It sounds like Husaberg didn't really do much to this bike. I guess it's better than nothing, but with such a good handling bike they just need to come out with a full mx bike and let consumers choose how they want to do the cross-over. From the enduro side with the FE or the moto side with the FX.I've come close to picking up a Berg several times but the asking price is just too steep for what comes down to being a "toy". I must admit that this one looks like a lot of fun though, maybe I better pick up a lottery ticket. By the way that track in the video looks fantastic! I would love to turn a few laps out there.bike is really pretty stock. I do all of my own wrenching. I have upgraded the forks on my FE 450 to the closed-chamber models that will be on the new FX. I do all my own valving and run .48 springs, KRW Cycles helps me with the shock set up and I use the 7.6 spring. The Akrapovic titanium slip-on muffler from Hard Parts catalog gives a little extra power over stock. Other than that, I just use a few personal preference things like a tall seat, the KTM PHDS isolation bar mounts and a floating front brake rotor matched with EBC “Extreme Pro” brake pads.” 
Nick got his first ride on the new models at the KTM/Husaberg Dealer meeting at Red Bud, Michigan and here is his riding impression for the FX450: Things I knew to focus on were handling via new 22mm triple clamp and power delivery through the new FX gearbox. Right out of the gate on the grass track I noticed how the bike's first gear was taller. The FE 450's first gear is so low it is usable only in the nasty stuff and normally only from a dead stop. The FX 450's cog spacing allowed for more forgiveness on gear selection and to keep the rpm range you want without stabbing the clutch. Along with the sweet six-speed gearbox, the motor has been retuned via the fuel injection mapping. The FX has noticeably more midrange punch, despite the stock silencer. This is due to richer mixture thanks to the closed-course designation of the FX. The motor retains its smooth seamless power delivery, pulling stronger when the revs climb. Handling on the FX with the 22mm offset triple clamp, designed for optimal flex, was quite good. The bike had a more settled feel at speed yet would follow ruts on the Red Bud moto track better than any other bike I tried. The bike resists knifing-in and over-steering, yet feels precise enough to let rider input drive the bike anywhere. Cornering is still “Husa-light” as the bike will throw from side to side in tighter situations like a much smaller bike may feel. Suspension is much firmer with increased bottoming resistance over the FE models. It handled all the jumps our grass track had without problem. Overall the feel is both stable and agile
