2. 2019 Haojue HJ300-A
The engine section of the new 2019 Haojue HJ300-A is the same as the twin-cylinder GSX-250R. This means that an up-sized unit is used and it is built on the same platform as the existing set of multiple genre bikes. Most of the competitors offer both 250cc and 300cc twin engines, indicating that Suzuki and Haojue could do the same. Usually, one powerplant is more popular than the other.
