How much is a used Triumph Speed Twin 900 worth?

A 2023 Triumph Speed Twin 900 in good condition with around 9,000 miles is worth roughly £6,500 (typical range £5,850–£7,150). Dealer asking prices sit higher than private sales, and a full service history, no crash damage and an unbroken theft record are what hold a bike at the top of its range.

How quickly does the Triumph Speed Twin 900 depreciate?

The Triumph Speed Twin 900 loses about 24% of its value over the first three years, against a 25–32% norm for bikes and 40–50% for cars. These figures are specific to this model rather than a shared default, though they remain indicative estimates rather than a measured sample of sale prices.

Can you ride the Triumph Speed Twin 900 on an A2 licence?

Only if restricted. The Triumph Speed Twin 900 is an unrestricted category A machine as sold, but it can be restricted to A2 limits. A restricted example is worth checking carefully — the paperwork matters to insurers, and a derestricted bike on an A2 licence is not road legal.

How much does it cost to insure a Triumph Speed Twin 900?

Expect around £680 a year to insure a Triumph Speed Twin 900, typically £500–£1,050. That assumes Age 30, 3yrs NCB, suburban postcode. Modern-classics attract slightly older riders, which keeps premiums lower than sports nakeds. It sits in motorcycle insurance group 10 of 17. Bike premiums move far more on licence tier, rider age and postcode than car premiums do, so treat this as a starting point rather than a quote.

What goes wrong on a used Triumph Speed Twin 900?

The wear and failure points we track for the Triumph Speed Twin 900 are: throttle body sync drift (around 15k-25k mi, £90); cam chain tensioner (around 25k-35k mi, £180); stator (around 35k-50k mi, £280). We don't publish a reliability score for bikes — the MOT dataset behind our car scores doesn't support one at model level — so treat these as the specific things to inspect rather than a verdict. A full service history and a fresh MOT without advisories remain the best protection.

What does a Triumph Speed Twin 900 cost to run?

Expect around 55 mpg, about £396 a year in fuel or energy, £340 for an annual service, £250 a pair for tyres every 9,000 miles, £240 for a chain and sprockets every 15,000 miles. Figures assume 3,000 miles a year, the UK average from DfT travel and traffic statistics, and current DESNZ pump prices. The cost-of-ownership table on the profile breaks this down per year and per mile.

Is the Triumph Speed Twin 900 likely to be stolen?

The Triumph Speed Twin 900 is a moderate theft target. Triumphs are mainstream-popular and easy to ride away. Chain + ground anchor + disc lock for London postcodes. Theft is concentrated in E, N, SE postcode areas. A Thatcham-approved chain and ground anchor, a disc lock and a tracker are what insurers look for, and secure overnight storage moves a premium more than almost anything else.

Triumph Speed Twin 900

Triumph's lighter modern-classic — formerly the Street Twin, renamed Speed Twin 900 in 2023 to align with the larger Speed Twin 1200. The 900cc parallel-twin (270° crank) delivers the classic Triumph thump in a friendly, A2-restrictable package. Low 765mm seat suits shorter riders, and the chassis is balanced enough that experienced riders can still extract a smile from it. The trade-off is power — 65 PS feels modest next to its 1200cc sibling. Triumph residuals are excellent, theft risk is moderate.

Forecourt score

Value 66 · Insurance 44 · Theft 65

The Triumph Speed Twin 900 holds its value about as well as most bikes (around 24% lost over three years, against the 25-32% bike norm) and costs about average to insure (group 10). Theft risk is moderate. It can be restricted for an A2 licence.

A bike-specific blend of value retention, insurance and theft risk (weighted 40/35/25). Bikes carry no MOT reliability data, so reliability isn't scored. Higher is better.

Holding value

Bikes hold value far better than cars — typical motorcycle 3-year depreciation is 25–32%, against cars' 40–50%. Some bikes (Hayabusa, Gold Wing, classic Z1000) actually appreciate in the 7–15 year zone as cult demand outstrips supply.

How we estimate this

These figures are specific to this model rather than a shared default, but they are indicative estimates and not yet derived from a recorded sample of UK sale prices. Bike residuals depend heavily on theft history, service-stamp count and crash-damage signatures. Figures assume a clean, fully-stamped example.

What it costs to own

Over

Indicative running costs at 3,000 miles a year — the UK average from DfT travel and traffic statistics. Chain-drive bikes carry a chain/sprocket consumable line; tax (typically £25–£100/yr) and depreciation are excluded — see the section above for value retention.

MOT£90

Fuel / energy£1,188

Service costs assume independent specialist labour and OE parts. Tyre intervals reflect typical UK road riding — track-day usage burns through rear tyres in <2,000 miles. Fuel uses the variant MPG at the current DESNZ pump price of £1.60/L (week commencing 03/08/2026). Electric bikes are costed from battery capacity and published range at the current domestic electricity price; where a bike has no published range we show no energy line rather than guess. Lower-mileage riders see proportionally lower totals; higher-mileage commuters pay roughly linearly more.

Estimated insurance

How we estimate this

Premiums combine licence tier, rider age, no-claims bonus and a risk-profile multiplier on top of a bike-specific baseline. Bike insurance is materially more sensitive to licence tier (CBT / A1 / A2 / A) than car insurance, and young riders pay considerably more than older riders even on the same machine. Always get individual quotes before buying.

Theft risk

Bike-specific · Met Police + insurance reporting

UK bike theft rates are an order of magnitude higher than car theft. Nakeds and supersports lose more to professional gangs; large adventure bikes and tourers are statistically much safer.

Theft risk score · 1 to 4

Medium risk

Theft hotspot postcodes

ENSE

Postcode prefixes only; full London hot zone runs across E, N, NW, SE, SW, W boroughs depending on the model.

What this means for you

Triumphs are mainstream-popular and easy to ride away. Chain + ground anchor + disc lock for London postcodes.

How we set this band

Bands derived from Met Police bike-theft reporting (most-stolen lists) cross-referenced with insurance industry underwriting data. Model + postcode are the two biggest factors in motorcycle theft risk in the UK, materially more than vehicle value.

What goes wrong

5 known issues · sorted by severity

Documented failure modes from UK owner forums, dealer service bulletins, and aggregated mechanic feedback. Mileages are approximate — different riders see different intervals depending on use and maintenance. Always address "high"-severity items before resale.

How we score severity

High — strands the bike or causes consequential damage if left. Medium — service item that affects ride quality or risks failure. Low — cosmetic or minor inconvenience. Costs are independent-specialist UK rates for parts and labour together; main dealer prices typically run 30–50% higher.
