For 2014, Rockstar Energy Racing switched from Suzuki to KTM. Since Davi Millsaps will be out for part of the season due to a knee injury, Ivan Tedesco was signed to carry the team until Millsaps’ return. At Anaheim 1, we took a look at Ivan’s Rockstar Energy Racing KTM 450 SX-F.

According to mechanic Steve Westfall, all of the parts that Rockstar Energy Racing uses on Tedesco’s bike, other than aftermarket goodies, are from KTM. The team also uses Factory Services for all the motor work and service, with the addition of a Hinson clutch.

The most interesting item on the bike at A1 was the WP air shock, which is basically the same that Ryan Dungey ran last year, although it’s second generation. For 2014, Rockstar Energy Racing switched to WP suspension front and rear, and WP does all the service and repair. The forks are 52mm WP, which are not available to the public, although you can by 49mm forks from KTM Hard Parts.

Another switch the team made for this year was the move to FMF exhaust systems.

“The FMF Exhaust works great with the motor setup,” says Westfall. “It really works well with our motor setup.”

Westfall admits that his favorite features are the hydraulic clutch and the electric start. “Everyone loves the feel of the clutch; it never fades and you never have to adjust it,” says Westfall.

Other items include Brembo brakes front and rear, which are anodized; Talon carbon fiber hubs and A60 wheels; and Neken triple clamps, which are standard 22mm offset.

According to Westfall, they detuned the bike a little for Tedesco from what Millsaps’ settings.

“Ivan has a tendency to be real aggressive on the throttle, instead of being smooth with it, so we had to mellow it out, which tells you how much power the bike has,” says Westfall.

As for the suspension, Tedesco likes the fork to be very progressive, getting increasingly stiffer through the bottom of the stroke for Supercross.

“The shock is what I would call middle of the road,” says Westfall. “The air shock is not as soft at the top as a conventional shock, but it gets a little bit stiff than a conventional shock as it goes through the stroke.”
