    The Honda CB450K was a landmark machine for Honda. Introduced in the late 1960s, it featured a parallel-twin four-stroke engine that set new standards for performance, durability, and everyday usability. Known for its distinctive exhaust note, smooth power delivery, and robust engineering, the CB450 quickly earned a reputation as a reliable yet exciting motorcycle for riders who wanted more than basic transportation.

    With its sleek fuel tank, comfortable riding position, and timeless styling, the CB450K remains a favorite among vintage motorcycle enthusiasts today. Its blend of performance, ease of maintenance, and long-term durability helped cement its place in Honda history and made it an accessible entry point into classic motorcycle ownership — a legacy that continues decades later.

    Building a Custom CB450?

    Some parts on a custom build are not model-specific. If you’re changing handlebars, mirrors, lighting, controls, shocks, exhaust pieces, fuel line, or hardware, visit our universal and custom motorcycle parts collection.

    These parts are useful for cafe racers, brat builds, trackers, choppers, and garage-built vintage motorcycles, but they are not guaranteed to fit every bike without checking. Always compare measurements, mounting style, clearance, and product notes before ordering.


    Honda CB450 parts questions

    What model years does this Honda CB450 parts collection cover?
    This collection covers Honda CB450 models from 1965 to 1974. Because specifications changed across that span, check your year, model code, and any prior repairs against each product's listed application before ordering.
    What kinds of Honda CB450 parts are in this collection?
    You will find carburetor and fuel-system parts, engine gaskets and seals, brake components, and control cables and levers. Availability shifts as stock moves, so the live product grid above is the accurate list at any given moment.
    Are these Honda CB450 parts OEM or aftermarket?
    Both. Old Bike Barn stocks genuine OEM replacements alongside quality aftermarket parts, and each listing states which it is. OEM suits a period-correct restoration; aftermarket often costs less or offers an upgrade over the original design.
    How do I confirm a part fits my Honda CB450?
    Check the application details on the product page against your year, model code, and engine or frame number. Older machines are often not original, so confirm the part you are replacing rather than assuming factory spec. If you are unsure, contact us before ordering.
    How fast does Old Bike Barn ship?
    Orders ship from our warehouse on regular business days, and shipping is free on orders over $50 within the United States. Tracking is emailed as soon as your order leaves.
