Fell in love with this old orange Takara a couple years ago and finally made her mine this past weekend. Quick bath and everything checks out except the rear hub is toast. NBD, heading to the community bike yard today for a replacement wheel. No model name anywhere on the bike except "Sport Series SIS," but I believe this refers to the Shimano SIS shifting system. Model number P8057318 stamped on down tube just before BB, and it doesn't match any serial numbers I've found in my search. Shimano SIS shifting system, JoyTech hubs with Femco rims, 1018 high-tensile steel frame, she's going to be my kid-hauling, grocery-grabbing, beer-pushing orange crush because I can't seem to ride my fixed without becoming a speeding *******.

Any help identifying this beast will be much appreciated.

No idea what the model is, but I'd call it 'beastie". It's a very entry-level machine, and has non-replaceable chainrings (the small one looks like it could stand to be replaced, but that will require changing out the entire drive-side crankarm if I'm seeing it right).

I think your intended purpose for it is very appropriate. Between the fittings it has, and judicious use of p-clamps, this should do fine once it's been overhauled.

Well, the serial number format matches that of Pacific, a Taiwanese manufacturer. It was made in a year that ends in 8 but it\s not 1978 as the logo style doesn't match known samples from that period. Some of those components look like they could be form the late 1990s but they could be replacements and I don't believe the brand lasted that long. I think 1988 is the best candidate. Sorry, I don't know the model.
