Conquer Dirt
We've taken our revolutionary YZ four stroke motocross technology and applied it to the enduro world. Rearward slanted engine, reversed cylinder, forward mounted fuel injection and a compact chassis are just some of the key features found on the WR250F. Delivering light, agile handling on tight trails, the WR is also a great choice for the experienced recreational rider too. |
Performance
The latest generation YZ250F engine is the inspiration for the WR power plant. A forward mounted 44 mm fuel injection system supplies fuel to the 4-valve cylinder head, while the wrap around exhaust removes the spent charge and centralizes mass at the same time. A couple of items you won't find on a YZ250F is the WR's 6-speed transmission, electric starting and radiator cooling fan. Key improvement for 2018 are revised engine internals and ECU which help round out this top performing off-roader. |
Frame & Suspension
The adjustable KYB suspension found on our WRs are considered by many to be the best in the business. Revised front and rear suspension settings for 2018 provides better rider feedback to improve performance and handling. The chassis design centralizes mass for fast, accurate, and agile handling. |

"Reversed" engine design (FI system is front mounted, exhaust exits from rear of cylinder).
- FI throttle body & air box are front mounted, providing a straight intake path
- straight intake path into the cylinder, provides optimum fuel / air flow for excellent power
- front mounted intake design keeps fuel cooler since engine heat has less effect on incoming fuel (cooler fuel is more dense & increases power)
- design also helps centralize mass for light, agile handling
-
Electric start with auto decompression system.
