Needs 200 with all the bells and whistles to make me buy it tbh. Hopefully there are a lot of eu restrictions in it unlike the previous models

[@_Makanko_]

Love the little engineering bits thrown in by James. The things that amaze/regale people like him are thing I really care to listen about. That's a lovely curve for sure!

[@MadChalet]

I was surprised he wasn't aware of KTM's frame design. I believed the 'squashed' tube is to retain longitudinal rigidity while enabling more lateral flex.

[@_Makanko_]

@@MadChalet I for sure wasn't. I'm not sure how things work at a shop but I doubt they get all the engineering specs on every new bike model. I could be wrong though.

[@deanmsimpson]

​@@MadChalet I believe they did something similar with their MotoGP machine also. But I think they've moved on to a carbon fibre frame now.

[@itsnottheturbo]

More from the jhs guys, always a pleasure seeing them on the channel.

[@firestorm755]

That's a ton of power for a twin. A few years back that power would be wsb level. Here it is, euro 5 or whatever and a warranty. Unbelievable.

[@typischfreddy605]

Jeeeez look at that pipe glow at 04:48

[@flamintasty]

Cos they’re lean as fuck to get the cat hot so that it works properly. That way the EU turds are happy.

[@ps360bros]

yeah ktm is known for super thin piping. my 890 will stock pipe glow bright red after about 1.5 minutes of idling lol.. especially on the right side

[@Jim-hm7fb]

Its not unusual at all. My GSXR 750 will glow the pipes on a warm up at say 4k rpm, never mind full throttle on a dyno.

[@kowalski2334]

That is normal and nothing special tbh

KTM has gotta make a new RC8 with this engine

[@fokjohnpainkiller]

They don't have the balls unfortunately

[@exothermal.sprocket]

With no traction control, no power modes, and a cable throttle? Challenge accepted.

[@popsproductions8547]

The current RC8C is just a lil engine but its an animal. The LC8 in that bike would be Beast. It would shit on panigale.

[@jamsstar2010]

It is a 1.4 though

[@flamintasty]

@@jamsstar2010 Well, 1.35 if you want to be pedantic 😂

[@rafaellastracom6411]

@@jamsstar2010 Sure, it´s a big engine but any way you cut it 176 hp at the wheel is tremendous for the street. That torque curve is as flat as can be with almost 100 lb-ft of torque. Displacement aside, this thing is a beast.

[@cuzimaluzer777]

I wonder where it'll be with the powerparts full system and tune

[@jonomasonILoveU]

Just picked up my brand new 2024 Duke 398.7cc Corner Rocket- blue-, with a few mods attached, "I`m nearly a big boy mummy"!!, I love kTm😁.

[@mbpm6135]

That power and torque curve is absolutely ridiculously beautifully smooth for a big V-twin. What manufacturers can do with 2020's tech despite all the EU emission strangling is true wizardry. KTM has truly earned the reputation of extracting the maximum fun out of a twin cylinder over the other brands.

[@Jones-xx2gc]

What a beast. I love having my bikes set up on a dyno, even my MSX 125. Great video.

[@flamintasty]

I never noticed how wide these are until James pointed it out. It’s almost as wide as a lass from Grimsby.

[@K-so8gx]

James videos are never long enough

[@ericsbuell]

For Mr Holland @6.50 ish "I had a Viva" 🤣My first was the HB followed by an HC, apparently the performance of the HC was much "improved" by the increase in capacity (or swept volume if Mr Holland is reading) from 1159 to 1256....I never noticed this back in 1978 where it struggled to shift us lardy bikers and our "molls" in the depths of a Scottish winter at anything over 60 MPH, just as well, back then the drivers cut-off point was roughly six pints.

[@drdanimalsize]

Absolutely loved my b-king!

[@red.riot.2280]

Wow! Awesome. Now it needs the full Akra.

[@RacerJuan42]

That’s an impressive dynograph! I would speculate that that flattened tube is designed to provide increase chassis stiffness in vertical plane, and more chassis flex in the lateral plane.

[@tubejorrit]

@6:32 its actually 1350cc, previous one was 1301cc so only a 49cc increase.

[@FortyFourTeeth]

I wasn't going to correct James while he was mid-flow 😂

[@cgracing8993]

Currently going through the process of my big bike test! 44 teeth is keeping me going in the meantime loving all of the uploads recently!

[@Markycarandbikestuff]

Good luck, did mine 4 years ago, best thing i ever did.

[@exothermal.sprocket]

So far, tuned on pump gas the thing is making 180 hp and 109 ft-lb in the States (starting value 176/105).

[@shadowred1980]

Great stuff.

[@flamintasty]

I just can’t get over that headlight. Reminds me of a girl from Croydon.

[@flamintasty]

@@markjohnson8352 No, Shaniqua.

[@carado1984]

I have no idea what that means (from the US) but I want to know

[@flamintasty]

@@carado1984 Croydon is a place just south of London. It’s a shithole. The girls there are a special breed. The sort of girls who’ll put out on a first date and don’t really expect to see you again. In America you have Arby’s, and they say women over 30 kind of resemble Arby’s, down below. Well that’s what the headlight reminded me of. A well used girl from Croydon. You know the type, a certain part of their anatomy resembles the predator, and now they want to settle down. Obviously I have had too much social media in my life, and now I compare a headlight to a lady garden.

