Hello fellow mx'ers,

a question: studying the various tests of the Husqvarna fc450 2018/2019 i see different horsepower numbers.
Some claim 58 hp (mxa/dirt bike mag dyno runs), some say even 63 hp.

Who's to believe?

Every dyno will get a different result depending on how they set it up.

Every dyno reads slightly different. Weather/altitude/motor temp (was it the first dyno pull, or the 4th?)/.etc also have a large effect on HP. It’s nearly impossible to make an apples to apples comparison unless the dyno runs are made back to back, same dyno, same day.

Believe both.

63hp is from Husqvarna’s website and is horsepower at the engine.

56-58hp dyno tests are showing horsepower at the rear wheel.

A dyno is a tool used for tuning. Nothing else.

Hm, definitely a step up in torque
