Webike's Opinion

Here is a "KAWASAKI ZX-4R" custom by Webike community user "Tsuji". The exhaust is a TRICK STAR Slip-On Exhaust IKAZUCHI. TRICK STAR, dedicated to producing top-quality parts with a commitment to racing specs, has channeled all of their experience into creating this silencer, which boasts the highest performance in the brand's history. The deep, resonant sound draws the rider into the world of sharp, refined riding. By eliminating the power loss caused by a sub-silencer, this exhaust achieves the power, sound, and lightweight design typical of racing exhausts.

The handlebar area has been meticulously upgraded for aggressive riding. The ACTIVE Clip-on Handlebar Kit encourages a forward-leaning posture, perfect for enjoying a sporty ride. The installation of this kit also allows for the attachement of the GALE SPEED Full Spec Master Cylinder. Ergonomically designed Domino Race Type Grips have also been equipped, along with BABYFACE Long Handlebar Ends for vibration reduction. U-KANAYA Touring Type Aluminum Billet Levers provide more efficient operation that reduces hand fatigue. Additionally, an ENDURANCE Multi Bar, which can be bolted on, was installed to mount a smartphone holder. The simple design fits compactly on the clip-on handlebars.

For the suspension, a high-end NITRON Rear Suspension Monoshock RACE (PRO) Series, specifically designed for supersport models, has been installed. Compared to the stock suspension, the road-following performance is significantly improved, and traction is greatly enhanced.
