Triumph Moto2 765

  • The 2020 Triumph Street Triple RS was launched today at the 2019 Shell Malaysia Motorcycle Grand Prix.

  • It features many revisions and updates.

  • It is now lighter and more powerful.

The much-awaited 2020 Triumph Street Triple RS was launched today at the 2019 Shell Malaysia Motorcycle Grand Prix.

The 2017 models was the most fun motorcycle we’ve ever tested and we wondered even back then how could Triumph possible make it even better. So kudos to the Hinckley based manufacturer in finding ways to make an already great bike greater.

Some of the lessons learned in Moto2 as exclusive engine suppliers were applied to the 2020 ST RS. As we’ve published before, the Triumph Moto2 engines were derived from the standard engine from the 2017 ST RS. From there it was developed only very lightly by Extern Pro.

The results were staggering. Records fell one by one and a Triumph-engined Moto2 bike hit more than 300 km/h at Mugello earlier this year. It was the first a Moto2 bike ever to hit the triple-ton. Then another three bikes went more than 300 km/h at Philip Island, Australia.

Championship organiser and promoter Dorna had wanted a series with closer racing and Triumph’s Moto2 engine delivered the show. The 2019 Moto2 championship is still open with two races to go.

Highlights of the 2020 Triumph Street Triple RS:
  • Revisions to the engine boost power by 9%, despite having 2 catalytic converters.
  • Power is up to 121 bhp and 77.3 Nm of torque, up from 116 bhp and 76 Nm.

  • Engine response tuned to provide fatter mid-range power and torque.
  • More responsive throttle.

  • Smoother powerband results from new exhaust cam.
  • High-precision machining of the crankshaft, clutch and counterbalancer.

  • Bi-directional quickshift for up and down shifts.
  • 41 mm fully-adjustable Showa forks and Öhlins rear mono shock retained.

  • Braking handled by the awesome Brembo monobloc calipers up front, with revised master cylinder.

  • New TFT screen with Bluetooth connectivity for phone and multimedia functions.
  • TFT screen can also pair with and control GoPro action camera.

  • 5 riding modes are provided: Track, Sport, Road, Rain and rider customizable.
  • New bodywork (or lack of it) — everything unneeded was pared away.

  • New “eagle-eyed” LED headlamps with Daylight Running Lights (DRL).

  • New design rear seat.
  • The result of the revisions results in a bike that weights just 166 kg dry.
  • That’s the best power-to-weight ration in its category.

No price was given at the moment, as the bike will only be available from January 2020 onwards. But you can already view at Triumph Motorcycles Malaysia.

  • More secrets of Triumph’s 765cc triple Moto2 engine has come to light.

  • The race engine is mostly stock.

  • The new engine will power Moto2 bikes from 2019.

In case you missed the news or have just arrived from another galaxy, you would pretty be much aware of Triumph supplying engines to the Moto2 class next year. The engine is the 765 triple based on the one powering the new Street Triple 765.

Before we proceed further, please allow us to share that the Street Triple 765 (especially the RS variant) is the most fun motorcycle we’ve ever tested, credit in part to that new engine.

Okay, we’ll leave it at that.

Triumph had revealed the third and completed engine at the British GP a couple of weeks ago. Fitted to modified Daytona chassis, the bike made a parade lap while members of the British media were given the opportunity to ride the bike. (Yes, we are green with envy; even The Hulk is less green.)

Every single journalist reported huge power in terms of acceleration and flexibility (availability of power anywhere in the rev range).

But what makes the engine tick? Surely you wonder.

Speaking to MCN, Steve Sargent, Triumph’s Chief Product Officer revealed, “We needed to get more power and torque and this was done by increasing the revs and reducing inertia. A standard 765 makes 123 bhp (in the Street Triple RS) and we’re pushing this to 135 bhp and about 80 Nm.”

Wait, only 135 bhp? You ask. Remember that Moto2 took over from 250cc two-strokers that produced on 80 to 90 bhp.

He continued, “A lot of this comes from the cylinder head. We’ve worked with the ports to increase gas flow and put in titanium valves and race valve spring to reduce flutter (valve float) at high RPM.”

What is “flutter” or “valve float”? It basically describes what happens when the valves do not follow the cam lobes effectively at high engine speeds. This is one reason why an engine’s maximum power is limited. MotoGP engineers, except for Ducati, combat this by using pneumatic valve springs.

“To reduce inertia, we did simple things like removing the starter motor and starter gears. It (the race engine) also has a race-kit alternator as the race bike has much less demand for electrical power and a lighter, fully-adjustable slipper clutch.”

“We’ve also changed the gearbox ratios. The first and second are both taller now and bring the rest of the ratios closer together.”

“Another new casting is the right-hand crankcase and clutch cover. The separate cover for the clutch allows teams easier access to the tuneable slipper clutch.”

Apart from those minor upgrades, the 765 Moto2 engine is surprisingly stock! The pistons, crankshaft, conrods, cams, main engine cases and air box are all the same as the standard bike’s!

The modifications bring the rev limit from 12,650 RPM to 14,000 RPM for more power and overrev in the corners. The 2019 Moto2 bikes will also receive a new Magneti Marelli ECU which features traction control for the first time in the championship. Besides TC, the ECU also allows for launch control and quickshifter with autoblipper.

“We’re running standard rods, standard cams, standard pistons and a standard crank. All of these parts are good enough for the higher sustained rpm and mean that the engine is affordable.

“The engines will be built and maintained by ExternPro, who built all the Honda Moto2 engines previously. We will shop them a kit of parts for each engine, they build it up, dyno test it and hand it to each team. Each (engine) will do three weekends of racing before it’s rebuilt.”Secrets of the Triumph 765cc Moto2 Engine Revealed
