The price of a 1978 Honda CB depends on the exact model and the bike’s condition. In broad terms, a well-presented CB750 from 1978 typically sells in the mid-to-high thousands, with pristine or numbers-matching examples reaching into the high four-figures or beyond, while smaller displacement CBs from the same era usually range lower. Values can vary by region and market conditions.
To understand the question in more detail, this article examines the main 1978 CB models you’re likely to encounter, the market factors that lift or lower value, how to assess a bike you own or want to buy, and where to check current market data. The goal is to give readers a practical sense of price bands and decision points for this iconic Honda line.
Common 1978 Honda CB models and typical price ranges
The following list highlights the most commonly seen 1978 CBs and typical price bands in today’s U.S. classic-bike market. These ranges are approximate and can shift with market demand, provenance, and overall condition.
CB750 four-cylinder (the 750cc flagship of the era) — Roughly $7,000–$12,000 for a clean, running bike with good paint and chrome; $15,000–$20,000+ for concours-quality or numbers-matching, well-documented examples.
Smaller CBs in the 400–500cc class (CB500/CB400 family) — Roughly $3,000–$7,000 in solid condition; exceptional original bikes can push higher, around $7,000–$9,000.
In short, the CB750 tends to carry higher value due to its popularity and performance, while mid-sized CBs from the era command more modest, but still meaningful, price points. The exact figure for any given bike depends heavily on originality, provenance, and overall restoration quality.
What affects value the most
Market value for a 1978 Honda CB is driven by multiple interacting factors. The list below outlines the key elements that buyers and appraisers commonly consider when pricing a bike.
- Model and displacement (CB750 vs. smaller CBs) and specific variant
- Mechanical condition (engine, transmission, brakes, electrical)
- Cosmetic condition (paint, chrome, rust, dents)
- Originality and authenticity (numbers matching, original numbers on engine/frame, stock parts)
- Documentation and provenance (title history, maintenance records, receipts)
- Modifications ( aftermarket exhaust, non-original paint; judged positively or negatively depending on preference)
- Mileage and usage history (mostly original vs. refurbished)
- Location and market demand (regional interest, climate-related condition)
Because buyers prize a blend of originality and working reliability, a bike with verifiable history, correct parts, and solid running condition will typically fetch a premium over a similar bike with missing paperwork or significant wear.
How to value a specific 1978 Honda CB you own or want to buy
- Identify the exact model and year (and note any factory options or unique features).
- Assess mechanical condition (engine run, starting, charging, carburetion, brakes, suspension, and frame integrity).
- Check originality (engine and frame numbers, paint codes, original hardware, stock exhaust, and carburetors).
- Evaluate cosmetics (paint quality, chrome, rust, fading, and overall presentation).
- Review documentation and service history (maintenance records, ownership history, and any restoration work).
- Compare with current listings and price guides for similar models in similar condition.
- Consider a professional appraisal or pre-purchase inspection if you’re buying and want a precise valuation.
A careful, multi-factor assessment will give you a practical price range and a solid negotiating position, whether you’re buying, selling, or trading a 1978 Honda CB.
Where to check current market values
Reliable price data comes from a mix of guides, listings, and recent sales. The following sources are commonly used by enthusiasts and dealers to gauge current market values.
- Hagerty Price Guide for motorcycles (a widely used benchmark for classic bikes)
- NADA/Motorcycle value guides (official valuations for used bikes)
- Recent listings and sold items on marketplaces like eBay Motors and Bring a Trailer
- Classic bike forums and dealer inventories that show asking prices and sale outcomes
When valuing a specific bike, cross-check several sources, note regional price differences, and consider recent sale prices for bikes that match your model, year, and condition as closely as possible.
Summary
A 1978 Honda CB can range from a few thousand dollars to well into the five-figure zone for especially original, well-documented examples—most commonly, CB750s sit higher in value than smaller CBs from the same year. The exact price hinges on model, condition, originality, and provenance, along with regional market dynamics. Use multiple price guides, inspect the bike thoroughly, and compare with current listings to arrive at a fair assessment. For anyone considering buying, selling, or restoring a 1978 CB, a disciplined approach to evaluation will yield the best guidance and negotiation leverage.
Summary reminder: model specificity and condition drive value more than year alone; maintain documentation and originality to maximize the bike’s market appeal.
