Jett Lawrence's AMSOIL Honda CRF250R Race Bike Breakdown

July 31, 2019 / by Donn Maeda

We stopped by the GEICO and AMSOIL Honda race shop to get the full rundown on Jett Lawrence's Honda CRF250R.

The AMA Amateur National Motocross Championships at Loretta Lynn’s Dude Ranch are upon us, and one of the racers expected to contend for the premiere championships at the ranch is 16-year-old Australian Jett Lawrence. Younger brother of GEICO Honda team rider Hunter Lawrence, Jett is often referred to as the more aggressive and hard-charging of the brothers.

The AMSOIL Honda team is one of the largest factory supported efforts in amateur racing, with Jett, Joe Shimoda, Carson Mumford, and Hunter Yoder all pitting beneath the team’s semi awning. That said, building the most effective race bike at a reasonable expense is the team’s number-one priority when it comes to racing. Just before the team rig began the long trek from Corona, California, to Hurricane Mills, Tennessee, we stopped by the immaculate GEICO Honda and AMSOIL Honda race shop to take a closer look at the bike Lawrence will race at the ranch. AMSOIL Honda team mechanic Christien Ducharme built the number-49 CRF250R and was glad to give us a breakdown on what the younger Lawrence brother will line up on this week.

The 2019 Honda CRF250R is highly regarded as one of the best 250s in the class in stock condition, so it doesn’t take a whole lot to make it competitive at the highest level of amateur racing in America. Save for GEICO, which is the pro team’s sponsor, all the same brands back the AMSOIL Honda amateur team. Ducharme’s bike is meticulously prepared and has the look of a true factory machine.

“The idea is to build a bike that is competitive, but not to break the team’s budget,” said Ducharme. “Sure, we could send the amateur kids to Loretta’s on the same bikes that Chase Sexton and the rest line up for at a National MX, but it wouldn’t be feasible because of the expense, and that kind of power isn’t really needed. For an amateur package it is a good, solid platform.”

“With such a big team, we try to save money where we can, so we pick and choose what essential parts we put into the engines to get the power increases,” said Ducharme. Christian Kinny builds engines not only for GEICO Honda, but for AMSOIL Honda as well. Working with Wiseco on piston development, he has come up with a good, competitive package. “In comparison to the pro team bikes there are some things this doesn’t get, like the high-end cams, but the performance really isn’t that far off. Because the engines on the amateur team aren’t built as extensively as the pro team engines, we can get about five more hours out of each of them before we tear them apart. We rebuild the practice bike engines every 20 hours. You could go more, but that’s a good, safe margin. We tear them apart and inspect everything to check for abnormal wear and tear. When it comes to the race engines, of course they are built fresh before each of the major amateur National races.”

All of the AMSOIL Honda team bikes ride on production Showa suspension components that have been modified by Factory Connection. Each rider tests extensively to find the ideal fork and shock settings that work for them. “Thanks to Factory Connection, we have the resources to get the maximum performance out of the production fork and shock,” said Ducharme. “Plus, it gives the guys something to look forward to when they turn pro…the kit stuff.”

The stock Honda front brake caliper is used on Lawrence’s bike, but it is paired with an oversized brake rotor from Motostuff. A Cycra Racing front disc guard is used to protect the system from damage from a rock, rut, or contact with another machine.

The control panel of Lawrence’s machine include Pro Taper oversized handlebars, Pro Taper ¼ Waffle Grips, ARC Levers, and stock triple clamps. “Aftermarket triple clamps are a large expense for a race team, and the stock clamps are strong and have good feel,” said Ducharme. “I buffed out the lower clamp and got rid of the stock casting marks.”

Cycra Racing plastics are used on the entire machine. The Powerflow Radiator Shrouds are designed to flow more air towards the radiators than the stock parts, and they also feature a curved-in uppermost corner so that the riders’ boots do not get caught in corners. Note the plastic mesh added to the radiator louvers to provide additional protection against sand and rocks.

D.I.D wheels are laced up to stock Honda hubs on both ends of the bike. “To be honest, stock hubs are really strong and durable,” said Ducharme. “In the past, we’ve had some trouble with some aftermarket hubs….we’ve had issues with them warping, and with the spokes pulling through. I take the stock hubs and polish them up and make them look better. Jett is actually pretty hard on wheels because he likes to send jumps to the flats, so it is important to have strong, durable wheels on his bike.”

One of the coolest trick parts on Lawrence’s race bike is this carbon fiber tank cover, which guards the titanium fuel cell. The GEICO Honda team use larger-capacity works titanium tanks that don’t use a cover…perhaps this trick cover was available.

The Yoshimura exhaust system is fine-tuned to match the performance of the team’s engine spec. “The exhaust isn’t the same one that the GEICO team uses, its built around the amateur team engine package,” said Ducharme. “Working with the guys at Yoshimura is easy because they’re in Chino, not too far away from our shop.”

Ducharme removes the inner channel of the sidepanel airbox vent. “Every little bit helps when it comes to making power,” he said. “Trimming the channeling out allows for more air to directly reach the airbox and the little things add up. If it’s a wet race with standing water puddled up, I’ll switch back to a non-cut sidepanel.”

“Factory Connection sells aftermarket billet aluminum linkage pull rods which are stronger than stock and come in different lengths for different rear suspension characteristics,” said Ducharme. “Jett actually prefers the way the stock linkage feels, so we had one made up for his bike. It looks trick and it is stronger than the stock cast part.”

“Jett likes to feel connected to the bike, so these wider titanium footpegs obviously offer more traction than the stock pegs,” said Ducharme. “The guys have the option of higher or lower peg heights, but he prefers the standard feel.”

“Jett is a really fun guy to work for,” said Ducharme. “Jett goofs around a lot when he’s not racing, but he knows what he has to do on the track and takes his racing very seriously, which is cool to see out of such a young kid. Aside from his wheels, he is really easy on the bike and he doesn’t beat stuff up. Sometimes, I will put a new clutch in the bike just because I feel bad, but he never seems to need it.”
