Don't know about the US version but the '00 had the small YZ tank, the aluminium radiators, and the choke and hot start knobs inserted on the carburator
I have a '99 and it has choke and hot-start on the carb... Canadian model I think (or US... same? North American Model perhaps?) So the Can / US / North American model may have been different than what was available to you in portugal. Anyone else know for sure?
not sure if the rads are aluminum but they certainly appear to be, and the tank is a 3.3 IMS
aftermarket with YZF shrouds now, and it came to me that way so I have no clue which tank came on it originally, however i doubt it would have been the same as the YZF because the shrouds are different on the 99s between the YZF and the WRF, I think... Again... any others able to confirm this?
