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 holds its value about as well as most bikes (around 28% 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.

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
Phase depreciation derived from observed UK used-bike pricing — classified ads, dealer asking prices, and end-of-auction figures. Bike residuals depend heavily on theft history, service-stamp count, and crash-damage signatures. The figures here are indicative for clean, fully-stamped examples.
What it costs to own
Indicative running costs at 8,000 miles a year — the UK rider average. 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.
3-year total

Per year
£1,739
Per mile
£0.22
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 £1.45/L. Lower-mileage riders see proportionally lower totals; higher-mileage commuters pay roughly linearly more.
Estimated insurance
Group 10 of 17 (high — performance) · Comprehensive · 5 yr NCB
Indicative annual comprehensive premiums for this bike. Bike insurance is far more sensitive to licence tier and rider age than cars — pick the combination closest to your circumstances.

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
