The KTM 450 SX-F is one of my favorite bikes to ride and race. In stock form, the 2022 450 SX-F has an easier to ride smooth roll-on power than other 450s in its class, and that lets the rider get on the throttle sooner through corners. The stock suspension is decent but needs some better lean angle front-end traction and more hold-up on the shock. Not all Garage Builds need to be extravagant, so I thought this month we’d build a machine strictly on what the bike needs in order to make it even more fun to ride and race.
