CUSTOM SCOOTER

Maximum Hybrid: A Supercharged Yamaha SMAX from Taiwan

Starting with a humble SMAX 155, FS-TMAX has created a mind-bending custom by grafting on parts from its siblings and adding a supercharger for good measure.

YAMAHA · SMAX 155FS-TMAX

The Taiwanese scooter tuning scene is a world unto itself, a place where creativity runs rampant and boundaries are constantly being pushed. This wild creation from FS-TMAX is a perfect example. What you're looking at began as a sensible Yamaha SMAX 155, but it has been systematically and artfully transformed into something entirely new. It's a "hybrid transplant" build, borrowing the aggressive front end of a Yamaha FORCE and the iconic tail section of a TMAX, creating a machine with a completely unique identity and a stance that means business.

Chapter 01

A New Identity From Three Yamahas

The core of this build’s visual transformation is the clever integration of bodywork from other Yamaha models. The sharp, angular face of a Yamaha FORCE was seamlessly grafted onto the SMAX frame, immediately giving it a more aggressive presence. In the rear, the tail section from the king of maxi-scooters, the TMAX, was adapted, featuring a five-piece kit from Light Master. This combination creates a silhouette that is both familiar and entirely unique. A widebody kit from Kuang Factory further exaggerates the scooter's lines, giving it a muscular, planted look that the stock SMAX could only dream of.

"It started life as a Yamaha SMAX, but now it wears the face of a FORCE and the tail of a TMAX."

Chapter 02

Forced-Induction Powerplant

Not content with a purely aesthetic exercise, FS-TMAX gave this scooter the heart of a true performance machine. Tucked into the frame is a supercharger, a modification that radically alters the 155cc engine's character. Managing the complexities of forced induction is an aRacer RC Super2 ECU, a sophisticated brain that ensures the engine runs optimally under boost. The soundtrack is provided by a stunning, custom-fabricated titanium header, with its intricate "donut" welds leading to a carbon-finished Akrapovič muffler. This isn't just for show; it's a powertrain built for serious response.

Chapter 03

A Chassis To Match The Power

All that extra power would be useless without a chassis to handle it. The suspension has been thoroughly upgraded, starting with a set of beefy MSP UF2 inverted forks up front. The rear is controlled by Shark Factory X2 HL shocks, a high-end component that offers a huge range of adjustability. To increase stability and achieve a stretched stance, the rear wheel has been pushed back 17cm with a TDS extension kit. Stopping power is equally serious, with a Brembo 484 caliper on the front and a CNC P2 caliper on the rear, all actuated by master cylinders borrowed from a TMAX for a better feel at the lever.

Chapter 04

An Obsession With The Details

A great build is defined by its details, and this SMAX is covered in them. Carbon fiber is used extensively, from the ONES front fender and backbone cover to the instrument surround and side strips. This is complemented by a host of jewel-like titanium hardware and accessories. Baphomet titanium frame plugs and footplates, an ONES titanium fuel cap, and Simota carbon mirrors with titanium arms all speak to a cost-no-object approach. Every bracket, cap, and fastener appears to have been considered, resulting in a cohesive and deeply impressive level of finish that rewards close inspection.

It blends the DNA of three different Yamaha models to create a machine that is visually aggressive, while the supercharged engine and top-tier chassis components provide performance to back up the looks. It’s a stunning example of the boundary-pushing creativity thriving in Taiwan's custom scene.
