After teasing us with some photos in January, Triumph has released full details about the new 2019 Rocket 3 TFC. Besides the switch from roman numerals and the addition of premium Triumph Factory Custom components, the limited edition 2019 Triumph Rocket 3 TFC supersizes what was already the world’s largest production motorcycle engine to a massive 2458cc displacement, claiming more than 168 hp and 163 lb-ft.
Each of the Rocket 3 TFC’s cylinders has a larger displacement than the Tiger 800’s three cylinders combined. Carbon-shielded pipes exit from each cylinder, leading toward two stacked Arrow silencers with carbon fiber end-caps.

As a Triumph Factory Custom, the Rocket 3 comes with a lot of premium carbon fiber parts. The bodywork, front fender, fly screen, drive …read more
