Gone are the days of mail-order catalogs and begging the local mechanic to change his stock.
There are now a number of sites that are basically RockAuto for motorcycles where you can order OEM and aftermarket motorcycle parts and have them shipped right to your door.
RevZilla
Most people know Revzilla is one of the best places to go for motorcycle gear. It’s not just helmets and jackets, though. Revzilla has a good selection of spare parts, particularly standard maintenance items like oil filters and batteries.
You can get some aftermarket parts for modifications, as well, but the selection is admittedly better for Harleys and more recent models. A new exhaust for your 2005 Ninja? Keep reading.
Amazon
You should always check Amazon regardless of what you’re looking for. The prices are great, and the shipping is unbeatable.
The only issue is that the availability of parts is pretty hit or miss. With so many different sellers, there’s no rhyme or reason to what parts you can find.
I suggest just quickly checking for what you need and if it doesn’t come up, move on.
Partzilla
Despite similar names and even similar website designs, Partzilla and RevZilla are not at all related. RevZilla is owned by Comoto, while Partzilla is part of the Outdoor Network, a group of distributors for OEM and aftermarket parts.
Partzilla is the place to go if you need replacement parts or are modifying your bike and looking for an unusual or hard-to-find part. The catch? It only focuses on a few motorcycle brands, namely Honda, Yamaha, Kawasaki, and Suzuki.
You can potentially find an OEM part compatible with your Fat Boy if you know where to look, but it will not be as easy as replacing the starter on your Ninja.
eBay
You might think of eBay as a place to bid on antiques and old baseball cards, but it’s actually one of the best places to find OEM aftermarket motorcycle parts, even new ones.
You can sort by your specific make, model, and year, and you can also find great deals on full kits and other hobbyist items. And, of course, if you don’t mind getting a scrapped part, it’s the way to go.
RonAyers.com
The best thing about RonAyers.com is that it’s totally devoted to OEM and aftermarket parts. This means that on top of a wide, detailed selection, it also has helpful customer service and useful guides.
Like Partzilla, RonAyers.com focuses more on Japanese bikes that are easy to customize: Honda, Suzuki, Kawasaki, and Yamaha. It’s not so much the place to find parts for chopping your Harley or rebuilding an old Indian.
