Triumph Street Triple S 765cc (2017-2019) Maintenance Schedule

This is the maintenance schedule with associated service intervals for the Triumph Street Triple S made from 2017-2019.

The Triumph Street Triple S 765 is the base model of the new 765 cc line. It has lower-spec brakes and suspension, and the same 765 cc inline three-cylinder engine (a triple) at its core, but it makes slightly less peak power — 111 kW (113 PS / 83 kW) at 11250 rpm.

The maintenance schedule for the Street Triple S 765 very similar to those for other motorcycles with similar engines in the Triumph Street Triple Series, like the full spec Street Triple R.

From 2020, the Street Triple S 765 seems no longer available, replaced by the Street Triple S 660.

Firstly, you need to see if you have the basic motorcycle maintenance tools — nothing shocking, just things like a paddock stand, oil filter wrench, and so on.

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.

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 off 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.
