Kawasaki Z650
Kawasaki's MT-07 challenger — and the cheapest middleweight naked you can buy. 649cc parallel-twin, 67 PS, A2-restrictable, light at 187 kg. The Z650 doesn't out-spec the MT-07 anywhere meaningful, but it's £750 cheaper new — which buys a lot of upgraded suspension. Strong choice for buyers who want middleweight naked performance on the tightest budget.

The short version
Forecourt score
Value 55 · Insurance 44 · Theft 65
The Kawasaki Z650 costs about average to insure (group 10). Theft risk is moderate. It can be restricted for an A2 licence. We don't yet hold model-specific depreciation for the Kawasaki Z650; our default estimate is around 28% 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.
UK new price by year
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 2 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.
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
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
Less targeted than Yamaha MT-series but still on insurance watch-lists. Chain + disc lock advised in 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.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Kawasaki Z650, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.
Variant comparison
The budget middleweight naked. Cross-shop Yamaha MT-07 (£750 more, more character, more theft-prone), Honda CB650R (inline-four, £1.4k more), Triumph Trident 660 (more power, more refined, £1.2k more). Z650 wins on price; loses to MT-07 on residuals and character.
Known issues
- Stock suspension soft — most owners upgrade fork springs (£150)
- Chain stretch at 18-20k mi (£250)
- Regulator/rectifier on early bikes (improved 2022+)
- Fork seals at 25k mi (£120)
- Otherwise extremely reliable — proven Kawasaki twin
Strengths
- +Cheapest middleweight naked — £750 less than MT-07
- +A2-restrictable to 35kW
- +Light at 187 kg — friendly for newer riders
- +Kawasaki reliability — proven 649cc twin
- +Strong residuals on the used market
Watch-outs
- −Less power than MT-07 (67 vs 73 PS) and Trident (80 PS)
- −Stock suspension softer than rivals — upgrade money needed
- −TFT dash optional, not standard until SE trim
- −Kawasaki dealer network smaller than Yamaha/Honda

Common questions
Kawasaki Z650, answered from the data
- How much is a used Kawasaki Z650 worth?
- A 2023 Kawasaki Z650 in good condition with around 9,000 miles is worth roughly £4,950 (typical range £4,450–£5,400). 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 Kawasaki Z650 depreciate?
- We don't yet hold model-specific depreciation for the Kawasaki Z650. Our default estimate for machines of this kind is a loss of about 28% 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 Kawasaki Z650 on an A2 licence?
- Only if restricted. The Kawasaki Z650 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 Kawasaki Z650?
- Expect around £820 a year to insure a Kawasaki Z650, typically £640–£1,100. That assumes age 30, 3yrs NCB, suburban postcode. 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 Kawasaki Z650?
- The wear and failure points we track for the Kawasaki Z650 are: stock fork springs (soft) (any, £150 progressive upgrade); chain stretch (around 18-20k mi, £250); regulator/rectifier (pre-2022) (around 30k+ mi, £200). 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 Kawasaki Z650 cost to run?
- Expect around 60 mpg, about £363 a year in fuel or energy, £240 for an annual service, £320 a pair for tyres every 6,500 miles, £250 for a chain and sprockets every 19,000 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 Kawasaki Z650 likely to be stolen?
- The Kawasaki Z650 is a moderate theft target. Less targeted than Yamaha MT-series but still on insurance watch-lists. Chain + disc lock advised in London postcodes. Theft is concentrated in E, N 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.
