Jett Lawrence is one of the most highly touted Supercross rookies in 2020. The 16-year-old Australian began his professional racing career at Unadilla MX for round 10 of the 2019 Lucas Oil AMA Pro Motocross Championship this past summer, where he finished 13th overall in the 250MX class and repeated that same overall finish position two weeks later at the series finale at Ironman Raceway in Crawfordsville, Indiana.

Lawrence’s mechanic Christien Ducharme gave us a rundown of the 16-year-old Aussie’s factory Honda CRF250R the day before he began his 2020 Monster Energy AMA Supercross campaign.

For 2020, Lawrence is competing in his rookie season of Monster Energy AMA Supercross, contesting the highly competitive Western Regional 250SX Class Championship. At the opening round at Anaheim 1, he finished ninth in the main event despite succumbing to food poisoning the night before. The young racer improved the following weekend at round 2 in St. Louis by capturing his first top five finish. At round 3 back at Angel Stadium for Anaheim 2, he led 16 laps of the main event before relinquishing the lead to Dylan Ferrandis on the final lap, and suffered a violent crash in the challenging whoop section that left him with a broken collarbone. The day before Lawrence began his 2020 Supercross campaign, his mechanic Christien Ducharme gave us a rundown of his factory Honda CRF250R.

“Jett’s bike is pretty trick,” Ducharme began. “[There are] a lot of really cool things to the untrained eye. A lot of our electronics is done in-house, so obviously that varies from stock [with] the cool connectors and all that.”

The Yoshimura RS-9T exhaust system features a titanium header pipe and titanium mufflers with carbon fiber end caps. The left-side header pipe has a special bung welded on it to accommodate an O2 sensor for data acquisition purposes.

A Hinson Racing clutch is used in the engine and coolant flows through CV4 radiator hoses. Maxima Racing Oils is a new sponsor for the team in 2020, and it provides the team with ProFilter air filters and chemicals. Geico Honda relies on Vortex ignitions, and changes the mapping according to rider preference and weather conditions.

“We do all of our [mapping] stuff through Vortex,” Ducharme said. “[The mapping] depends on the day [and] the weather [as far as] how rich [or] how lean you want to go. If it’s cold, obviously you can get away with a little richer [of a] setup, but if it’s really hot, you want to lean it out fuel-wise.”

Gracing the front and rear of Lawrence’s bike are Showa A-Kit suspension components, which are set up by Factory Connection. Lawrence prefers the fork and shock to have a progressive action.

Showa A-Kit suspension components grace the front and rear of Lawrence’s bike; they’re set up by Factory Connection. The young Australian prefers the fork and shock to have a progressive action.

“He likes his suspension [to have] a little bit more feel on the initial part [of the stroke],” Ducharme explained. “But he also likes it to hold up when he’s really charging [such as when] landing from a big rhythm into a turn. He likes to have the confidence that his bike is going to hold up [on a big impact].”

Honda Performance Development (HPD) provides the team with a number of works Honda parts including the triple clamps and bar mounts.

The triple clamps, bar mounts, hubs, footpegs, and footpeg mounts are all works Honda parts from Honda Performance Development (HPD). The engine hangers have a hole drilled in them for additional flex and a titanium bolt kit is used to help save weight. In addition to taking care of the team’s suspension, Factory Connection also provides the pullrods, which stand out with a bright red anodized finish.

The front brake master cylinder features a custom carbon fiber guard that protects the lower portion of it. Ducharme pointed out that Lawrence prefers his levers to be positioned far in on the handlebar.

A CMI shifter replaces the stock unit and Moto Stuff provides the brake rotors—the front being protected by a carbon fiber disc cover. D.I.D supplies the chain and DirtStar LT-X rims, while the handlebar, grips, and sprockets are all from ProTaper. The front brake master cylinder features a custom carbon fiber guard that protects the lower portion of it. The clutch perch, clutch lever, and front brake lever are ARC units, and Lawrence prefers the position of his levers to be far in on the handlebar.

“He doesn’t really run anything too far out of the [ordinary],” Ducharme noted. “He’s kind of on a neutral bar bend—something not too high [and] not too low. Same thing [with] his bar mounts—kind of in the middle. The lever position is kind of out of the ordinary; the levers are [positioned] really far in [on the handlebar]. Everything else is pretty standard.”

The skid plate is stock, but the team adds coverage to each side at the front of it to further protect the ignition cover, oil filter cover, and water pump cover. The Cycra Stadium front number plate covers the lower triple clamps to shield them from roost, and the Thomasville, North Carolina-based manufacturer provides the plastics for the rest of the bike as well. The seat cover and graphics come from D’Cor Visuals. Dunlop race spec tires grace the front and rear of Lawrence’s bike, and Ducharme told us the entire team runs the same tires.
