As it has in years past, the Husqvarna FC 250 features one of the best engines in the 250 four-stroke motocross bike segment for 2021. It is a little bit smoother throughout the rpm range than the 2021 KTM 250 SX-F, which largely has to do with its airbox receiving less airflow than its orange counterpart. Although the FC 250 comes with an optional ventilated airbox cover, its six slit-shaped vents aren’t as large or as plentiful as the 10 perforations on the 250 SX-F’s. The good news is that you can take your trusty drill and add some holes to the FC 250′s airbox cover to make it run more like the KTM.

Despite its less aggressive nature in comparison to the 250 SX-F on the track, the FC 250 engine makes just about the same amount of power as the KTM along the majority of the rpm range on the dyno. It actually produces more horsepower than the 250 SX-F from 8,800 to 9,800 rpm and a touch less from 11,000 to 11,500 rpm and 11,900 to 12,400 rpm. The 250 SX-F begins to ascend higher on the curve at 12,700 rpm until it makes its peak horsepower of 41.1 at 400 rpm higher than the FC 250. At peak, the 2021 Husqvarna FC 250 cranks out 40.3 hp at 13,300 rpm and the most in-class torque with 19.3 pound-feet at 9,100 rpm.

“Even in the aggressive map 2, the 2021 Husqvarna FC 250′s power delivery is very smooth initially and begs to be opened up. The coolest part about the delivery is that it is so smooth and builds power throughout the rpm, but really comes alive and lets you wind it out.” — Michael Gilbert
