The short version
Forecourt score
Value 50 · Insurance 68 · Theft 65
The Suzuki GSX-8S holds its value about as well as most bikes (around 30% lost over three years, against the 25-32% bike norm) and costs about average to insure (around £440/yr typical). 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.

HIGH CONFIDENCE
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.

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

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
Newish model, less established on theft lists than Yamaha MT-07 but expected to rise. Chain + disc lock 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.
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 Suzuki GSX-8S, 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.
