We dropped in to see James at JHS Racing to find out how many horses the 2024 KTM Super Duke R churned out... Apex66 - www.apex66.co.uk/competitions/ 44T MERCH - shop.44teeth.com/
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!
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.
@@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.
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.
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.
@@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.
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.
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.
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!
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.
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 !
@@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.
@@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
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
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 🤔🤔
wondering how much this would make breathing freely with a full system flashed ecu 👀 considering it's restricted too with latest and greatest barriers.
You know I despise how it looks and sounds, but i dont hate that curve shame It'll blow a rod on the track lol knowing my luck with the orange machines.
