1970s Triumph T90 Tiger 350 cc Valuation Report

Date: September 2025

Historical Overview

The Triumph T90 Tiger 350 cc was a smaller-capacity twin aimed at riders who wanted Triumph style and handling without the insurance or running costs of the larger 500 and 650 models. Built until the early 1970s, the T90 was a revvier, sportier version of the Triumph 3TA. Today, surviving examples are rarer than their bigger siblings, and interest has grown among collectors seeking unusual smaller-capacity British classics.

UK Valuation Summary (by condition)

Condition	Estimated Value (GBP)	Example External Source (plain text)
Project / Restoration Non-running or incomplete; usually requiring full rebuild.	£2,200 – £3,000	eBay UK — tired T90 projects £2.4–2.8k. Car & Classic — occasional barn finds offered ~£3k.
Roadworthy / Presentable Running, MOT’d examples; some age-related wear and common period mods.	£3,800 – £5,200	H&H Classics — 1971 T90 sold £4,600 (Jul 2023). Car & Classic listings £4–5k.

Notes: The T90 is less powerful than its 500 and 650 siblings, but rarity and originality now underpin its values. Projects remain affordable, while restored bikes fetch strong premiums due to low survival rates. As with all Triumphs, matching numbers and factory-correct details are key value drivers.

Value Influencing Factors

Rarity: Fewer T90s survived compared to Bonnevilles or Tigers, adding collector appeal.
Originality: OEM tank, paint, mudguards and silencers critical for top-end pricing.
Mileage & condition: Low-mileage survivors outperform high-use restorations.
Documentation: UK registration, V5C and service history strengthen demand.
Market trends: Smaller-capacity classics gaining momentum in UK auctions and classifieds.

As of September 2025, UK Triumph T90 Tiger 350 cc values typically fall around £2.2–3k for projects, £3.8–5.2k for roadworthy riders, and £5.8–7.5k for restored or excellent examples.
