TESTED: 2023 KTM 250, 350 & 450SX-F MODELS

Brakes, wheel, voltage regulator, throttle body, start relay, ECU, handlebars and grips – these are the only components that KTM’s 2023-model MX bikes share with their 2022 predecessors. Which means this new range absolutely qualifies for its “new-generation” tag.

But how have all those component and design changes translated into on-track performance? Well, we’ve already dish up our specific feedback on KTM’s 2023 two-stroke MXers. So, it’s now time to do the same with the four-stroke models – the 2023 250SX-F, 350SX-F and 450 SX-F – again with the help of a KTM connoisseur, Mike Sleeter, who for 15 years was employed full-time to develop KTM’s production bikes in the USA before recently moving to Oz.
