Triumph Street Triple 765 S
Every consumable spec for the Triumph Street Triple 765 S, each fact sourced, dated, and shown with the source it came from. US-market reference — verify against your owner's manual.
middleweight naked triple · 2017–2021 · 765cc inline triple
Split from triumph-street-triple-765 (the Street Triple 765 RS sheet) for a genuine front brake pad difference: the S runs EBC's FA226HH shape throughout its life, never converging onto the R/RS's FA447HH. Every other consumable (oil, chain, battery, spark plugs, fluids, intervals) is shared across the whole 765 range per Triumph's own owner's handbooks — independently re-verified against this trim's own per-model specification tables, which is also where the 2020-2022 handbook's well-known '40.2 cu in (660 cc)' displacement mislabel for this trim lives (a template artifact; the oil-capacity and every other figure on that same page match the R/RS tables exactly). See triumph-street-triple-765 for the RS trim and the platform's full generation history.

Street, track, mixed
Street
- We list the manual's 'with filter change' figure — not the dry-rebuild total that circulates online. On small engines that difference is a 25% overfill.
- Pads fit calipers, not bikes. That's why one shape number covers a Hayabusa and a V-Strom — and why the same bike model can change shape mid-generation. We resolve pads by caliper and year.
Track
- After track days, shorten your oil change. How much is genuinely unsettled — manufacturers say 'adjust to your use,' not a number. Used-oil analysis is the only rigorous answer.
- A street-legal sintered or EPFA-class pad is the manufacturer-sanctioned track-day choice. Full race compounds are for when the pad is the limiting factor — and yours isn't yet.
- RBF-class fluid buys you ~80°C more fade margin when fresh — and gives most of it back within a year as it absorbs moisture. It's a consumable you change more often, not an upgrade you install once.
- For the street: silicate-free motorcycle coolant (Honda's manuals explain why — silicates chew water-pump seals). For the track: check your org's rules — most ban ethylene glycol outright; pro racing allows water only.
Mixed
Run the street specs above, then shorten the oil interval after track days — how much is genuinely unsettled, so used-oil analysis is the honest guide. If your organisation tech-inspects coolant, check its rules before a session.

Notes & corrections
Coverage gaps
Where the catalogues run out. Flagged in the open, never guessed at.
Oil spec: 2017–2019 launch generation not independently confirmed for this trim.
TOSPEC research
Only the 2020-2021 handbook edition was checked against the S-specific table this wave.
Oil capacity: 2017–2019 launch generation and 2022+ (this trim dropped from the US lineup, but EBC's catalogue implies continued non-US production through 2021 only) not independently confirmed.
TOSPEC research
No current-edition (2023+) handbook table for the S trim was found — the current handbook pairs 'Street Triple S' with 'Street Triple R - LRH' but that table's own displacement figures (765cc, 12.66:1) plus a genuinely separate 'Street Triple S 660cc' table suggest Triumph's naming has shifted; left unmapped past 2021 rather than assumed.
Spark plugs: 2017–2019 launch generation not independently confirmed.
TOSPEC research
Likely identical; left unmapped rather than assumed.
Front brake pads: 2017 launch model year not covered by this EBC row
TOSPEC research
EBC's row starts at 2018; left unmapped rather than assumed identical.
Chain & sprockets: 2017–2019 launch generation not independently confirmed.
TOSPEC research
Retailer sprocket-kit listings for the 2017-2018 launch bikes also describe 525 pitch / 118 links / 16-46, consistent with this file's 2020-2021 figures, but that wasn't cross-checked against a manual for this wave.
Battery: 2017–2019 launch generation not independently confirmed.
TOSPEC research
Likely identical; left unmapped rather than assumed.
Service intervals: 2017-2019 launch-generation interval, and any interval past 2021, not independently confirmed for this trim.
TOSPEC research
No current-edition (2023+) handbook table names the 765cc S trim directly this wave; left unmapped rather than assumed identical to the 2023+ R/RS figure (6,000 mi/12 mo).
Research notes
Context from the research trail — how a fact was pinned down.
Oil spec: This handbook's own S-trim specification table mislabels the engine as '40.2 cu in (660 cc)' with matching bore/stroke figures that don't belong to any 765 Street Triple.
TOSPEC research (source-quality note, not a fitment fact)
Almost certainly a template/copy-paste artifact shared with Triumph's Trident 660 documentation — the S trim is a 765cc engine per every other Triumph source and per this dataset's bike identity file. The current-edition handbook's S table correctly shows 765 cc / 12.66:1 compression, matching R and RS. The oil spec wording and every fluid/capacity figure on the mislabeled page match the R and RS tables exactly, so the underlying data is unaffected — only the displacement label was wrong in that one edition's PDF.
Oil capacity: Identical to the R and RS trims' 2020-2022 figures despite the table's mislabeled '660 cc' engine heading.
TOSPEC research
Re-verified directly from the S-specific table, not inherited — the numbers match the R/RS 2020-2022 variant exactly.
Front brake pads: S trim never converges onto the R/RS's FA447HH shape
EBC US #304 catalogue, p.280
Unlike the R trim (which converges onto FA447HH from 2020), the S trim keeps its own FA226HH shape throughout the years EBC lists it (2018-2021). Do not cross-shop S pads against R/RS listings.
DIY & your warranty
Doing this yourself won't void your factory warranty. The federal Magnuson-Moss Warranty Act bars a manufacturer or dealer from voiding your warranty just because you — not the dealer — did routine maintenance. To deny a claim they must prove the specific work caused the specific defect. Use spec-compliant parts and fluids, and keep your receipts.

Triumph Street Triple 765 S maintenance FAQ
How much oil does the Triumph Street Triple 765 S take?
About 3 litres with a filter change — the manufacturer's with-filter figure, not the larger dry-rebuild number that circulates online. Confirm against your owner's manual.
What oil does the Triumph Street Triple 765 S need?
It calls for 10W-40, JASO MA, API SH. A wet clutch means the JASO class matters — don't substitute an energy-conserving car oil.
What brake pads fit the Triumph Street Triple 765 S?
The front caliper (S trim (softest brake spec of the three launch trims)) takes EBC shape FA226HH. Pads are resolved by caliper and year, not by model name, so verify your caliper before you order.
How often does the Triumph Street Triple 765 S need an oil change?
Every 10,000 miles or 12 months, whichever comes first, per the manufacturer's schedule. Shorten it after track days — used-oil analysis is the only rigorous answer to how much.
