A special-edition MC Commute review of KTM’s 2021 450 SMR supermoto.

By Adam Waheed / motorcyclistonline.com

After a seven-year hiatus from KTM’s North American motorcycle lineup, the new and improved 2021 450 SMR ($11,299) returns the Austrian bike manufacturer to the 450cc supermoto class. Based off the ’21 450 SX-F motocross bike, the 450 SMR swaps its moto hardware for a purpose-built and competition-specification road setup.

We have published extensive reports on the Orange Brigade’s latest race-ready weapon in the 2021 KTM 450 SMR Supermoto First Look Preview and 2021 KTM 450 SMR Supermoto First Ride Review articles. This review discusses what it’s like to operate behind the Neken handlebar at Southern California’s eight-turn, 0.5-mile Apex Raceway go-kart circuit. Tune in and see what it’s like to ride in this special-editionMC Commute.
