Crafting a Low-Profile Customization: KAWASAKI ZRX1200/R Custom by M-TECH
M-TECH's ZRX1200/R
This ZRX1200R by m-tech of Kyoto, Japan features black parts chosen to create a cool atmosphere while maintaining the stock styling. We asked Mr. Matsumoto at the store for more details. "This ZRX is the owner's first big bike. They asked us to select the necessary parts for a low-profile customization. There are many parts available for the ZRX, which might tempt one to add more and more. Flashy parts for the ZRX abound, often leading to a fancier aesthetic, but we aimed to achieve the opposite effect. First, we changed the exhaust system, then the brakes and wheels for 'stopping,' following our store's theory. Next, we focused on the front and rear suspension for 'turning,' and adjusted the settings to match the lighter wheels. Proper adjustment is crucial when altering the suspension. Once these steps were completed, we replaced the carburetor to enhance 'running' performance. We proceeded step by step, and the owner has enjoyed the ease of riding at each stage."
The latest change at the time of the photoshoot was the swingarm, where the G-Striker was selected as it is the most flexible. Mr. Matsumoto said that in the case of the ZRX, unlike using high-grip tires in racing, a sub-frame or a too-strong rear configuration would make it difficult to ride on the street, as the front end would be pushed too hard and make it difficult to turn. He continues, "It is enough to have a chromoly right down tube." The chromoly shaft can also provide a force relief point, which is a bit of m-tech know-how. Also, they were in production for this bike at the time of the interview. Tailoring that increases the enjoyment of riding by establishing the order and adding and subtracting. Eventually, the engine will need to be overhauled, but there is no need to worry about that. Although m-tech may be associated with Suzuki's oil-cooled and racing background (and actually has a strong involvement in these activities), their work is very much in line with what is needed in a motorcycle, whether it is a supersport or naked bike, including the appearance. This can be a great reference for how to work on the ZRX.
Handle
The steering stem is made by OVER RACING, and a Yoshimura Progress Meter is added to the stock meters. The handlebar was changed to a low type.
Electrical
The turn signals have been downsized and the headlight has been converted to a yellow lens. The left and right masters are Brembo RCS.
Bodyworks
The seat has been modified to create a position that suits the owner in combination with the low type handlebar and OVER Rearsets.
Engine
The engine is currently stock, but a T-REVα was added to contribute to the ease of riding. They are considering overhauling the engine, camshafts, transmission, and other modifications.
Once the bodywork was properly completed, the carburetor was converted to a TMR-MJN 38mm diameter carburetor with a K&N filter specification.
Chassis
The Ohlins RWU forks are mounted with Brembo Axial CNC 4P calipers via m-tech's standard Cleverwolf supports (which are rigid and do not lose braking efficiency). Brembo Supersport discs were also selected.
The rear brake is Brembo GP2-CR CNC Caliper + Sunstar Works Expand Disc. The titanium bolts made by Beta Titanium are used throughout the bodywork. The exhaust system consists of Yoshimura Titanium Exhaust Pipes and a Maverick Silencer.
The front and rear wheels are forged aluminum Marchesini M7RS in 3.50-17/6.00-17 sizes, and Bridgestone S22 tires in 120/70ZR17 front and 190/55ZR17 rear. A G-Striker swingarm with Ohlins Blackline was selected.
