FIRST DYNO Runs: Triumph TF250X

Our first dyno runs on the all new Triumph TF250X
Lets see just how much power the bike makes and if the test reports are accurate.

[@mxengineer1]

Thanks for the dyno runs and comparisons! Looks like Triumph did well for their first 250F and most likely went a little conservative to make sure durability was strong out of the box. These bikes look better in person with excellent build quality appearance. I wonder if they change much for the 2025 TF250X?

Great video as always.

[@evanwilliams2602]

Id like to see you do some dyno testing on a 300 enduro models! 👍🏻

[@moto3463]

Sweet

There was a Triumph dealer linked with a popular KZbin motocrosser whos a really cool guy. However the dealer told him it makes 51 Horsepower and I immediately said "Absolutely not". I got so much shit from people. Ive spent some time around dynos and modern motocross bikes and have not seen a stock 250f make 50 ever before. My Dyno had the Triumph @ 42.8 HP / 20.4 TQ

[@HPRaceDevelopment]

Id say your dyno damn right to accurate. the bike we had did well and had a decent fuel in it - by all accounts with some mapping the bike will do what ours showed and most people showing 42 ish stock. 51 is world class

[@s-vr2hu6si7s]

cool, didn't know they made a dirt bike

[@fugginrambo]

Does the race fuel help with the nasty bog in the low RPM when snapping the throttle?

[@HPRaceDevelopment]

@@fugginrambo Some do - but do you actually do that on track - or just on stand and in the pits trying to do it?

[@fugginrambo]

@@HPRaceDevelopment it was just the triumph 250 we had issues, even got a new stock ECU and it still had issues. It was for the little brother of a pro hill climber and the kid is stinky fast. Never had that issue before and yes it while he was riding.

[@charlesclapper8982]

Wich one has more bottom end

[@adriangalvez5104]

Whats funny is that everyone thought it was a copy and paste of a ktm engine😂

[@HPRaceDevelopment]

It is...of the 16-22 generation which performs a heck of a lot like the triumph.

[@MrKips1]

Old ktm engine, warmed over. New ktm power comparisons, please.

[@HPRaceDevelopment]

@@MrKips1 It is compared to a new ktm

[@adriangalvez5104]

​@@HPRaceDevelopment i meant like literally a straight copy of a ktm 250f engine 😂

[@HPRaceDevelopment]

@@adriangalvez5104 its pretty much a straight clone of a ktm. They have a few changes such as a twin compression ring piston which is bad generally for power - and its head is like newer ktm engine port but on older ktm engine design.

[@befree322]

Have u got many 250f over 50 rear hp

[@HPRaceDevelopment]

@@befree322 a few, not many. Have dyno some “good” bikes from a lot of places, 50 is a big number!

[@mxracingunlimitedltd7784]

looks more like a ktm to me... idk. Looks nice though!

[@311hitwall]

no adjustments needed for race fuel?

[@HPRaceDevelopment]

What race fuel.

[@311hitwall]

@@HPRaceDevelopment You said vp t4 and the other brand is race fuel??

[@kasperkytölä]

Would cr250 1992-2001 make good power with tuning? Im thinking of getting it built for supermoto but is it worth it? how does it compare to 2005-2007 in bench

[@HPRaceDevelopment]

Not bad but the newer ones make a lot more

[@franzv3172]

Do you have to retune with the different fuels or can it’s computer make the adjustments?

[@HPRaceDevelopment]

No mx bike auto adjusts. Luckily the stock tune up worked well with these fuels. Selecting race fuels for many people is about selecting a fuel that works well with the stock ecu tune.

[@franzv3172]

@@HPRaceDevelopment good to know, thank you! Have you experimented with 100 LL ave gas? Asking because that’s available to me at a very affordable price. ( 22’ 350 xcf )

[@motocross402]

@@franzv3172I’d be interested in your opinion on 100LL for both 2T and 4T. It’s super affordable and readily available.

@@motocross402 terrible 4 stroke fuel.

[@JakeCroniser]

Hey why would my 2000 cr250r be acting like it completely sucks the bowl dry after half throttle but if I hold it at a quarter throttle it will scream and all it had done to it is a full fmf and phat head on it running c14

[@HPRaceDevelopment]

sounds like you are mis disgnosing the issues

[@take5th]

I’ve heard it is relatively mild, broad powerband. Haven’;t heard squat about power hype.

[@HPRaceDevelopment]

@@take5th Hmm triumph dealers claiming big numbers and hyping it up. media outlets all said it has “more bottom” than ktm and was hybrid of ktm and yamaha

[@take5th]

@@HPRaceDevelopment ok. I saw a couple guys ride, on youtube mind you, and say it was more progressive and broad than the competition, preferred low revs. i certainly dont know.

[@HPRaceDevelopment]

@@take5th Does our dyno chart show power focussed at lower ranges than the ktm? Where does our chart show the highest value of power on the triumph? As far as I can see - its not stronger than the ktm on any point of low end and peaks right near the limiter. So maybe the reviewers need a little more accurate butt dyno…

[@743S]

Hanno copiato bene😅

[@OG_aaronlee]

you should do a 24 kx450 stock/slip on and airbox mods

[@HPRaceDevelopment]

I assume you own a kx450. Find someone with that bike, and those parts in the tx area who is open to doing it and I will.
