The revised engine settings are noticeable and an improvement in overall power. The good news is that it still has a fairly smooth and easy-to-ride powerband for a 450cc competition model. Changing from map 1 to map 2 is noticeable, but on the day’s track conditions, they were not as big of a difference as expected. Both had good initial throttle response and smooth power delivery, with map 2 simply having more grunt from the midrange to the top-end. For the most part, traction was not an issue throughout the day and a little extra torque was welcomed, so map 2 was preferred by test riders.
The transmission on the Husqvarna works well with reasonable spacing between gears. For 2020, Husqvarna went up one tooth on the rear sprocket for a final drive ratio of 13:49. Second gear was very usable in tighter corners and ran out quite far into straightaways. The shorter straights between corners could also be ridden without upshifting. For the longer straights, third worked very well and had good acceleration for all of the obstacles. Fourth was rarely used as the Husqvarna’s engine revs plenty far in third. The Magura hydraulic clutch is smooth and works flawlessly, being very consistent and easy to modulate. The smooth powerband also minimizes the amount of required clutch input.
