How Much Power Does the 2023 KTM 500 EXC-F Make?

Dyno testing KTM’s 500 dual sport motorcycle for horsepower and torque.

The 500 EXC-F is KTM’s flagship street-legal dirt bike. It’s such a popular model that the Austrian manufacturer even offers a special-edition version of it called the 500 EXC-F Six Days. It’s all-new for 2024, which means the 2023 machine marks the final year of a generation that began in 2020. We look forward to testing the 2024 model, but there’s still work to be done with the 2023 in the form of a dyno test and comprehensive review.

To find out how much horsepower and torque the 2023 KTM 500 EXC-F makes, we strapped it to our in-house dyno. With a Dunlop D404 street tire mounted on its rear wheel, the fuel-injected liquid-cooled SOHC four-stroke 511cc engine spun 40.5 hp at 8,200 rpm and 28.6 lb.-ft. of torque at 7,000 rpm. In terms of peak figures, that’s comparable to the 2023 KTM 250 SX-F for horsepower and 2022 KTM 350 XC-F for torque. How is that power delivered to the ground, both shredding in the dirt and traveling on the pavement to the next trail? Stay tuned to the site to find out when we publish our full test of this iconic street-legal dirt bike.
