2026 Honda CRF450R Build & Race Prep

Follow our 2026 Honda CRF450R from the dealership floor through race prep, setup and the first ride. We'll share the work behind the build, the reasons for each change and what we learn when the bike hits the dirt.

Race prep is underway. See our chassis inspection and bearing-service photos below. ECU reprogramming is next.

Update 01 • The Starting Point

Stock Bike. First Steps.

Our starting point was a brand-new 2026 Honda CRF450R with zero hours and everything stock. Before performance changes or the first ride, we opened up the chassis for inspection and bearing service. The latest update below takes you inside that work.

Update 02 • Race Prep & Chassis Service

New Bike? Check the Bearings. Grease the Chassis.

Brand new doesn't mean ready for the first ride. Our 2026 Honda CRF450R came apart for race prep, and the chassis bearings we inspected were virtually dry. Before the performance upgrades, we're taking care of the basics.

This stage focuses on opening up the chassis, inspecting the bearing areas and greasing the serviceable bearings. The steering head, swingarm and suspension linkage all get attention.

Our shop advice: don't assume a new bike is properly greased.

Check the chassis bearings before the first ride. Inspect them. Grease them. Then go ride.

Race Prep Notes

What we're addressing: Chassis bearing inspection and lubrication before the first ride.
Why it matters on this build: We found virtually dry bearing areas on a brand-new bike.
Areas covered: Steering head, swingarm pivot and suspension linkage, with the rear axle and adjuster area also opened up during prep.
Shop takeaway: Make chassis inspection and greasing part of your new-bike preparation.
Ride feedback: To follow as the build moves into testing.
