Reigning and two-time SuperEnduro World Champion Colton Haaker has had a steady start to this year’s championship. Since cutting his AMA Endurcross season short with an elbow injury he hasn’t quite looked himself.

But that’s enough about the man, he can talk for himself. What we want to know is what's different about the Husqvarna FX 350 he races in SuperEnduro this year?

Colton’s right-hand man, mechanic Josh Schaecher, runs us through Colton’s 2018 SuperEnduro set-up.

“The FX is Husqvarna’s Cross Country model and shares the engine and chassis with the FC, motocross models. The transmission is pretty standard but is a five-speed gearbox straight out the FC model. In fact Colton rides the whole course in second gear as a rule. The 350 four stroke gives enough range to stick with one gear.

“He starts in second gear and runs the whole course. You could damn near take that shifter off and it wouldn’t matter. With the 12-51 final gear ratio the bike delivers a hard hit off the bottom so the engine tune, and mapping is pretty much standard also.

“It’s a stock engine otherwise but hand-built by the Husky Factory who just take it apart and rebuild it with strengthened engine cases. It has the 9mm clutch master cylinder and the Rekluse Manual clutch running the stock fibres and plates with the Rekluse basket.

"We run stock radiators without a fan but use a 2.0 radiator cap to prevent the over-flow if it gets hot indoors. The motocross catch tank is cool though, from IMS. It sits in the frame down tube. The only time I’ve seen it over-heat was in Poland where the dirt was so soft and he was doing starts. The IMS design means it sucks coolant back in when the engine cools.

“Maintenance is minimum in SuperEnduro. It’s one of the things about this sport – the bike doesn’t get worked that hard in five rounds. It runs around an hour during each event so five hours in total. I’m simply changing oil, oil filter, checking the oil screen after every race.

“The Pro Taper bars are the FCR bend with Pro Taper Super Soft grips. ARC front brake lever is the ‘fold forward’ type so any spills on track doesn’t break it. We also run the grippier Guts Racing seat cover. Braking rotor is protected at the front with a Cycra carbon guard and the rear is a Zip-Ty aluminium shark fin.

“The IMS footpegs are a little bit smaller than standard. We asked IMS to make a footpeg the same size as the previous model but 5mm down and 5mm back, to help the standing riding position keep the front end light.

“The Enduro Engineering brake pedal is pretty cool. You could bend the crap out of that thing and he’s still going to be able to use it.

“There are no special exhaust part fitted just the standard FMF ‘drop down’ header which gives plenty of torque and the 4.1 end can but these are off the shelf parts from FMF.


“We use 90/90-21 Dunlop MX52 front tyre and the 756 rear tyre “with the gummy compound” which his being phased-out. To most people in the States we just call it the Gummy because it was the first of its kind soft tyre for extreme.

“We run ‘Tire Balls’ inside, though I’m not saying how many! Tire Balls give more consistent feel and you can change them according to the track. With a mousse the only thing you can do is drill holes and the only thing a mousse is gonna do after that is get softer. Tire Balls are like being able to change the tyre pressure for the track.

“Colton runs WP’s 48 Cone Valve forks that allow the fine tuning of set-up so we can dial in a soft first half of the stroke but firm in the second half. We want to have a plush soft feeling through all the small bumps but when he’s hitting stuff fast we don’t want it to blow all the way through.

“With the WP Traxx rear shock we run a lower sag for SuperEnduro because we want the front end to be light. But it’s maybe more firm in the second half of the stroke because he hits stuff so hard sometimes that we have to worry about the rear end kicking back.

"As far as settings go we keep the bike pretty consistent because we like to adjust the riding not the bike to different tracks. It’s more important to know what the bike is going to do and stick with it.” Says Schaecher.


All-in Colton Haaker’s SuperEnduro bike is more standard than we expected to find. Dig a little and you find some unique parts but essentially this is a bike you could get out your wallet and pay for. And that says plenty about the double world SuperEnduro’s riding talent.
