A bit of history.
20 years ago Triumph introduced the
Speed Triple. It was a smash hit. In the meantime the company was going through turbulent time. The company's sportbike division was a mess and the company really didn't have an identifiable, modern product besides the Speed Triple.
For the 2006 MY, Triumph introduced the Daytona 675. A svelte, ultra-modern sportbike that features a three-cylinder motor ... a departure from the four-cylinder motors it had featured in the Daytona 600 and 650.
In 2007, Triumph stripped the Daytona of its fairings, attached a new subframe and built a wonderful naked bike, the Street Triple. The Street Triple has been a smash success for the Hinkley-based manufacturer.
Now, rumours are rampant that Triumph is readying an entirely
new range of Street Triples to replace the Street Triple/Street Triple R/Street Triple Rx.
Rumours suggest that the all-new bike will feature a fresh, 800cc three-cylinder engine based on that recently incorporated into the Tiger 800.
Rumours suggest :
-new 800cc engine
-four-model range
-different fairing variations
-TFT clocks, multiple rider modes and rider-aides
-updated styling
