In today’s market, a 1981 Honda CB900 Custom typically trades in the range of about $5,000 to $12,000, depending on condition and originality. Exceptional, fully original, or expertly restored examples can push beyond that range.
The 1981 CB900 Custom (often referred to as the CB900C) is a mid‑size vintage Honda cruiser from the early 1980s. Like many bikes from that era, value depends as much on provenance and presentation as on mechanical function, and regional demand can swing prices by several thousand dollars.

How price bands break down by condition
Prices vary by condition; the following bands reflect typical recent listings and sale data from online marketplaces and private sales.
- Concours/Original (excellent, all-original, well-documented): 12,000–15,000+ USD
- Excellent/original with minor wear or recent professional service: 9,000–12,000 USD
- Very good/restored to factory specs with quality work: 7,000–9,000 USD
- Good condition with cosmetic wear but running: 5,000–7,000 USD
- Project or non-running/needs significant work: under 3,000 USD
These ranges are approximate and strongly influenced by local demand, originality, and how well the bike has been maintained or restored. Buyer and seller sentiment on platforms like auction sites can shift momentum.
What affects value
Key value determinants
Several factors determine where a CB900C lands on the price spectrum. The most important are originality, condition, and documentation.
- Original paint and chrome quality
- Matching engine and frame numbers, and overall mechanical integrity
- Complete and verifiable maintenance history
- Provenance and documentation (service records, manuals, receipts)
- Extent and quality of restoration (stock vs. period-correct vs. modern upgrades)
- Odometer mileage and ride history
- Color and cosmetic presentation (tank decals, seat, chrome)
- Location and buyer demand (collectors vs. daily riders)
In practice, a bike with strong originality and few faults will attract higher offers than one that has been heavily modified or shows rust and hidden issues.
