Welcome!
I'm not much of a sport bike guy, but those look really good; I like the twin disc front brake setup. Not sure which engine that one is patterned after, but someone on here will know.
It helps to have a sense of humour to own a China bike. The engines are usually really good, but often the bolts, bushings and chains are junk. Most of us upgrade such things, carefully prep our bikes and ride 'em.
