Why buy the Rocket 3 from Empire
There is nothing else like it — the most powerful and most torque-rich production motorcycle you can buy.
- ✓The biggest engine on the planet. A 2,458cc triple — the largest-displacement production motorcycle engine ever built, making a colossal 180 hp.
- ✓More torque than anything. 166 lb-ft — more than any other production motorcycle, on tap from just off idle. Effortless, relentless roll-on in any gear.
- ✓A muscle roadster, not a copy. Shaft drive, a full color TFT, rider modes, cornering ABS and traction control — presence and technology to match the power.
- ●Straight talk. The Ducati Diavel V4 is lighter and sportier (and revs higher for its 168 hp) but makes far less torque and costs more; the Harley Low Rider ST has the American V-twin soul, bagger comfort and the deepest aftermarket, for less money; and the BMW R 18 is the value-priced retro boxer. But nothing here out-muscles the Rocket.
And the price is the price. Our advertised number already includes freight, setup and our documentation fee — only sales tax and title/registration are added.
