The Street Triple was launched by Triumph in 2007 when it established the benchmark for the middle weight bikes as one of the most agile and light handling bikes. It was distinct with a three cylinder engine, aggressive looks and thrilling power delivery.

The new 2020 bike has got a jump in its displacement to 765 cc triple engine which is Euro 5 compliant. The bike is powered by a liquid cooled engine with a DOHC and 12 valves and mulitpoint sequential electronic fuel injection and electronic throttle. It produces 123 PS of power at 11,750 rpm which is 9% more than the outgoing bike. The Triumph Street Triple also produces 79 N-m of torque at 9,350 rpm which is again a jump of 9% over the predecessor. The exhaust has been redesigned to be more free flowing allowing for a crisper engine note. The power and torque is transmitted through a wet, multi-plate, slip assisted clutch and 6 speed gearbox to the rear wheel.

The front frame is made from Aluminium beam with spar while the rear is a two piece high pressure die cast. It has a twin sided Aluminium allow swingarm. The front suspension comprises Showa 41 mm upside down big piston forks (BPF), Adjustable compression damping, rebound damping and preload adjustment, while the rear has Ohlins STX40 fully-adjustable piggyback reservoir RSU. 120/70 ZR17 tyres do duty at the front and 180/55 ZR17 at the rear.

Stopping power is provided by Twin 310 mm floating discs, Brembo M50 4-piston radial monobloc calipers at the front and Single 220 mm disc, Brembo single piston caliper, switchable ABS at the rear. The bike weigh 166 kg dry and has a fuel capacity of 17.4 litres giving it a range of 335 km between refills.

The bike has new distinctive and striking twin LED headlights with Daytime Running Lights. However it maintains the bug eyed look from the previous generation bikes. The new Street Triple RS now has all new bodywork, which is more angular, more sporty, and with much cleaner lines. The new fly screen and air intake are now more pronounced, echoing the shape of the new DRL, plus the side panels, rear unit, seat cowl and belly pan are all new and distinctly different. It has new mirrors, new branded handlebar clamp and new Titanium Silver main frame. Information about the bike is exchanged with the rider through a TFT display with enhanced functionality in four different styles, and four different colours. The TFT screen angle can be adjusted for optimum visibility to suit rider height. Triumph has installed the bike with a MyTriumph connectivity  system which delivers GoPro interaction,
turn-by-turn navigation and music and phone operation. There are five riding modes, Road, Rain, Sport, Track, and Rider configurable. These modes adjust throttle response, ABS and traction control settings, and can easily be selected whilst riding. Rain mode restricts power to 100PS for enhanced safety and control.
