So every year we get pretty detailed break downs of what each manufacturer has updated on their bike and what those changes will do to add hp. We saw with the yamaha when they changed the engine layout how they have the ram air, wrap around exhaust ...etc. Then with the honda we have full engine pictures like on the new 250 showing the downdraft intake, twin exhausts, twin cams, two intake/exhaust ports. I feel like since KTM hasn't really gone in any crazy new direction that we haven't gotten as detailed explanations of what is going on inside these engines to create so much hp. They use the old school dohc, standard exhaust/intake layouts on the 250 and sohc on the 450. How are they making so much more horsepower than everybody else while using the old school engine layouts. The new honda 250 is making way less hp and tq than every single other bike like 5 less the whole power curve until 10k rpm then it revs higher than all of them and pulls power longer.
The KTM/Husky on both their 250's and 450's are making way more horsepower than all other brands and they use the old school layouts with no downdraft, ram air, twin exhaust...none of that. They use the old school engine layouts like the Suzuki and Kawi. What is going on inside these engines to make them so much more powerful? I feel like it has not been explained as much in detail as the others so I really don't understand what their doing in there to gain all this hp. Can someone help me out and let me know what they're doing? KTM, Husky, Kawi, and Suzuki are all essentially using the same engine layouts apart from the Kawi/Suzuki having DOHC on their 450 models. Anyone? This has interested me for a while and I was very surprised when looking at the dyno's of the new 250s how with all the changes how much less hp the honda makes than every other bike until 10k rpm with the downdraft and twin exhausts. The KTM/Husky have used the same engine layouts the whole time along with what all of the other bikes all had at one point but yet they make by far the most hp, I don't get what their doing to get this and why other brands can't keep up although they have all had this same engine layout at one point or another or still do. Thanks.
