The Honda CB750 is widely considered the first modern superbike. When it debuted in 1969, its 736cc SOHC inline-four engine, front disc brake, and electric starter were revelations for a mass-market machine. It offered unprecedented performance and reliability, instantly making competitors' bikes seem outdated. The earliest 1969 models, known as "Sandcasts" for their unique engine case casting method, are the most sought-after by collectors due to their rarity and historical importance.
The CB750 market is diverse, spanning multiple decades and models. The SOHC K-series bikes (K0 through K8) are the archetypal classic, while the later F-series (Super Sport) offered sportier styling. In 1976, Honda introduced the CB750A, featuring a 2-speed "Hondamatic" semi-automatic transmission. While an interesting piece of engineering, the 750A is less valuable than its manual-shift siblings. The DOHC models introduced in 1979 marked a complete redesign and represent a more affordable entry into CB750 ownership.
Today, the CB750 is a cornerstone of the classic motorcycle market. An average sale price near $10,000 shows the model's broad appeal, covering everything from rider-quality later models to pristine early examples. Top-tier, low-mileage Sandcast bikes can command prices over $50,000, confirming their status as blue-chip collectibles. For most buyers, a well-sorted K-series bike from the mid-1970s offers the classic experience for a much lower investment.
Buying Tips
- Original 4-into-4 exhaust systems are very rare and expensive. Check for rust, damage, and aftermarket replacements, which reduce value.
- The SOHC engines are known for oil weeps, especially around the head gasket. Check for signs of leaks or excessive use of sealant.
- Verify the specific model, as value varies greatly. Early K0-K4 bikes are more desirable than later K5-K8 and F models. Sandcast engines have serial numbers below CB750E-1007414.
- On CB750A models, test the 2-speed Hondamatic transmission to ensure it shifts smoothly. These units are complex and parts can be difficult to source.
- Inspect the charging system. Failed stators are common on original bikes, so look for documented upgrades to modern, more reliable components.
Prices for the Honda CB750 range from under $1,000 for project bikes to over $50,000 for exceptional early 'Sandcast' models.
