Author : Levi Fysh | Published On : 25 Feb 2026

Harley Davidson, a motorbike known for its majestic structure and performance holds so much of class and beauty in it, that you will almost forget to look at some other bike crossing the road at the same time. There is one thing that sets apart a Harley Davidson from other motorbikes and its none other than the charisma the two-wheeler showcases.

People owning a Harley Davidson in Brisbane know exactly how precious their motorbike is; and that is completely the reason why they will not choose to compromise on its parts and accessories when it comes to a replacement or upgrade of the bike.

An important aspect that owners of a Harley Davidson find confusing is, whether they should replace a part or get it done by a professional. So, here is the answer. If you are confident to handle a Harley Davidson, you are good enough to do it by yourself. However, if ever your mind makes you think that you need professional help, just go and get it done by an expert.

However, the next most confusing thing about a replacement or upgrade is, which part to choose, an OEM or an aftermarket?

The twist is, most often owners get overwhelmed when asked to choose between these. If your bike needs a repair and you are taking it to a dealership service store, they are most likely to offer you an OEM part rather than an after-market one.

Understanding the OEM Part and An After-Market Part

Basically, being a Harley Davidson owner in Brisbane makes you choosy about the things you buy for your motorbike. So, when it comes to choosing between an OEM and aftermarket part, you should make a thorough research because each option has its own side of merits and demerits for that matter.

OEM Parts

OEM parts are originally, the factory-made ones which are produced by Harley Davidson itself. Remember these are the components that are the same as the ones your HD motorbike came along with. With its high quality and even higher performance, owners mostly prefer to buy them as they also fit seamlessly and ensure maximum reliability. However, an OEM part is always costlier.

After-Market Parts

These are parts and accessories which are manufactured by a third-party company that replicates the original parts. From high performance upgrades made for a Harley Davidson to the budget-friendly substitute, aftermarket parts can range between any of these. They however may have compatibility issues.

Now, you can choose a Harley Davidson part or accessory accordingly.
