Why buy the Speed 400 from Empire
A genuine Triumph — the build quality, torque and style of the big bikes, at an entry price.
- ✓A real Triumph, for $5,495. The finish, switchgear and paint are a clear step above the class — this doesn’t feel like a budget bike, it feels like a Triumph.
- ✓Torque-rich and friendly. 40 hp and 27.7 lb-ft from the 398cc single, a low 31″ seat and light, confident handling — a superb first big bike that’s still fun for experienced riders around town.
- ✓Easy to own. Great fuel economy, a slip-assist clutch, ride-by-wire and traction control, with Empire here for service and the huge Triumph accessory range.
- ●Straight talk. The KTM 390 Duke makes more power (44 hp) with sharper electronics and a TFT for a few hundred more; the Royal Enfield Guerrilla 450 has a bigger engine and more torque for similar money; and the Honda CB300R undercuts it on price. The Speed 400’s edge is Triumph brand, finish and value.
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.
