Does the bike have a windshield, and if so, how does it contribute to the rider's comfort and reduce fatigue during long rides?

No, the Suzuki Avenis does not come with a fuel injection system. Instead, it uses a carburetor fuel system, which delivers fuel to the engine by mixing air with fuel before combustion. Carburetors are simpler than fuel injection systems and are often found on smaller bikes like the Avenis. However, fuel injection systems can offer better fuel efficiency and smoother power delivery.
