AN is a motorcycle model of Suzuki of Japan. The most common ones in China are Haojue’s Neptune and Jinan Suzuki’s Superman. However, for motorcycles produced in China, you need to use the manufacturer’s name when applying for a CD catalog. The name abbreviation is used as a model mark. HS is the abbreviation of HAOJUE (Haojue) and SUZUKI (Suzuki trademark). The QS in QS150T (Qingqi Suzuki Superman) is the abbreviation of the initial letters of Qingqi and Suzuki. The same is true for other brands. In other words, JYM125-2 is the same as Tianjian YBR125.

These two models are originally the same product, but they have two different names, so there is no difference.
