Oil Temperature Gauges

Most motorcyclists monitor their speed. Some also keep an eye on the RPMs. However, experienced riders know there's another number just as crucial: the oil temperature.

Engine oil isn't just a lubricant. It cools, protects, cleans, and keeps your power plant alive. For an air-cooled Harley-Davidson or other V-Twin engine, it's especially important to know what's happening inside when you're crawling through city traffic in the summer heat, or devouring miles on the highway for hours on end.

An oil temperature gauge is a simple yet extremely useful tool. With a single glance, it shows you how hard your engine is working, when it has reached operating temperature, and when it's time to ease off the throttle.

Classic gauges, integrated into the oil tank cap, also perfectly fit the world of Harley-Davidson and custom bikes. They are not flashy, not electronic gadgets; they simply do their job – just like the motorcycle accessories of yesteryear.

In this category, you'll find oil temperature gauges that help you better understand your engine's operation and can contribute to maintaining the reliability of your power plant in the long run.

Because the engine always speaks to us. The oil temperature gauge just helps us better understand what it's saying.
