10 Things
2020 Husqvarna FC450
It’s no secret that a Husqvarna was one of my favorite machines to ride in 2019. I liked it so much I went and purchased a Rockstar Edition and rode the crap out of it. I recently got my hands on the new 2020 Husqvarna FC450 and jotted down some initial thoughts for you all to go over just in case you wanted to know how it compared to the 2019 version. I will say that there are only a few updates to the 2020 model, but that doesn’t mean it can’t feel drastically different on the track. Here are ten important things I feel you all should know about the 2020 Husqvarna FC450.
WP XACT Suspension: Don’t let the name fool you. WP just did some re-branding and is now using the XACT name for 2020 WP suspension. This is NOT some new technology that just came out, it’s just a name change. However, with that being said, WP/Husqvarna did change quite a bit to the 2020 suspension settings as they now have their own proprietary setting for the FC450 model (which means they do not share a setting with KTM anymore). Husqvarna went to a softer air pressure setting in the fork to match the valving (going from 10.9 to 10.7 bars in 2020) and also went from a 4.5 rear spring to a 4.2 rear spring. Husqvarna is trying to achieve more comfort for the average rider with these settings in 2020.
Gearing: Husqvarna went from a 13/48 to a 13/49 to help third gear recovery. Having a 13/49 helps the transition when shifting from 2nd-3rd gear and lets the rider feel increased rpm response. I approve of this gearing!
New Mapping: I love that the Husqvarna’s come with a on-the-fly handlebar map switch that offers two maps to choose from (without having to stop). For 2020 map one is what they call the ‘standard’ map, which is designed to have a controllable longer/linear power that is geared towards the non aggressive type of rider. Map two, on the other hand, is what Husqvarna is calling the ‘aggressive’ map that is supposed to be stronger across the board and although it is, it still is very linear feeling. Map two will not explode you out of a corner, but instead give you some added bottom/mid rpm response as well as have a more free feeling engine character. To me the lack of engine braking on map two makes the softer feeling fork dive less on de-cel. TC is still available and works just as good as 2019 so don’t be scared to try it. If you ride hard pack tracks or slippery terrain do yourself a favor put your 2019-2020 Husqvarna FC450 on map two with the “TC” light on and thank me later.
Piston Design: There is an updated piston skirt design for 2020 that is said to help improve durability. Don’t worry I will be the judge of the said durability improvement so make sure you stay tuned to future Rocky Mountain ATV Keefer Tested Podcasts.
Dunlop MX3S Tires: Everyone enjoy these tires on the 2020 Husqvarna’s and KTM’s because we will not see them come 2021 on production machines! Dunlop is forcing manufacturers to go to the MX33 come the year 2021.
Engine Feel (On Track): The engine on the 2020 Husqvarna FC450 does feel slightly different than the 2019. The overall engine character still has that smooth easy to ride feel, but with slightly less engine braking. Coming into corners you can feel less drag on the engine and less movement in the chassis. When in map two there is also more mid-range rpm response on the 2020 thanks to the mapping changes Husqvarna made. No more lean top end de-cel pop and rich bottom end feel that hampered the 2019 version. If you’re looking for a hard hitting 450 engine character this isn’t your type of machine. However, if you’re looking for an easy to ride, connected to the rear wheel feel, deceivingly fast type of power, the Husqvarna could be just what you’re looking for.
Suspension Feel (On Track): Husqvarna/WP will tell you that they set up their 2020 suspension settings for the average consumer that wants comfort out of their motocross machine. They succeeded in getting less mid stroke harshness (de-cel) out of the AER fork, but to me the setting was too soft. I also understand that I am not the target consumer Husqvarna is trying to market this bike to so I took this into consideration. The action of the fork is smoother feeling than last year’s fork setting, moves more in the stroke, but gives the rider a considerable amount of front end traction (for an air fork) on braking bumps. This fork will feel low if you’re a heavier or aggressive type of rider, so going up to 10.8-10.9 bars would be in your best interest. Slowing the rebound down a couple clicks on the fork will also slow the action down a little and keep it from diving too much on jump faces and g-outs. Also don’t forget to bleed your AER fork before every ride. Yes, it has bleed holes.
The WP rear shock still likes a sag of 105mm, but the overall feel of the shock is slightly empty feeling (soft) at the end of the stroke. If slamming into steeper jump faces or g-outs you will bottom out and see rubber marks under the rear fender fairly quickly. If you’re experiencing a lot of this, stiffening your high speed compression a quarter turn and turning in your low speed compression a couple clicks will help the shock’s end stroke feel. What the 2020 rear shock does do better than the 2019 is offer more rear wheel traction on acceleration bumps. The rear wheel drives through square edge chop better and doesn’t give the rider a harsh/spike feel like the 2019 shock did.
Subframe/Motor Mount Bolts: Keep an eye on your two rear subframe bolts and engine mount bolts. On our test bike they worked their way out a little so make sure to keep some blue loctite on them and check them every so often.
Handlebar: The Pro Taper EVO bar is straight and flat, but long at 811mm. Do yourself favor and cut the bar down to 803mm and watch your cornering improve.
What Do I Really Think: The 2020 Husqvarna FC450 is one of the easiest bikes to ride and can be enjoyed by a wide range of riders. I like this attribute! It’s user friendly 450cc nature is not too aggressive for the less experienced type of rider, yet still can get a very experienced rider around the track in a hurry, without a lot of effort. The WP suspension is softer than last year, but also gives the rider slightly more comfort on small bump absorption. The overall feeling of the bike is light around the track and allows the rider to open up his line choices. I will be testing the 2020 Husqvarna FC450 more in the coming weeks and will be getting you some optional settings to try so make sure you stay tuned to pulpmx.com and keeferinctesting.com in the coming weeks.
