Riding off-road throws up a wide variety of conditions. To make the CRF450L’s engine more usable–with strong, smooth torque to hunt out every last scrap of rear wheel traction–we gave it 13% more crank inertia plus revised valve timing. Because if you’re spinning a rear wheel you’re not going anywhere.

THE BALANCE OF POWER

And why it matters…

The CRF450L’s electric-start, 449cc four-valve Unicam engine delivers a smooth spread of torque from low rpm up, helping the rear tyre hook up no matter the ground conditions. Developed in conjunction with the CRF450RX enduro machine it uniquely features a heavier crank mass and compression ratio of 12.0:1. The piston uses 3 rings for long-term durability and the ACG has been uprated to provide electrical power for the lights and maintain battery charge during lower-speed running.

Torque versus power

Away from the MX track too much peak power saps precious energy. On the trail torque that finds drive is what matters and the CRF450L makes a strong, fluid 32Nm balanced by power of 18kW, making life easy for its rider, not harder.

Real world service intervals

Honda is legendary for its engineering ability and high build quality. The CRF450L was designed from the outset to have an air/oil filter change every 1,000km, with a major overhaul only required at 32,000km intervals.
