What a 1984 Honda Nighthawk Is Worth in 2025

In today’s market, a 1984 Honda Nighthawk typically sells for $1,500–$6,500 depending on the specific model and condition, with the collectible CB700SC “Nighthawk S” commanding the most: rider-quality examples are often $3,500–$5,500, very clean ones $5,500–$7,000+, and exceptional, low-mileage bikes can push past $7,500. The more common CB450SC usually falls between $1,800–$3,000 for a decent rider, while the CB650SC tends to bring $2,500–$4,500. Prices vary by originality, mileage, maintenance history, and region.

Which 1984 Nighthawk do you have?

Honda sold several Nighthawk variants in 1984, and their values differ. Identifying your exact model is the first step, as displacement and trim significantly influence demand.

• CB450SC (Nighthawk 450): Parallel-twin, chain drive, light and approachable; common and affordable.
• CB650SC (Nighthawk 650): Inline-four, shaft drive; middleweight UJM with broad appeal.
• CB700SC (Nighthawk S): Inline-four, shaft drive; the sportier, tariff-era “S” model built to sidestep the period’s U.S. import tariff—most collectible of the trio.

If you’re unsure, check the VIN sticker on the steering head and engine stampings to confirm displacement and model code; styling cues (paint schemes, wheels, exhausts) can also help differentiate them.

Current value ranges (USD) by model and condition

The following ranges reflect typical U.S. sale prices observed in 2023–2025 across online marketplaces, auctions, and dealer listings. Actual transaction prices depend on local demand and the specifics of each bike.

• CB450SC (1984)
  

  • Project/non-running: $700–$1,200
  • Rider-quality (sound, average cosmetics): $1,800–$3,000
  • Very clean/original, <15k miles: $2,800–$3,800
  • Exceptional/low-mileage, documented: $3,800–$4,500

• CB650SC (1984)
  

  • Project/non-running: $900–$1,500
  • Rider-quality: $2,500–$3,500
  • Very clean/original: $3,500–$4,500
  • Exceptional/low-mileage: $4,500–$5,500

• CB700SC “Nighthawk S” (1984)
  

  • Project/non-running: $1,200–$2,000
  • Rider-quality: $3,500–$4,500
  • Very clean/original: $4,500–$6,500
  • Exceptional/low-mileage or fully restored: $6,500–$8,000+

Expect asking prices to run 10–20% above typical closing numbers; patient buyers and well-presented, documented bikes tend to meet near the middle of these bands.

What moves the price up or down

Several tangible factors consistently influence what a 1984 Nighthawk will bring on the open market.

• Condition: Original paint, straight bodywork, clean fasteners, and fresh consumables can swing value by thousands.
• Mileage and documentation: Sub-10k miles and maintenance records (valve checks, brake work, tire dates) materially increase confidence and price.
• Originality: Stock exhausts, airboxes, and turn signals are prized; heavy “customs” usually sell for less unless exceptionally executed.
• Running status: A cold-starting, leak-free, fully functional bike is much easier to sell at the top of its range.
• Regional demand/seasonality: Spring and early summer bring stronger prices; urban and Sun Belt markets often pay a premium.
• Model-specific desirability: The CB700SC’s styling and tariff-era story boost collectibility versus the 450 and 650.

Sellers who present verifiable service history and keep bikes close to stock typically see quicker sales and stronger offers.

How to estimate your specific bike’s value

A structured approach helps you anchor an asking or offer price to the current market rather than list-price wishful thinking.

1. Confirm the exact model and year from the VIN and engine stamps.
2. Document condition: high-res photos, cold-start video, compression or leak-down numbers if possible, and date codes for tires/hoses.
3. Collect comps: Search recent sold listings (not just asks) on eBay, cycle classifieds, auction sites, and local marketplaces.
4. Adjust for differences: Add value for originality, low miles, and service records; subtract for cosmetic issues, leaks, and overdue maintenance.
5. Price within the band: Aim mid-range for average riders, top quartile for clean/original with records, bottom for projects.

Revisit comps just before listing or purchasing; vintage motorcycle prices can shift seasonally and with regional supply.

Recent market observations (2023–2025)

Across U.S. and Canadian listings, rider-condition CB700SCs have held steady or inched up, reflecting demand for 1980s sport standards. Clean CB650SCs have seen modest appreciation, while CB450SCs remain entry-level classics with abundant supply. Highly original, low-mileage examples of any variant continue to outperform average bikes.

Ownership and recommissioning costs to factor in

Accounting for near-term maintenance helps you avoid overpaying for a bargain that needs immediate work.

• Tires and tubes (age-out at ~5–7 years): $250–$450 installed
• Brake system refresh (pads, fluid, hoses if original): $150–$400; more with stainless lines
• Carburetor service/sync: $200–$500 depending on shop rates
• Fluids, filters, battery: $150–$300
• Chain/sprockets (CB450SC): $180–$350; shaft-drive models avoid this cost
• Cosmetic correction (seat cover, decals, paint): $100–$1,000+ based on scope

A non-running “cheap” bike can quickly equal or exceed the price of a maintained rider once recommissioned, so adjust offers accordingly.

Regional notes

Values quoted here are U.S.-centric. In Canada, convert to CAD and expect a slightly tighter supply; clean CB700SCs can fetch a premium. In the U.K. and EU, 1980s Japanese standards see varied demand; shipping/import costs and fewer local comps can widen price spreads.

Bottom line

Most 1984 Nighthawks trade between $1,500 and $6,500, with the CB700SC “S” at the top of the range and truly exceptional examples exceeding it. Identify your model, document condition, and anchor your price to recent sold comps and maintenance needs for the most accurate valuation.
