The Triumph Street Triple is a series of standard (naked) motorcycles manufactured by the British company Triumph Motorcycles Ltd. Introduced in 2007 as a successor to the Triumph Daytona 675 in the road‑oriented segment, the Street Triple line has undergone multiple revisions and engine enlargements while retaining a focus on agile handling, moderate weight, and a mid‑range power delivery.

Engine and performance

- Street Triple 660 (2015–2020): 660 cc version of the same triple, retuned for slightly lower peak power (≈95 hp) with a broader torque curve, aimed at improving rideability in everyday traffic.
- Street Triple R (2013–2020): Higher‑spec variant of the 675 cc engine with revised intake, exhaust, and ECU mapping, delivering around 105 hp (78 kW) and 71 Nm of torque.

Chassis and dimensions
All Street Triple models share a steel tubular frame with a rear subframe of aluminum alloy. Front suspension is typically a 43 mm upside‑down (USD) fork; rear suspension employs a monoshock with linkage. Wheelbase ranges from 1 452 mm to 1 460 mm, and dry weight lies between 166 kg and 176 kg, depending on the version and market specifications.
Design evolution
- 2007–2012: Conventional naked styling with a modestly raked front fork and a twin‑headlamp arrangement.
- 2013 redesign: Sharper angular bodywork, single LED headlamp, and revised ergonomics for a sportier riding position.
- 2017 facelift: Updated graphics, LED daytime running lights, and an optional TFT instrument cluster.
- 2021 refresh (Street Triple RS): Full fairing‑style headlamp cluster, larger 19‑inch front wheel, and a revised swingarm to accommodate the larger engine.
Market positioning
The Street Triple occupies a niche between entry‑level naked motorcycles (e.g., Yamaha MT‑07) and higher‑displacement sport bikes (e.g., Ducati Monster 1200). It is marketed for riders seeking a balance of performance, everyday usability, and relatively lightweight handling.
Reception and awards
The model has received numerous industry accolades, including Motorcycle News “Bike of the Year” (2007) and the International Bike of the Year award (2013) for its R variant. Reviewers frequently cite its tractable power delivery, chassis agility, and distinctive three‑cylinder character.
