Triumph Street Triple S (765) Service Intervals
Overall, the 765 cc Triumph Street Triple S has 6 000 mile / 10 000 km or annual service intervals, similar to its higher-spec siblings.
At every service, change the oil and filter, and do a number of checks shown below in the service schedule.
Every 12000 miles / 20000 km, change the spark plugs and the air filter, and check the valve clearances.
Even if the Street Triple S isn’t the highest-spec of the range, you’re still likely to ride it aggressively! Thus, regularly attend to its drive chain’s lubrication condition and tension.
You also need to regularly service the brake fluid and the coolant.
Triumph also recommends changing fork oil every 24000 miles / 40000 km.
What you need to service the Triumph Street Triple S 765
The following is a list of specific consumables for the Triumph Street Triple series of motorcycles.
|Part||Street Triple S 765 Spec|
|Engine oil||The manual suggests semi or fully synthetic 10W/40 or 10W/50 motorcycle engine oil which meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries.|
|Oil filter||Replace the oil filter every time you change the oil. Use Triumph part number T1218001. You can also use HifloFiltro part HF204RC.|
|Spark plugs||Use NGK spark plugs with code CR9EIA9. Make sure they’re gapped to 0.9mm with an appropriate spark plug gap tool.|
|Air filter||Use Triumph part number T2200987 or K&N equivalent part TB-6713.|
|Coolant||Triumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. Zerex G05 is a HOAT coolant that meets this spec.|
|Brake pads||Front: EBC part FA226HH (you need two sets) — Note, these are different to the RS’ pads|
Rear: EBC part FA213HH (just need one set) — Same as the RS

Chain maintenance is an important part of maintaining any chain-driven motorcycle, especially sporty ones whose chains may undergo significant stress.
Triumph recommends the following chain maintenance schedule for your Triumph Street Triple S.
Triumph recommends you lubricate your chain and check the wear periodically according to the following schedule.
|Drive chain – lubricate||200 miles (300 km)|
|Drive chain – wear check||500 miles (800 km)|
You also need to regularly check the slack of the chain per the schedule.
How to check chain slack on a Triumph motorcycle
Every brand of motorcycle measures chain slack differently. For Triumph, slack is the free vertical movement of the center part of the bottom chain segment.
- You need a ruler (or tape measure) and nitrile gloves or a rag (to avoid getting grease on your hands)
- Put the motorcycle in neutral, on a level service, and elevate the rear wheel with a stand or center stand if you have one fitted.
- Rotate the wheel and find the tightest part of the chain, in the middle.
- Use a finger to lightly push the chain up and down. Measure the deflection, which is the chain slack.
Target chain slack: 20-30 mm (0.8 – 1.2 in)
How to adjust chain slack
The procedure is similar to on many motorcycles, but of course specifics vary between brands.
You need wrenches and torque wrenches to re-tighten the rear wheel. You need a large torque wrench for the rear axle.
- Keep the motorcycle’s rear wheel elevated.
- Loosen the rear axle nut.
- Loosen the lock nuts on the left and hand side.
- Turn the adjuster bolts, usually counter-clockwise, extending the bolt “outward” to lengthen the chain and make it tighter. (Sometimes you’ll want to make it looser — in those cases, turn it clockwise / inward)
- Make sure to adjust the bolts the same amount on each side — check the markings.
- Tighten both adjuster nuts to 15 lb-ft / 20 Nm, and the rear axle nut to 81 lb-ft / 110 Nm (“very tight”).
Regular maintenance schedule
The following is the list of maintenance operations and to be done on the Street Triple S with a distance or time interval.
- There are two kinds of service interval: every a) distance or b) time period. Follow the earlier of the two intervals.
- The first break-in service should be done at 1 000 km / 600 miles or 6 months, whichever arrives sooner.
- Items marked [T] need Triumph specialist equipment.
- Camshaft timing check is at first 12K miles (20K km) service only.

About the Triumph Street Triple S 765
The Triumph Street Triple has been a long-standing mainstay of Triumph’s line-up since launched over a decade earlier as the 675cc naked roadster based on the then Daytona 675.
The Street Triple in every version is a “street”-able sportbike — revvy, but not too highly strung; powerful, but not so powerful you’ll flip your bike; high-spec, but not a race bike. The Triumph Street Triple S is another incarnation of that same spirit — comfortable, quick, and very high-quality.
In 2017, Triumph increased the displacement of their engines from 675cc to 765cc, a move that caused more than one writer to think it was just a typo (until I saw it a few times…). This is obviously for the benefit of more power, and also went along with an engine redesign to help the motorcycles meet emissions regulations.
Triumph also expanded the Street Triple range from 675 onward, releasing multiple distinct models.
To confuse things slightly, there were two versions of the Street Triple S released in 2017 — a 765cc version and the 660cc version. The 660cc version was restrictable to lower power output (35 kW / 47 hp) for compliance in Europe/Australia etc.
The Triumph Street Triple S 765 is very similar to the rest of the range — but is lower spec.
Some differences between the Street Triple S and the R and RS are that the Street Triple S has
- Front brakes — Nissin two-piston calipers, vs. the Brembo 4-piston calipers on the R and RS (in two different variations)
- Suspension — Preload-adjustable fork and shock on the Street Triple S, whereas the R and RS have fully adjustable suspension front and rear
- Instruments — the Street Triple S has an analogue + LCD display, compared to the TFT instruments on the R and RS
So the Street Triple S is much more a low-spec commuter than are the R and RS.
Still, it’s a capable bike, with an engine that produces 83 kW (111 / 113 PS hp) at 11250 rpm, you can’t say it’s a slouch. It’s the kind of bike that you can use every day without worrying about expensive parts being dinged by gravel, and then occasionally when you want to go for a blast, the suspension and brakes won’t let you down, unless you push the bike REALLY hard…
The Street Triple S was an unpopular choice as it was lower spec and wasn’t available in the 2020 revisions to the motorcycles. In the US you can only get the R and RS now. In other markets, you can only get the 660cc Street Triple S.
Reference — Manual Screenshot for the Triumph Street Triple S 765
Below is a screenshot from the original manual for the Street Triple S. It’s a little confusing — it implies that the service intervals are every 10,000 miles. But it’s 6,000 miles / 10,000 km.
The above maintenance schedule comes directly from the user’s manual for the Triumph Street Triple S, which is available on the Triumph website.
