The 2020 Honda CRF250R is the model that gets the most attention with updates to the engine and transmission.
2020 Honda CRF450R
Alongside optimised PGM-FI engine maps and HRC Launch Control, for 20YM the CRF450R gains a new Honda Selectable Torque Control (HSTC) system, with 3 riding Modes to assist every rider, from beginner to pro, to manage rear wheel traction and gain drive.
The CRF450Rās frame and swingarm are unchanged but there are new compression damping settings for the Showa suspension. The rear brake gets a pad material revised for durability, and the battery box is re-sited.
New graphics for the radiator shrouds complete the update.

2020 Honda CRF250R
The new CRF250R links up its strong bottom-end torque and potent top-end power with a much bigger hit of both through the mid-range; the 19YM CRF450R frame and swingarm now provide the basis for the chassis, with revised damping for the Showa suspension.
Riders love the CRF250Rās top-end power hit. After 19YMās bottom-end improvement, focus of development for the 20YM machine was torque and power in the low-to-mid range. And Hondaās engineers have achieved just that ā plus extra top end power ā with extensive work to the combustion chamber.
The 2nd gear ratio is now closer to 3rd to reduce the natural drop in engine rpm when making that crucial upshift; clutch performance has also been improved. Detailed improvements to intake and exhaust efficiency, plus engine mapping all work together to achieve the overall goal of improved drive.
To match the engine upgrade the new CRF250Rās frame and swingarm are identical to the 19YM CRF450R. Both items are grams lighter but ā more significantly ā have a carefully tuned rigidity balance; combined with new compression damping settings for both front and rear Showa suspension, the result is improved stability, feel and accuracy while tracking through fast, bumpy turns.

2020 Honda CRF450RX
Hondaās cross-country specification CRF450RX is now equipped with Honda Selectable Torque Control, hand-in-hand with optimisation of the PGM-FI and HRC Launch Control mapping. The Showa suspension features revised settings, and there are also updates to the rear brake and graphics.
Alongside optimised PGM-FI engine maps and HRC Launch Control, for 20YM the CRF450RX gains a new Honda Selectable Torque Control (HSTC) system, with 3 riding Modes to assist every rider, from beginner to pro, to manage rear wheel traction and gain drive.
