Looking through the Honda UK website a few days ago I saw that Honda have now released a fully road going version of their CRF450, noise and emissions compliant and presumably robust enough for many miles of normal road use.
Now, back in the day when the CB250RS was a current or recent model a few people sucessfully swapped the motor for an XL500 unit without much in the way of specialist engineering. Doesn't that get you wondering how similar the CRF450 crank cases are to our CBR250Rs?
Or could there be a chance that Honda might use that motor in more models?
CBR450R KTM RC390 beater? CRF450 Rally?