[@Lumpys_Garage]

First time you twist the throttle you won’t give a crap about the headlight.

[@propheticpig868]

100% reminds me of the Suzuki B-king. Damn , the way you Brits talk is soooo funny. Love it ! 👍 Anyway, the engine is quite the piece of mechanical engineering !!! Can't wait to feel it rev up during fast, hard acceleration. Sublime, no doubt. Like the guy said, the engine revs smooth as an inline 4 cylinder.

[@scott02464]

Every time James is on it absolutely makes my day 😂😂😂

[@nickrider5220]

That's bloody good going on a fully road legal V twin and that spread of torque.....Chopsy's right, that thing is going to be a serial killer with mods 😮 lbft torque = pounds acting at a distance of 1 foot....Imperial version of Nm.....not mN or ftlb..I blame the internet !

[@ninja12lawbreaker]

Another engineering eye openner from James, I suspect the oval tubes as he says is to increase rigidity on the vertical plane and allow flex in the lateral plane. Like Rossi felt the first time he rode the Yamaha R1M and extended the engine bracing and made them narrower to allow flex in the frame under power.

[@mrspoonandfork]

What more could you want on a moist Thursday morning than a saucy little JTS Dyno vid! Thanks guys!

[@C.A.MARSUPIAL-ys6tl]

Just a excellent video. Hi from Brisbane Australia. KTM owner 👍

[@dankorolyk5917]

Brilliant job by James as usual

[@AST4EVER]

wondering how much this would make breathing freely with a full system flashed ecu 👀 considering it's restricted too with latest and greatest barriers.

[@Oggyzd]

Incredible stuff! Dyno curve looks similar to big Ducati twins (1199 / 1299).

[@shivhappens9200]

Except the ktm has low end torque.

[@enzorum2560]

i noticed as he was looking at the footpegs near the end, that it seems they've made it so you can increase the height of the footpegs from the frame too!

[@vytas5584]

Wow spotted the same glass kit that’s on my SV650! (The orange one) in Australia. Awesome!

[@scottieray]

I owned a B-King...absolutely loved it.

[@gnarshread]

Hell yes! Looks like KTM is killing it with this one.

[@chriskingston6054]

My gen 3 makes the same with full akrapovic. Wonder if these can push 200rwhp

[@phantomrider22]

Riding a KTM tricks my brain into thinking it's a straight 4 because of how smooth it is. I had a hard time remembering to keep the revs lower..

[@JNAMOTORSPORTS]

You like coming in through the back door “giggles”

[@davroshalfbeard8368]

Not a fan of twins but ktm have done a great job on that bad boy .hope to see the jickster soon cheers.

[@flamintasty]

Epic engine and chassis.

[@xorbe2]

100whp at 6k rpms, it's a lot for a road bike. You'll be short shifting at 3k all the time like a cruiser.

[@CCitis]

No where on legal roads you can use that power.

[@magnumwelders8545]

How many Ks on it, she could probably loosen up a bit and shed another couple of ponies yet??

[@sn00pgreen]

to be honest everytime I play around with my 890r I'm impressed with it's design and build

[@popsproductions8547]

Bt put it on the dyno n got 175 so this must be already tuned , yeah?

[@HybridSonaHaver]

Lordy that’s rowdy out of box. cannot wait to see what tunes and intakes do em like the 1290s and 990s before. 👀

[@ehiggins7476]

For bragging rights yes tune them to get more power but from a practical standpoint I do think it needs more power.

[@hexagonosaurus5848]

​@@ehiggins7476 then buy an mt07 and shut up. No naked bike "needs" more than 100hp.

[@ehiggins7476]

@@hexagonosaurus5848 typo, I meant to write I don’t think it needs more than 175 wheel HP. For track use maybe but for street I’d be a bragging number not a usable one

[@james5553]

It does make quite a big difference to the drivability on the 1290 that I have. The tune that came with the full akra system made it feel like a lot more responsive - the way I describe it, is all the torque of a twin low down and then you still get the rush of an IL4 at the top. I tested the s1000rr and Aprilia, but this was the only bike that left me giggling. You do not need it on the road, but it does make it a lot of fun when you get the chance to open it up. @@ehiggins7476

[@796andy2]

just got smcr , very impressed. my speed triples been gathering dust

[@tswc42]

Always happy to see James in a video.

[@ozbiker5311]

I think you can see the cam shift a bit in the torque drop at about 5200 - to about 5400 rpm before it climbs slowly again till about 6500 that climbs again till about 8200 and starts to drop off imagine what it would be like if you could tune out the dip from 87 to 92 - 93.7 in curve on the torque 🤪🤪 I wonder if you could tune it out, 🤔 maybe with the full system as you said when riding that one one the test!! it felt like it went harder maybe its torque curve was like that on that bike 🤔🤔
