The decision
When you shop the motorcycles scooters aisle, you are not always comparing one type of item to another. These four listings make that obvious: one is a performance chain, one is a replacement spark plug, one is a cleaning brush, and one is a complete used custom motorcycle. The listed price spread runs from $5.00 to $11,750.00, so the real question is not which item is best. The real question is which one matches the job you have right now.
Quick take
If you need a new street-motorcycle chain, the Vortex Racing V3 2.0 Chain is the only chain here. If you need a spark plug for a Harley-Davidson street motorcycle, the CHAMP ion RA8HC is built for that fitment range. If you just need to clean chain oil and dirt off the bike you already own, the universal blue brush is the tool for that job. If you want a complete used bobber instead of a part, the 2005 Custom Built Motorcycles Bulldozer is the only full motorcycle here.

Product notes
Vortex Racing V3 2.0 Chain 520RX3-120 for Street Motorcycles, Gold
The Vortex chain is the right pick when you already know your street motorcycle uses a 520RX3 size and you want a chain that can handle high-performance duty. This is a new part made in the United States, and its x-ring seals plus drilled links are aimed at reducing friction and rotating mass. It comes with a rivet master link, so the installation path includes a chain tool and careful work. The limitation is that this is not a universal accessory: it is built for a specific street-motorcycle chain spec, and it is the second most expensive item here after the full motorcycle, so it belongs in a real chain-drive project, not a casual tool kit.
CHAMP ion Spark Plug RA8HC for Harley-Davidson Street Motorcycles
If you own a Harley-Davidson street motorcycle, the CHAMP plug is the ignition part to look at. The RA8HC uses a copper core electrode and a long insulator nose, which are meant to improve conductivity and resist fouling. The fitment list spans Softail, Dyna, Sportster, Road King, Street Glide, Electra-Glide, and Buell models, so it is a sensible starting point for many Harley-Davidson owners. On the other hand, this is a single spark plug, so it takes care of one cylinder at a time rather than a complete set. It is a small maintenance step rather than a major purchase.
Motorcycles Universal Blue Chain Oil Dirt Clean Brush Fits ATV Dirt Sport Street
Chain maintenance is where the blue brush earns its place. This is a new tool built with nylon bristles and an ABS plastic grip, and the three-sided bristle arrangement is designed to clean chains, sprockets, and wheels. It fits ATV, dirt, sport, and street motorcycles, which gives it a more general use than the chain or the plug. It also has the lowest listed price, so it is an easy addition to a maintenance shelf. The catch is that it only cleans; it cannot fix a worn chain, a broken link, or an ignition issue, so treat it as the prep step rather than the cure.
2005 Custom Built Motorcycles Bulldozer
A complete used bobber is a different shopping mission, and the Bulldozer fills that slot. This 2005 Custom Built Motorcycles Bulldozer is a used private-seller bobber with a 1340 cc engine, black exterior, 2,000 miles, and a clean vehicle title. The build is a Bulldozer clone with Exile Cycle parts, a 6-speed transmission, an S&S Super E carburetor, fresh fluids, and Avon Cobra Chrome tires. The main limitation is the price: it is by far the highest-priced item in this comparison, and it is a used custom machine sold by a private seller, so it is a very different purchase decision from picking up a new chain or a spark plug. If you are shopping for a ride, this is the option that fits.
Final recommendation by use case
- For a street-motorcycle chain replacement, the Vortex Racing V3 2.0 Chain is the only chain in this set and the right part when your bike needs 520RX3 sizing.
- For a Harley-Davidson street motorcycle ignition task, the CHAMP ion RA8HC is the plug that matches the need for that fitment.
- For routine chain and sprocket maintenance, the universal blue chain brush is the lowest-priced way to scrub oil and dirt before it becomes a bigger problem.
- For a complete used bobber, the 2005 Custom Built Motorcycles Bulldozer is the only full motorcycle here and the one to consider when you want a ride rather than a component.
