The Kawasaki Z1000MKII was an export-only model that was released in 1978 (1979 model) and produced until 1980. It was designed as the next model after the Z1000, featuring rounded features such as a teardrop-shaped gas tank that was also used on the Z1.
The Z1000MKⅡ is a pioneering model of the “Kaku-Z” (Kawasaki’s angular Z series), which sets it apart from the Z1 and Z1000, and is still respected by a wide range of people today. The Z1000MKⅡ is produced at the Lincoln Plant (Nebraska), an American Kawasaki subsidiary. When it was released, it was very popular not only in North America but also around the world.
Like the Z1 and Z2, this car is considered a highly prized vintage model in Japan, with well-maintained vehicles fetching high prices of several million yen.

What is RCM (Radical Construction Manufacture) developed by SANCTUARY?
SANCTUARY specializes in customization and tuning of big bikes. The company’s “RCM (Radical Construction Manufacture)” is a fully custom-made complete machine production system that was launched in 2000.
RCM mainly focuses on large Japanese on-road models, restoring and tuning them using their own unique techniques, focusing on vintage models such as the Kawasaki air-cooled Z series, various Kawasaki Ninjas, Kawasaki Zephyr, Suzuki Katana, and Honda CB-F.
The original complete machine “RCM” produced by Sanctuary is different from vehicles that only have parts replaced. The key frame is reinforced after being modified. In addition, special processing is carried out to match the chassis dimensions.
The engine was installed after a full overhaul down to the smallest detail. The suspension was finished with high precision and is equipped with current high-spec items. Every section, including the electrical system, intake and exhaust system, position system, and body parts, is manufactured using a process that allows no compromise.
After the vehicle is completed, it is subjected to a 200-300km road test drive, and the key point is that a thorough system is in place, in which the vehicle is delivered only after troubleshooting any problems that are common with custom vintage cars.
Sanctuary has generously incorporated the tuning techniques it has developed through racing!
The photo shows the RCM-700 (serial number: 700), a complete bike based on the Kawasaki Z1000MKII, RCM’s 700th bike. From the engine to the suspension, it has been fully restored and customized to perfection. The bikini cowl and colorful paint job give it a style that sets it apart from the stock version, while also allowing it to perform at an extremely high level, approaching (or even exceeding) the standards of modern bikes.
Sanctuary has posted a video of the RCM-700 production process on YouTube.
① Frame processing
② Body construction, front and rear suspension and swing arm
③ Engine lower internal combustion engine processing & OZ racing wheels
④ Engine upper internal combustion engine processing & engine completion
⑤ Parts equipment incorporating racing know-how
⑥ RCM-700MK-II complete edition
The video is being released in six parts. Sanctuary has generously applied the tuning techniques it has cultivated through racing to the RCM-700. The process of gradually transforming a stock Z1000MKII into an RCM is a must-see! See the video below.

The world’s only racer-spec “air-cooled Z” aimed to be the fastest and most powerful [Sanctuary]The Sanctuary A16R Z RACER III, exhibited at the Tokyo Motorcycle Show 2022, is a one-of-a-kind race model created with the aim of being the strongest and fastest air-cooled Kawasaki Z series, in preparation for the TOT (Taste of Tsukuba) race held at Tsukuba Circuit. The KZ-series 4-cylinder DOHC 2-valve engine, which is not a 4-valve engine but is an air-cooled Z, produces 152 horsepower at the rear axle. The intake system has been tuned to mix old and new, using the ZX-10R’s original throttle body to convert to fuel injection. PHOTO/REPORT: KITA Hideaki, SANCTUARY https://www.ac-sanctuary.co.jp/
