the bells and whistles what's the price tag I'm looking to have you build it for me?

Bad ass ,im not a big harley guy but im impressed with that 143

Rock on

Does the new Road Glide CVO ST feel faster than the Pan America? Does it handle the twisties better?

☝🏼🔥

Wouldn’t it make more sense to have coolant flow through the rear head first? Like why send hot coolant to the head that gets less air second?

Gotti ❤️ it

🐝🏁 Video 👍

Rock On

Only took harley since the 80s to catch up with the entire industry

When will Captain America launch that Hog!!!! #toecutter

Well, awesome bike for sure👍 but the price tag to build one of these bikes for $15,000 plus on top of with the bike cost it’s a lot of money🤔

Happy 4th everyone at Kaplan Cycles 🇺🇸🚲💯

I want one 😂

Monster garage in ct

What was done to the cvo st to get those number????

👍

You guys doing anything with the 121 vvt motors

You have to turbo that

If you combine a Harley Davidson engine with a Toyota CVT transmission, it will create the best product!

Did Harley beef up the primary drive/final drive? Always was the weak point.

I'm still super proud of my GS 😎 123 horsepower with only 1200 cc's... Smooth, quiet, efficient... Five engine maps... On the fly push button suspension settings, For solo riding, passengers or extra gear... Less than half price😂 final stage global domination machine 🪄 I know. I know even Ken Kaplan is jealous😅

This bike should come with ohlins for that price tag. I get showa is better then stock but their no ohlins. Beautiful bike tho

Well, don't see fossil fuel going anywhere any time soon!👊🏻😂

So you buy it new and then have to get rid of all H-D parts just to make 120 HP? Doesn’t seem financially exciting to me.. 😢

Thundermax

It wont be reliable just like the rest of HD bikes.

Very impressive Harleys are the most attractive looking motorcycles ever plus the sound is amazing along with the ride, Everything else looks like a pile of crap next to a Harley even a Indian does not do it for most people.

🫡🇺🇸❣️

God knows I can break itt

The liquid cooling basically gives the new 121ci engine the power increases and potential over the 131ci engine. It's not rocket science.

I guess I don't understand why people want to put all that money and horsepower in a Touring bike

The more work you do to the engine the more unreliable the engine becomes! I can see if your racing the bike but for regular everyday ride stock is plenty of power with more reliability. All this becomes talk look how much I got in my bike look what I did to it look how much horsepower and torque it has yippee yay I’m broke and broken down. Would not be able to go to higher compression without liquid cooling it. They’re at their limits

Don't care for the Composit / plastic oil pan / drain plugs on the 121ST

Woke Harley Davidson is dead to me now... 💥

Carbon fiber wheels on a Harley ???? Yeah let’s save 5 lbs on a bike that already weighs as much as 68 VW beetle 😂😂

California ruins everything

Mention the issues with hilding moisture , milkshake oil?

Happy Independence Day! The Harley nay sayers just don't get it and never will.🤏🤣👏👏👏

Very. Nice fantastic bike!!!!!! Professional 🇳🇱👏🫡
