The Yosemite went to Shimano 500LX in 1992 and Deore LX in 1993, so everything is pointing towards a 1991 model.
I thought it a short serial too....I can't make any sense of it other than maybe the 041 means the 41st bike in production that yr. And maybe the 'S' and the 'K' are date code month and yr?
'91 makes sense in my remembered timeline. Do you know how much the bike would have listed for retail? I can't imagine my then wife letting my boys go crazy on this as a gift, unless the salesperson was gifted....lol.
Be awesome if Harrington would chime in on this.
