check the right side of the tunnel by the footrest, you should find a model number or a serial number there.
otherwise, if the motor is a monoblock (1 jug that houses all 3 cylinders), it is an xcr 600 in the wedge body (white hood). if the motor has three individual cylinders, it is an xcr 600 SP in the aggressive body (black hood). note the difference in naming between a 1996 XCR 600 and a 1996 XCR 600 SP. polaris dropped the ball for naming 2 completely different sleds almost exactly the same name
1999 Polaris XC 500
