1980s Yamaha RD350LC Valuation Report

Date: August 2025

Historical Overview

The Yamaha RD350LC, introduced in 1980, became a legend among UK two-stroke fans. The early 4L0 (1980–1982) featured liquid cooling, reed valves, and lightweight handling that made it a road and track favourite. In 1983, Yamaha introduced the RD350 YPVS (1983–1986), with a variable exhaust valve system for improved midrange power and revised styling. Both are highly desirable today, with originality and condition playing a key role in values.

UK Valuation Summary (by condition and model year)

Condition	4L0 (1980–1982)	YPVS (1983–1986)	Example External Source (non-link reference)
Project / Restoration Non-running or incomplete; may require full engine rebuild, crank seals, and cosmetic work; missing panels or clocks common.	£3,500 – £5,000	£3,000 – £4,500	eBay UK completed sales; H&H Classics – project lots
Roadworthy / Presentable Running and MOT'd; may have non-OEM paint or exhaust; generally complete and tidy but not concours.	£6,000 – £9,000	£5,000 – £8,000	Car & Classic – sold RD350 listings; Bonhams – Stafford auction
Restored / Excellent Fully restored or exceptional survivor; correct paint scheme, original parts, matching numbers, and documented history.	£10,000 – £14,000	£8,500 – £12,000	Iconic Auctioneers – sale archives; The Saleroom – multi-house results

Notes: Early UK-market 4L0 models in factory paint fetch the highest prices. YPVS models with original exhausts and bodywork are climbing steadily. Non-standard paint, aftermarket expansions, or missing airboxes typically lower value by 15–25% unless original parts are supplied.

Value Influencing Factors

• Originality: Factory paint schemes and OEM exhausts strongly affect desirability.
• Mileage: Low-mileage examples with documented history can exceed top estimates.
• Model Year: 4L0s generally command higher prices than YPVS models.
• Condition: Full restorations or unmolested survivors are the most valuable.
• Provenance: UK-supplied bikes are preferred over grey imports unless converted and documented.

Conclusion

The 1980s Yamaha RD350LC remains one of the UK’s most collectable two-strokes. Early 4L0 models lead the market, achieving £10,000–£14,000 in excellent condition, £6,000–£9,000 for usable riders, and £3,500–£5,000 for projects. YPVS models trail slightly but are rapidly appreciating, with the best examples reaching £12,000. Originality and provenance remain key to achieving top prices.
