Heritage and Philosophy: Racing Pedigree vs Accessible Excellence
Street Triple RS: The Supersport Killer
The Street Triple lineage traces back to 2007 when Triumph created the original by removing fairings from the Daytona 675 sportbike, creating the archetypal modern naked motorcycle. The current Street Triple RS represents the pinnacle of this evolution—a sophisticated, technology-laden machine incorporating Moto2 racing engine development, premium components, and comprehensive electronics.
The RS embodies Triumph’s performance philosophy at its finest—delivering supersport-level performance with naked bike practicality, wrapped in premium components and cutting-edge technology. It’s designed for experienced riders who want track-day capability, advanced electronics, and the finest components without compromising everyday usability.
Triumph targets serious enthusiasts—riders who appreciate motorcycle engineering at its finest, who value premium components and sophisticated technology, and who’re willing to pay significant premiums for the best Triumph offers. The RS appeals to riders who’ve progressed beyond entry-level machines and want Triumph’s performance flagship.
Trident 660: The Everyday Icon
The Trident 660, launched in 2021, represents Triumph’s strategic entry into the accessible middleweight segment—a market dominated by Japanese manufacturers for decades. The Trident emphasizes value, accessibility, and everyday usability rather than outright performance or premium positioning. It’s Triumph’s answer to the Yamaha MT-07, Kawasaki Z650, and similar affordable middleweights.
The Trident embodies Triumph’s mission to attract new riders to the brand—delivering genuine Triumph character, quality, and performance at prices competing directly with Japanese alternatives. It’s designed for newer riders, returning enthusiasts, or experienced riders wanting uncomplicated, fun motorcycles for daily use.
Triumph targets practical buyers—riders transitioning from smaller bikes, budget-conscious enthusiasts, or experienced riders wanting simple, enjoyable motorcycles without complexity or premium costs. The Trident brings Triumph ownership to buyers previously priced out by the brand’s premium positioning.
