So I took my Vitpilen in for a dyno run today; at the local shop in Horsham – Horsham Harley Davidson / KTM / Honda.
*** This dyno was done with the Leo Vince de-cat pipe and slip on. I had initially planned today to be a stock pipe/cat test but I couldn’t resist putting the new pipes on as they showed up early in the mail on Monday.
I was told over the phone by the dyno guy (Joel) that I’d be allowed in to watch. I got there and the owner said ‘no way’. Health and safety and the like. I was a bit disappointed but I still booked it in. I gave my phone to the guys and they at least captured a bit of footage of the run :
Here is the power/torque graph. There is a blank spot in the middle, Joel said he did a few runs and still had the problem. There was an issue with the electrical signal from their sensor wire at certain RPM … apparently. I asked if he had this problem with any other bikes, and he said yes. Oh well. I joked that I might get a free dyno run now, since the graph isn’t complete.
I’m not sure why the dynograph doesn’t show bike RPM higher than 7 – 7.5k . . . he said he ran the bike out to about 9000 RPM (which you can see in the video if you zoom in on the screen).
I had requested AFR’s, but was told it wasn’t possible because the grill over the end of the LV10 slip on prevented their sensor going down inside the pipe. The mesh end cap was riveted on to the Leo Vince, so I couldn’t easily remove it.
They seemed to think that 65 horses at the wheel was about right for the rated power of the engine. Torque figures above are in ft-pounds.
Riding the bike, I am not sure I can feel the difference between cat+stock pipe and the Leo Vince pipes. The bike certainly sounds more awesome, heh.
The bike still does 200 easy enough.
Do you experienced 690/701 guys have any thoughts for a noob like me? I’m only just learning about dyno tests and all that. I need recommendations on an improved air filter – there are a bunch available : K&N vs DNA etc?
Should I chuck the stock pipe & cat back on and go in for another test? Should I try the bike with the stock pipe but with no cat? Once I’ve improved the air filter to an aftermarket model, maybe I should get this :https://vitpilenforum.com/product/amp-performance-ecu-vitpilen-701-by-coober/ to boost performance?
So much to do, good times 🙂November 28, 2018 at 5:52 pm #2847
Nice. Get the coober, dyno and dial it in, and report back so I can see if it’s worth it 😉November 28, 2018 at 8:08 pm #2851DAP831Participant
Too bad you couldn’t get an AFR reading, I am really curious to see what it is. I suspect it is pretty lean. I have the decat and pre-ordered the silencer on RevZilla. I am not sure it makes sense to install it until Dynojet has a power commander available for it. I would want to make the fuel/air ratio richer than what the stock ECU is putting out to really take advantage of the increased airflow, although losing all those pounds will be nice.January 12, 2019 at 9:15 pm #3164Rob of SwedenParticipant
Leo has dynocharts for all combinations.
Stock muffler and decat is the best and very similar to stock. Maybe little more tourqe at 5000rpm.
Worst is Leo slipon with decat.
I think you have to remap the failing.August 24, 2019 at 12:10 pm #12178
Hi Tori I’m about an hour down the road in Ararat and also have a vitpilen 701 that I’m building as a race bike,out of the box mine was 69hp on the same brand dyno have just ordered a pc5 to give it a much deserved tuneAugust 24, 2019 at 12:11 pm #12179September 4, 2019 at 2:22 pm #12344
So kev, 70 hp dyno run, that’s with stock pipes and the decat fitted or do you have a different exhaust config? Husky claims stock bike runs 75 hp, cycleworld put it at 71hp @ 8500rmp.
Very interested in your results with a PCV. Reports from other threads here say there isn’t a map for the vit 701 yet and that there isn’t a connector for our bike. I believe someone mentioned they tried to order the unit for a 701 SM, which has the same engine and it was not compatible.September 4, 2019 at 10:06 pm #12349
70hp stock,my pc5 has landed here in Australia to suit a vitpilen 701 im the first to have ordered one, they claim 75hp yes so 70hp stock on my dyno is about right. Have put a cat delete in it now so will tune it to suitSeptember 5, 2019 at 5:45 am #12357
Well you are right sir. I went on the site and they are finally offering a vit 701 product. Assume you just got the PCV (as opposed to with the auto tune mod)?
Very interested in your PCV results as I have the Leo decat installed and am sure it’s running lean. Would obviously like some more hp. Are you going to get afr’s charted with your tune?September 5, 2019 at 9:58 am #12365
I’ll be tuning it mate (10plus years of dyno tuning experience it’s what I do for a job)September 5, 2019 at 12:05 pm #12369ToriParticipant
Sorry I didn’t see this message until recently. Yep, I’m not far away – we should catch up! I have had the Vitpilen 701 parked up for a few months – getting back to Victoria was a bit depressing after a 2 week and 4000km blast around Tasmania . . . oh my.
Anyway, I see you have some expertise in Dynotuning. I took mine in to Wimmera Motorcycle Co (mentioned in first post) and never got a proper run (their machine was set up for Harleys . . . /sigh and didn’t catch RPM in the upper bracket).
Per mods – I have a Coober ECU, DNA air filter, and a Leo Vince race pipe. I’ve removed the cat. I haven’t opened up the air-box cover, but perhaps I should. I see Coober have drilled 3 x holes (probably 1 inch diameter?) in the airbox cover to allow the bike to breath better.
I nearly got the 701 out the other day, but I also have a 690 Enduro R (2019) which I’ve been fanging around local dirt and tar over the cooler months. I need some ‘tard wheels for the Kato – it’d be hilarious on the ride to Halls Gap and back (I’m near Wartook).
I’ve got 11000km on the Vitpilen, but most of that was done in the first 6 months of ownership. I’ve had the bike about 11 months. It’s mint and begs me to ride it. Having another Vitpilen owner down the road is very motivating.
Anyway let me know if you’d like to meet up and perhaps I could benefit a bit from your expertise.
Thanks for reaching out 🙂

Here’s how mines looking at the moment,just put a Nitron Race Shock in it upgraded the front end while I was at it as well.Took it to Mac Park in the weekend to get some race miles on it,I usually race 600 supersport and superbike so not a stranger to the track.Im really happy with it and I think I’m on to a good thing,the classes it will run in are Supermono,F3,limited & BEARS F3.Will keep you posted with any other stuff I do to it
Kev212September 5, 2019 at 2:32 pm #12373
Very nice. How is the Nitron treating you around town? I actually am very happy with stock handling, tho have never tracked this one
When ate are you going to put on the PCV?September 5, 2019 at 8:17 pm #12382
This is a race bike only hence why I’ve put the Nitron on it.September 11, 2019 at 1:33 am #12472
Ok @kev212, another question for you. What year is your 701?
The product page at dynojet says for 2019 model. I reached out to their support and they said that’s the bike they did their tests on so they can’t confirm 2018 compatibility. I don’t think there were any changes to engine or electronics (or anything else) between 2018 and 2019 but I don’t know for sure…
