Yamaha RS100 Model and Catalog Context
Yamaha's product history records the RS100 in its 1975 motorcycle lineup, and Yamaha's U.S. parts catalog identifies the 1975 model as RS100B within the RS100 family. PartsNMore's current RS product tags cover RS100 applications for 1975 and 1976. Use the full model suffix and the product-specific year rather than assuming every RS100 component is unchanged across both years.
The exact Yamaha RS tag currently matches one active 14-tooth front sprocket and two archived brake-shoe records. Archived records are not presented as current shopping choices. The live collection copy therefore focuses on the sprocket that customers can presently order.
