Ktm 950/990 Bhp?

In the world of marketing seem there’s lie, damn lies and statistics. According to my car manual my 2.3 cc motor is generating just under 200bhp, while I know of a rolling road for cars I know for a fact that there is no way 200 horses at the back wheels.
I have read that the KTM 950 Adv and SM produce 96 and 97bhp respectively and one article that the 990 chucks out 114bhp. I saw a guy on youtube stating his 950 Adv produces 90bhp..
I own an 950SE-R and would say it feels about 80-85bhp at the back wheel, I’ve tried searching this. Has anyone done a dyno test on the 950/990? Or is there already a post?
Nothing to do with this thread but at my KTM dealer last week, seems there’s a rumour they are going to make an Adventure with 1190 engine out of the RC8.
Charlie.

I bet the 85 is the most accurate number from above. 85 rwhp.

I'd like to dyno my bike for fun just to see the look on the dyno operator's face. It feels like it is more than 85 but I know better .

I overheard a Power Ranger stating his Yam R1 was giving him 190 horses at the back wheel, whos to blame? Even Yams site states 139KW, thats 186bhp. I wanted to explain thats probable at the crank on a test bench lean intercooled air, no filters, no gearbox and sucking exhaust etc. Then I thought Id probably have to explaining to him what the crank is, umm keep it shut the probable the better option.

Last test I remember reading in a UK mag (BIKE I think) tested the 990 in the high 80's. The 950 tests I've read were getting low to mid 90's at the rear wheel.
I had a VFR800 (about 95 rw bhp) a few years ago and the acceleration feels pretty similar upto about 100 where the wind drag slows down the KTM.

Here are charts from the KTM UK site from a 950 SM (owned by "Dutch"). Bike has a full Akra system on it. He was just playing with jetting changes:





Figures are SAE (about 2% under DIN numbers IIRC). Chris later found his dyno was under-reading by 5%.

Impressive figures, KTM site states 69fpt and 96bhp as standard. I would say the exhaust system and right set up would give him about 5% + 5% for the lower reading. That’s a guestomate about 10% off KTM’s figures which would roughly give you 86.4 bhp as standard???

Nice one Garry.

and I quote

From Rider Magazine, November 2007.
"When we took it (2007 990 Adventure) to the dyno over at Borla Performance, we found that things had gone in the other direction. The 950 Adventure we tested in our February 2005 issue spun the drum to the tune of 86.7 HP at 8,000 rpm, and 61.3 lb-ft of torque at 6300 rpm. The figures on the new 990 were 84.0 horses at 7,600, and 59.8 lb-ft at 7,200 rpm, drops of around 2.5 to 3.5 percent. Our best guess is that the power drop was caused by the fuel injection glitches, as KTM's press person said the exhaust system as essentially the same. Perhaps it's due to more stringent emissions requirements. Who cares- the bike is great fun to ride!" end quote.

The fuel injection glitch you ask? Let me quote again.
"Our test bike had a glitch in its fuel delivery system; a rhythmic jerking and hunting was evident at stead state, low speed riding at around 3,000 to 4,500 rpm. The situation became especially problematic on bumpy roads as the fuel system seemed to cycle on/off abruptly over the bumps-" end quote.

The last thing I read before I ordered mine!! It's an 84 HP dirt bike, what could possibly be more fun that that, oh wait a 100 HP dirt bike. What's that you ask? Yes I did order Akra's for mine

Neighbor builds bike race engines and just got a dyno at his shop so I will know soon exactly what mine is putting down.

I remember when I test road a 990 Adventure it felt less lively compared to the 950 SE-R and SM. I put it down due to a flatter torque curve due to fuel injection and the slightly heavier bike!
True thought!! Seems if you want the high 90s bhps advertised, you need to spend another thousand on top of list price!!!!

Cool, wish I knew someone with a dyno. Look forward to seeing your results.

1 PS = 75 kpm/s = 0.73549875 kW = 0.9863201652997627 hp

So 103bhp, still very impressive!!! And 141mph!!!

That's not much torque, I was expecting more from the KTM twins, hard to find good info on it too last time I was looking. No wonder why the orange twins don't do it for me
