However, I notice that you are located in the Philippines. Model specs and names often vary between markets, which complicates identification.

From a component perspective, the closest USA models are the Colorado, which used 500LX components that were 2 groups higher than 300LX, and the Backroads, which used the 200GS components that were one group below 300LX. The frame style itself resembles the Manitoba model, which was one step below the Backroads.

The only USA market Nishiki with a suspension fork in 1992 was the top of the line Alien SP. It was rare to have suspension forks at this level in 1992, so I strongly suspect that they were added by the previous owner.

Regrettably, the only thing that I can tell you for sure, is that it is a 1992 model. Based on the frame and components, I'd classify it as upper entry level. With the OEM rigid fork, it would have had a retail price of around $375-$400 USA, had it been available in the USA market. Selective photo assist...
