Another interesting observation is that the colour is the same as the 1992 Ravine (that came with 400LX) but the frame design is the same as the 1993 bikes with the seatstays without the Raleigh Logo and welded differently (possibly due to frame failures).
Like Paul said I was also thinking an export bike for somewhere where one of the other regular names was not suitable (like the mitsubishi pajero in Spanish speaking communities).
