I found this MOC on rebrickable.com.
I have built it with lot of fun and really like this MOC. It is very detailed and close to the original Sherp ATV. Using a differential gear for steering in combination with S-Brick is a great design. Many thankx to the designer of this MOC: Kevin Moo.
After building the Sherp ATV I made these modifications by myself: - Using technic chains instead of a sequence of 9 gears on each side. This is exactly like the transmission of the real Sherp ATV and it more stable and has less backlash - Modified front door for easy step in of a driver - Filling some gaps on the ground plate - Fixing middle part of PF lights cables
