What Weight is Harley Type E Fork Oil

Harley-Davidson Type E Fork Oil is a 10Wt oil. This means that it has an average viscosity of 10W, or 10,000 cP. The recommended fork oil capacity for a Harley Davidson motorcycle is 4 oz.

Harley type E fork oil is a very light weight oil that is specifically designed for use in Harley Davidson motorcycles. This oil is much lighter than most other oils on the market, and it provides a smoother ride for your motorcycle. If you are looking for an oil that will give you a smoother ride and better performance, then Harley type E fork oil is the way to go.

Harley Type B Fork Oil Weight

Harley-Davidson recommends a specific fork oil weight for each of its motorcycles. This is because the correct oil weight ensures optimal performance and protects your forks from wear and tear. The Type B fork oil is recommended for all Harley-Davidson models except those with air-suspended forks, such as the CVO Limited, CVO Road Glide Ultra, and Street Glide Special.

For these models, use Harley-Davidson Type E Fork Oil. To find the recommended fork oil weight for your motorcycle, consult your owner’s manual or see an authorized Harley dealer.

What Weight Oil for Harley Forks?

Harley-Davidson recommends using SAE 30 oil in the forks of its motorcycles. This is a light weight oil that helps to keep the forks lubricated and operating smoothly.

What Weight is Type E?

There is no definitive answer to this question as the weight of Type E varies depending on a number of factors, including the specific subtype of Type E. However, in general, Type E is considered to be a relatively lightweight type, with many subtypes falling within the 50-75kg range. This makes Type E ideal for a wide variety of activities and sports, from long-distance running to gymnastics. Additionally, due to their light build, people of this type are often able to move more quickly and easily than those of other body types.

What Viscosity Fork Oil Should I Use?

There is no definitive answer to this question as it depends on a number of factors, including the type of motorcycle, the conditions you ride in and your personal preferences. However, we can give you some general guidelines to help you choose the right viscosity fork oil for your bike. The first thing to consider is the type of motorcycle you have.

If you have a lightweight bike, such as a sportsbike, then you will need a lighter weight fork oil. This will help to improve suspension performance and give you better handling. On the other hand, if you have a heavier bike, such as a cruiser or touring motorcycle, then you will need a thicker fork oil.

This will provide better damping and resistance to stiction. Next, consider the conditions that you typically ride in. If you ride in hot weather or on dusty trails, then you will need an oil with higher viscosity.

This will help to prevent foaming and protect your forks from wear and tear. Conversely, if you ride in cold weather or on smooth roads, then you can use a lower viscosity oil without sacrificing performance. Finally, it is important to choose an oil that meets your personal preferences.

Some riders prefer a smoother ride while others like more responsive handling. Ultimately, it is up to you to experiment with different oils until you find one that delivers the perfect balance of performance and comfort for your needs.

Does Fork Oil Weight Matter?

Fork oil weight is something that often gets overlooked when people are servicing their forks. A lot of people will just use the same weight oil that was in there previously without giving it much thought. However, fork oil weight does matter and can affect the performance of your forks.

The main reason why fork oil weight matters is because it affects the damping of your forks. Damping is what controls the amount of force that is exerted on the fork spring when you hit a bump. If you have too much or too little damping, it can make your ride either overly harsh or bouncy and mushy.

The perfect balance of damping will give you a plush ride that soaks up small bumps but doesn’t feel like it’s bottoming out on bigger hits. Fork oil weights are typically expressed in centistokes (cSt). The lower the cSt number, the thinner the oil and vice versa.

For example, 10wt fork oil would be thinner than 20wt fork oil. Most stock bikes come with somewhere between 10-15wtfork oil depending on the model and year. If you find that your bike feels too harsh or bouncy, you may want to experiment with a different weight to see if it makes a difference.

Just remember that if you go too thin, you risk damaging your seals; too thick and your forks could start to feel sluggish. Generally speaking, lighter weight oils will offer better small bump compliance but can bottom out more easily on big hits. Heavier oils will resist bottoming out better but can sacrifice some small bump compliance as a result.


The Harley Type E fork oil is a great choice for those looking to add a little weight to their forks. This oil is slightly heavier than the stock oil, but it does not add much bulk. The Harley Type E fork oil also has a higher viscosity, which means it will last longer and provide better fork protection.
