1970s Kawasaki H2 Mach IV 750 (H2/H2A/H2B/H2C) Valuation Report

Date: August 2025

Historical Overview

Kawasaki’s H2 “Mach IV” 750cc two-stroke triple (1972–1975) defined the 1970s superbike shock factor. The early H2 (1972) and H2A (1973) are the rawest and most coveted; later H2B (1974) and H2C (1975) brought incremental chassis and tuning refinements. UK collectors prioritise originality (paint, pipes, airbox), matching numbers, and documented restorations. Exceptional, correctly finished examples achieve strong results at UK auctions.

Notes: Ranges reflect verified UK results from late-2023 to mid-2025 where available. Early H2/H2A normally command a premium over H2B/H2C in like-for-like condition. Publicly recorded “project” hammer prices are limited in the last 18 months; where projects appear, many transact privately or without disclosed prices.

Value Influencing Factors

• Originality & matching numbers: Correct paint codes, pipes/airbox, UK-appropriate lighting, and matching frame/engine numbers carry premiums.
• Restoration quality: Documented professional rebuilds with period-correct details outperform show-polish with incorrect parts.
• Variant & year: Early H2/H2A (’72–’73) are typically the strongest; later H2B/H2C still sell well if highly original.
• Provenance & paperwork: History files, import/NOVA/V5C, and mileage evidence add confidence.
• Market timing: Spring–summer auctions remain strongest; winter can soften rider prices.

Conclusion

In the UK market, a correctly restored H2/H2A typically achieves £16.5k–£21k, with tidy roadworthy examples around £12.5k–£17.5k. Later H2B/H2C restored bikes commonly realise £12.5k–£16k, with presentable riders £9.5k–£13k. Market trend: pricing is stable to firm versus 2023–2024, with best-of-breed, matching-numbers restorations continuing to attract strong bids.
