Monster Energy/Yamalube/Star/Yamaha Racing signed Jarrett Frye for the 2019 season to race the Schoolboy 2 and B classes at this year's high-profile amateur races. So far, the Mechanicsville, Maryland, native has served his team well, finishing as the most successful rider at the recent Ricky Carmichael Daytona Amateur Supercross (RCSX), with wins in every race he entered including main events in 250B, 450B, and Schoolboy 2.

Dirt Rider contributor Shan Moore got the opportunity to check out Frye's racebike at the James Stewart Freestone Spring Championship in March, where Frye's mechanic and brother, Georgie, gave us the details on the YZ250F.

According to Georgie, Star Racing begins with a stock bike and sets it up according to Jarrett’s preferences using a variety of aftermarket parts. Frye runs a Rekluse Core Manual TorqDrive clutch and according to Georgie, the full FMF exhaust system is a straight-out-of-the-box, production unit. Several other parts are used inside the modified powerplant.

“When it comes to the engine, we run a lot of GYTR products,” Georgie said. “Crank Works supplies our cranks and we use Vortex ECUs. Our pistons are from Wossner. The water pump is standard. We have an in-line water temperature sensor instead of the one that’s mounted to the side of the head just for vibration and rigidity issues.”

The KYB suspension is set up in-house and Georgie told us Jarrett likes it set up on the stiff side. The team runs Vortex sprockets, EK chains, and standard size Braking rotors front and rear. The hubs, rims, and spokes are all stock items right out of the crate. The radiators are also stock with Twin Air covers to prevent mud from packing in them, which helps keep the bike running cool. The footpegs are Raptor Titanium units with a little modification done by the team.

“We cut the center [of the footpeg] out so it doesn’t hold mud,” Georgie said. “Also, Jarrett likes the Neken 187-bend handlebars, and we run ARC brake and clutch levers. The triple clamps are Neken with the stock offset.”
