Flakes' newest offering is a cafe racer based on the high-performance SR400, with intricately designed exterior, engine, and suspension. The exterior is characterized by a customized Peyton Place rocket cowl, featuring Cognito moto's LED projector headlight and GPS meter. The fuel tank is manufactured by Brooklands and combines with a seat modified by Motoco to create a cohesive design. Notably, the frame incorporates a looped LED taillight, resulting in a simple yet captivating rear view.


The bike utilizes SOHC Engineering's Φ90 lightweight pistons for the engine, resulting in an increased displacement of 534cc. Equipped with a Yoshimura FCR-MJN39 carburetor, the bike showcases a one-off two-pipe exhaust system and an over racing silencer, offering both striking aesthetics and superior performance. The rear suspension features Ohlins components, while WP reinforced springs are installed in the front. This bike represents a high-performance SR model that seamlessly combines traditional elements with the latest advancements in style and technology.



The front cowl is by Peyton Place, and the fuel tank is by Brooklands, making it a classic SR cafe racer combination.



A GPS multimeter from Cognito moto, a stem kit from Bore Ace, and initial adjusters from POSH provide the machine with a luxurious and modern appearance.



The displacement is 534 cc, and a Yoshimura FCR-MJN39 carburetor is chosen.

Intake & Exhaust


The two-pipe exhaust pipe is a one-off by Flakes, and Over Racing was chosen for the silencer. The suspension is by Ohlins.



The taillights are seamlessly incorporated into the curved rear frame, creating a sleek and unified look. The turn signals, supplied by Motogadget, are tastefully integrated into the seat cowl.
