My front axel, front seals/bearings on my Templar appear to be identical to a ~20 year old Honda CRF 250 (by dimensions, haven't purchased or tested). So axels have the same diameter on the 20 year old CRF, I think.
But I don't know about the newer models listed as compatible on the nice looking wheels you posted (CRF250L 2013-2020, etc).
You also have to match the axel spacers on each side to the forks and the swingarm legs, and you have to match the offset for the disk rotors (both wheels) and sprocket mounting. Those are also wider wheels, for wider tires. You need to find tires compatible with those wheels that fit in the swingarm on the Templar...
You need either all of those measurements, or buy them and compare them. Then post the results here, please!
