The short version
Forecourt score
Value 50 · Insurance 63 · Theft 65
The KTM 790 Duke costs about average to insure (around £480/yr typical). Theft risk is moderate. It can be restricted for an A2 licence. We don't yet hold model-specific depreciation for the KTM 790 Duke; our default estimate is around 30% lost over three years.
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. The value pillar uses our default estimate for this bike, not a model-specific figure.

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.

Value loss by phase
Each band shows the share of original value lost during that window — not cumulative. Appreciation (green, marked +X% gained) is real for bikes that develop cult status.

How we estimate this
We don't yet hold model-specific depreciation for this bike. The figures above are our default estimate for machines of this kind, currently applied to 34 models in the catalogue — treat them as a starting point, not a measurement of this model. 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
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.

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.

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
2/4Medium risk
Medium risk
Some theft pattern, particularly in urban postcodes. Thatcham-approved chain plus disc lock recommended; secure overnight parking helps premiums.Theft hotspot postcodes
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
Premium naked with strong used demand — chain + disc lock + ground anchor essential.
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.

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.

Common questions
KTM 790 Duke, answered from the data
- How much is a used KTM 790 Duke worth?
- A 2023 KTM 790 Duke in good condition with around 9,000 miles is worth roughly £5,950 (typical range £5,350–£6,550). 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 KTM 790 Duke depreciate?
- We don't yet hold model-specific depreciation for the KTM 790 Duke. Our default estimate for machines of this kind is a loss of about 30% over three years, against a 25–32% norm for bikes generally — treat it as a starting point rather than a measurement of this model. Bikes hold value considerably better than cars, which typically lose 40–50% over the same period.
- Can you ride the KTM 790 Duke on an A2 licence?
- Only if restricted. The KTM 790 Duke 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 KTM 790 Duke?
- Expect around £480 a year to insure a KTM 790 Duke, typically £360–£680. That assumes age 32, full license, 3yrs NCB, suburban postcode. 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 KTM 790 Duke?
- The wear and failure points we track for the KTM 790 Duke are: chain & sprockets (around 8-12k mi, £220); cam chain tensioner (around 20k+ mi, £280); battery (around every 3 years, £120). 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 KTM 790 Duke cost to run?
- Expect around 50 mpg, about £436 a year in fuel or energy, £280 for an annual service, £280 a pair for tyres every 6,500 miles, £270 for a chain and sprockets every 17,000 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 KTM 790 Duke likely to be stolen?
- The KTM 790 Duke is a moderate theft target. Premium naked with strong used demand — chain + disc lock + ground anchor essential. Theft is concentrated in E, N, SE, SW 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.
