Why buy the TF 450-X from Empire
An all-new, all-Triumph 450 MX built around chassis feel, premium suspension and a full electronics suite.
- ✓KYB coil fork + Brembo standard. The KYB Air-Oil-Separate coil-spring fork and Brembo brakes give a consistent, planted feel — no air fork to chase — with the handling reviewers rate right in the mix.
- ✓Full rider-aid suite. Launch control, traction control and an up/down quickshifter standard — the kind of electronics the Japanese 450s still don’t all offer.
- ✓A real race program behind it. Developed with Ricky Carmichael and a factory SMX effort — and Empire is your local shop for parts, setup and service.
- ●Straight talk. On the dyno the TF makes about 55.7 hp — a touch under the class-best KTM 450 SX-F, which is also the aftermarket king. The Yamaha YZ450F and Honda CRF450R undercut it by ~$800 with bulletproof reliability and parts everywhere. The Triumph’s case is handling, premium spec and a fresh platform from a legacy brand.

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.
