Today I just reached 7,500 miles on the odometer of my new Zongshen Sierra 200 motorcycle. I could not be more pleased with this machine. I average 75 mpg, and the bike will cruise at 60 mph all day long. I have not had any mechanical problems whatsoever. The Zongshen engine and the TK MV28 carburetor on this motorcycle are superb. No one should bash this motorcycle. It is an excellent bike for the price, and I would buy another one just like it in a heartbeat.
