Dot 3 brake fluid can be used in Harley motorcycles, however it is not the recommended fluid. Dot 4 brake fluid is a higher performance fluid and is what Harley recommends for their bikes. Dot 3 brake fluid has a lower boiling point than Dot 4, which means it is more likely to cause brake fade.

Brake Fluid Price
Brake fluid is one of the most important fluids in your vehicle, and it’s also one of the most expensive. The average price of brake fluid is around $30 per gallon, but it can range anywhere from $15 to $50 per gallon. There are a few factors that will affect the price of brake fluid, including the type of vehicle you have and the brand of fluid you choose.
The type of vehicle you have will be the biggest factor in determining the price of your brake fluid. If you have a luxury car or SUV, you can expect to pay more for your brake fluid than someone with a standard sedan or truck. This is because luxury vehicles require a higher quality and more expensive brake fluid to ensure proper performance.
The brand of brake fluid you choose will also affect the price. There are many different brands on the market, and each one offers its own unique benefits. Some brands are cheaper than others, but they may not offer the same level of quality or performance.
When choosing a brand, be sure to do your research to find one that meets your needs and budget.

What Brake Fluid is Recommended for Harley Davidson?
Harley-Davidson recommends using DOT 3 or 4 brake fluid in their motorcycles. DOT 3 is a glycol-based fluid that can absorb water, while DOT 4 is a silicone-based fluid that doesn’t absorb water but has a lower boiling point. Either type of fluid will work fine in Harley motorcycles, so it’s up to the rider to decide which one they prefer.
What Happens If You Use Dot 3 Instead of Dot 4 Brake Fluid?
If you use DOT 3 brake fluid instead of DOT 4, your brakes will not work as well. DOT 3 is a lower-performance brake fluid and does not provide the same level of braking power as DOT 4.
Do You Have to Use Harley Brake Fluid?
Harley-Davidson recommends that you use their brand of brake fluid in your motorcycle. This is because Harley-Davidson has tested their fluids to make sure they are compatible with the materials used in their braking system components. Other fluids may not be compatible and could cause damage.
Can You Use Dot 3 Brake Fluid in a Motorcycle Clutch?
DOT 3 brake fluid is a glycol-based fluid that can be used in motorcycle clutches, but it is not the recommended fluid. DOT 4 and DOT 5.1 fluids are designed specifically for use in motorcycle clutches and provide better performance.
