[Custom Bike Introduction] Advantage Ninja ZX-4RR "Equipped with Original Parts Based on Unique Philosophy"

The renowned custom parts manufacturer, ADVANTAGE, has created a custom machine based on the Kawasaki Ninja ZX-4RR, a 400cc, inline-four supersport. This build focuses on enhancing functionality, particularly in the suspension, braking system, and riding position, all guided by ADVANTAGE's unique design philosophy.

Uncompromising Performance in Suspension and Braking Systems

ADVANTAGE Ninja ZX-4RR

ADVANTAGE | ZX-4RR

This demo bike is equipped with ADVANTAGE's magnesium forged wheels, the "EXACT RACING10," significantly enhancing its agility through drastic weight reduction. For tires, the latest model from Bridgestone, the "BATTLAX HYPERSPORT S23," has been chosen.

The braking system features ADVANTAGE's "DIRECT DRIVE RACING DISC," which is thicker than the stock version at 4.5mm. Paired with NISSIN monobloc calipers, which weigh just 0.971kg including pads, this setup achieves both powerful stopping force and delicate control.

Both front and rear wheels are ADVANTAGE magnesium forged wheels, "EXACT RACING10".

The rear wheel is 5.5 inches wide compared to the stock 4.5 inches, fitted with a 180/55ZR17 BS S23 tire, which is two sizes wider.

The "ADVANTAGE DIRECT DRIVE RACING DISC" is thicker than the stock version. The caliper is a "NISSIN 4POT RADIALFIT Monobloc Caliper".

Riding Steps Reflecting a Unique Philosophy

The "Riding Steps" developed by ADVANTAGE feature four adjustable positions based on the stock position. To address a lack of rigidity and ensure the rider can firmly plant their feet, the design deliberately avoids extreme changes from the stock position.

A rear brake master cylinder is also included. The "NISSIN Racing Master," with its integrated fluid tank, eliminates external hoses and separate reservoirs, reducing the risk of damage or failure in a fall. It also contributes to a cleaner, more compact look around the step area. The price is 130,000 yen (excluding tax), and it is compatible with the ZX-25R/RR, which shares the same chassis.

ADVANTAGE Riding Steps for the ZX-4RR. Four positions can be selected, but the step movement is minimized: 0mm BACK / 0mm UP, 12mm BACK / 0mm UP, 0mm BACK / 12mm UP, and 12mm BACK / 12mm UP.

Designed to eliminate the feeling of the stock steps flexing at the base when bracing, a common complaint. The pedals also feature a crisp and solid operation.

Riding Steps are available in two colors: silver and black. The kit also includes an integrated rear master cylinder.

The master cylinder has been changed to a φ19 radial master (short lever & smoke tank specification), achieving exquisite brake feel.
