How Much Power Does The 2019 KTM 450 SX-F Make?

The 2019 KTM 450 SX-F motocross bike is raced by the Red Bull KTM Factory Racing team of Marvin Musquin and Cooper Webb. We put KTM’s flagship motocross bike on our in-house Dynojet dynamometer where it produced 50.79 hp at 9,320 rpm and 32.55 pound-feet of torque at 6,800 rpm.

Is it 250i dyno?

Thanks 👍

Interesting, my 2017 put down 55 before tuning on a Dyno Jet. 60 with custom tune

[@Wreckhouse69]

Bruh my stock 2015 rmz makes 51.8hp and that’s the average over 2 dif dynos 4 tests. and yes it’s bone stock. Y’all really need to get this whole bike bias under control . Have people telling me “ktm 450 goes 120” no it goes about 90 I’ve ridden 2 dif years of it. “Ktm 450 has 10 more hp than rmz rmz sucks” uhm no. No stock 450 ktm has even dynod even close to that ?…. “Rmz is too slow “ bruh my rmz gets better hp and torque down low than any of your fancy electric start bikes. Just my two cents Suzuki is seriously over hated on for “lack of changes” ok but changing a bike just to make it equal to or worse than year before isn’t something we should be holding companies to?

Thank's for post. 🇧🇷

You're welcome, Marcos.

[@dr.hugog.hackenbush9443]

This makes 1 less hp than my '83 YZ490.

[@kaisuhina8024]

Crank vs rwhp

[@dr.hugog.hackenbush9443]

RWHP. All of my bikes have been tested on a DynoJet dynamometer. My YZ also has a microbalanced crank, head mod, clean--up porting, dual-stage reeds and a vintage PC pipe & silencer. It runs the way it was supposed to, instead of what it was.

[@kaisuhina8024]

@@dr.hugog.hackenbush9443 dynojet dyno also showed 59 horsepower for stock ktm exc 500, witch in reality has lower power than sx-f 450. Every dyno shows littlebit different power, they are good for tuning for max hp, but not for real accurate power measure.

This KTM SX-F 450 is the American Version with 5 Gears, the European Version has only 4 Gears.

[@TheMaster5150]

What are the mxgp's running 4 or 5 gears?

FI or Carb?

All the current MX bikes are FI, this one included.
