Here are some pictures.
You can tell its a WR450 engine by the starter hump on the left side cover. Whether or not the starter itself has been retained.
You can also tell because its got the WR air box, not the YZ and the number plates have the WR air vents in them.
Although his engine is carbureted, not fuel injected. But these pictures might have been taken before the FI model came out.
Note the radical skid plate or the lack thereof.
The swing arm has been changed to the newer YZ version.
