Triumph Street Triple 765 R
Triumph's 765cc triple naked — sharper, lighter, and more focused than Yamaha's MT-09. Same Daytona-derived engine that powers Moto2 since 2019 (120 PS in R spec, 130 in RS). At 188 kg, it's lighter than the MT-09; the Showa BPF forks and Brembo brakes are racing-grade. The Street Triple is the bike track-day instructors recommend when you've outgrown the MT-09 but aren't ready for a full litre-class.

The short version
Forecourt score
Value 58 · Insurance 13 · Theft 35
The Triumph Street Triple 765 R holds its value about as well as most bikes (around 27% lost over three years, against the 25-32% bike norm) and is expensive to insure (group 15). Theft risk is high. The main thing to check on a used one is the sprag clutch (2017-2019).
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.
3-year total

Per year
£2,346
Per mile
£0.29
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 15 of 17 (very high — superbike/cult) · 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
3/4High risk
High risk
Frequent theft target — appears regularly on UK police hot-lists, especially in London. Expect insurers to demand Thatcham chain + ground anchor + disc lock; tracker can knock 10–15% off premium.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
On insurance industry watch-lists — premium middleweight nakeds are theft targets. Thatcham chain + ground anchor essential; tracker drops premium 10-15%.
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.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Triumph Street Triple 765 R, 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 middleweight track-day weapon. Cross-shop Yamaha MT-09 (cheaper, more theft-prone, slightly less focused), KTM 890 Duke R (sharper still, ride is harder), Aprilia Tuono 660 (more touring-oriented). Street Triple R wins on chassis composure; loses to MT-09 on price.
Known issues
- Stock seat firm — touring buyers fit aftermarket (£200)
- Chain wear faster than naked twins (15-18k mi, £350)
- Sprag clutch on 2017-2019 bikes (Triumph dealer fix)
- Fork seals at 20-25k mi (£160)
- Battery every 3 years (£90)
Strengths
- +Daytona-derived 765cc triple — sharpest middleweight engine on the market
- +Lighter than MT-09 at 188 kg
- +Showa BPF forks + Brembo brakes (R spec) — racing-grade hardware
- +120 PS in R, 130 PS in RS — proper sport-naked performance
- +Track-day weapon out of the box
Watch-outs
- −More expensive than MT-09 (£700+ premium)
- −Insurance premium 15-20% higher than MT-09
- −NOT A2-restrictable in R/RS spec
- −Stock seat firm — long-distance buyers fit aftermarket
- −Theft risk high — popular target
