JDM 400cc V4 era
1989-1996
Japanese-domestic-market 400cc V4 sportsbikes — VFR400 NC21/NC24/NC30/NC35 — were a cult phenomenon 1986-1996. Built for Japan's licence-class structure (under 400cc). Imported to UK as grey market post-1992. Most NC30s in UK are grey imports with adjusted speedos and full UK paperwork.
RC30-derived engineering
Race-rep philosophy
NC30 was deliberately designed to look and feel like a baby RC30 (VFR750R) — same single-sided swingarm, similar bodywork philosophy, V4 architecture (different size). The bike that proved Honda could miniaturise its WSBK platform. Cult pedigree.
Why no 400cc V4 in 2026
Licence-class change
Japan changed its licence rules — the 400cc class is no longer the licence-defining size it was in the 1990s. Combined with the cost of building V4 engines (more parts than parallel-twins), no manufacturer makes a sub-600cc V4 in 2026. The NC30's specific niche is permanently gone.
Real cost trajectory
+50% since 2018
Used NC30 in 2018: £2-3k clean. 2026: £3-5.5k clean. Significant appreciation as 90s collector market heats up. Race-spec NC30s with provenance (Steve Hislop's bike, Andy Carlile's bike) approach £15k. Honda's first foray into grey-import-cult territory.
vs CBR650R in 2026
Different bikes
CBR650R (649cc inline-four, 95bhp): modern, electronic, A2-friendly, £8,899. NC30 (399cc V4, 59bhp): analogue, race-rep, JDM-cult, £3-5.5k used. Different riders. NC30 is for collectors / 90s purists; CBR650R is for daily riders.
Rider aids count

NC30 had nothing — analogue dials, carb-fed (4× 28mm), no electronics. Pure 1990s JDM sportbike experience.
Cheapest way in
£3k
A clean NC30 from 1989-1992. 59bhp V4, single-sided swingarm, twin headlights, that classic JDM grey-import feel. Pay attention to grey-import paperwork, carb sync, reg/rec, stator condition. Ensure speedo conversion is sound. Cult bike — rising values.
