I purchased a farm used 2007 Hisun 700 back in January 2019. early thoughts were not that great of the machine but after using it for 5 months on a pipeline project, I changed my mind. I did do some minor maintaining early on. Oil changes of the diffs and engine and a new battery, spark plug etc. Like I said, ran it for a full 5 months and it never let me down. So after the 5 months of being a work horse, I had the ball joints replaced with Yamaha Rhino ones. Plus the secondary and primary clutches. Added a voltage gauge and usb charger, added an actual temp gauge ( Cheap not working unless moving).
All in all, I haven't used it for work or play in a year since all the clutch work but after sitting all winter, it started right up and ran awesome for year old gas. I paid $2600 for it and used it for work which pays me to use it. Best investment to date. I would buy another hisun if I can get it at a good price an day of the week. If i need parts I head to the Yamaha shop and get parts.
