When used in urban areas with heavy traffic and frequent stops and starts, the mechanical parts of motorcycles are subjected to significant stress. Such types of usages favors deposit build-up, excessive wear on the engine and clutch, and an increased risk of breakdowns and mechanical failure.

In addition, the more recent introduction of biofuels can have an impact on engine operation. Depending on the availability of different types of fuel, some users may switch from one to another, hence the importance of lubricant and fuel compatibility.
