加拿大采购需求：越野车、全地形车、多用途全地形车、110 型全地形车、柴油全地形车、四轮驱动车

I'm looking for detailed info on your ATVs, specifically about the fuel system—are they carburetor or electronic fuel injection? Also, do both models feature independent rear suspension? I've heard some issues with parts availability led to certain dealers dropping your brand. Can you clarify how parts can be ordered? Do I need to go directly through China for parts, and can non-retail consumers make direct purchases? Appreciate your help!
