2020 Honda CRF250RX Dyno Test

Dyno numbers on Big Red’s 250F cross-country bike.

In its second year on the market, the 2020 Honda CRF250RX cross-country racer features a different exhaust cam profile, a new combustion chamber shape, optimized ignition timing at 8,000 rpm, a revised exhaust system, and a new air filter. Setting itself apart from its motocrosser stablemate, the CRF250R, from which it is based, the RX model features an 18-inch rear wheel, kickstand, O-ring chain, and off-road-optimized suspension settings.

Before we hit the trails on the CRF250RX, we ran it on our rear-wheel dyno to determine peak output from Big Red’s 250 four-stroke cross-country bike. We documented 38.2 hp at 11,900 rpm and 17.9 pound-feet of torque at 9,300 rpm.
