Triumph first introduced the world to its oversized Rocket 3 in 2004. Powered by a 2.3-liter inline-three-cylinder engine, the Rocket is basically an engine on wheels with a saddle. Now there’s a new Rocket 3 from Triumph Factory Custom , which boasts an even larger and more powerful engine. Each of them will get a numbered plaque and a sticker price of $29,000. Deliveries are slated to start in December of 2019.
