NEW KTM SX-F 450 WITH T500 by Tomasin R&D — Ride the Revolution

“Tutto il bello in questo mondo parte da un sogno.”
(All the Beauty in this World starts from a Dream.)

It’s not just a phrase, it’s the core principle that guides the company to always push itself further.

The KTM SX-F 450 WITH T500 ENGINE KIT is the idea that became a bike — without compromise.
Born from the visionary minds of the Tomasin R&D research and development department, this new “work of art” is a concept that redefines the boundaries of 500cc 2-stroke engines in modern motocross.

It’s not a reinterpretation of the past, but a projection of the future — where functionality becomes form and power becomes language.

THE ESSENCE OF DESIGN
The T500 was created to break the rules. Aggressive, sharp lines sculpted by the wind: every surface has a purpose, every element is minimal.
There’s no room for unnecessary decoration. The look is pure, essential, direct — and it radiates power even at a standstill.

THE T500 HEART: THE ENGINE — TWO-STROKE POWER REINVENTED
At the core of the concept lies an advanced 500cc two-stroke engine: integrated electronic fuel injection, electric start, dedicated electronic management with multiple maps, traction control, and launch control.
It’s the perfect fusion of lightness and control — combining the raw vitality of a two-stroke with the precision of modern technology.

“PLUG & PLAY” ARCHITECTURE
Designed to integrate seamlessly with the KTM chassis, the T500 is engineered to fit without radical modifications: no structural changes, fully reversible, and easy to install.
A “motor within a motor.”

This is the Tomasin R&D DNA: pure performance, without compromise.

THE REVOLUTION IS NOW
The KTM SX-F 450 WITH T500 engine kit doesn’t follow the rules — it writes them.
It’s a hymn to courage, experimentation, and the passion for extreme mechanics.

A motorcycle born for those who aren’t afraid to dream — and for those ready to reignite that dream.
