Kawasaki has showcased two custom motorcycles, the Kawasaki Z900 RS Doremi Collection and the Kawasaki Z900 RS Bito R&D at the 2017 Tokyo Motor Show.
This motorcycle is designed by Doremi Collection, to pay homage to the racers who were active in the AMA Superbike Championships of the yore. 
The Kawasaki Z900 RS Doremi features a unique black and green livery with gold finish 18-inch alloy wheels. The quad exhaust system is reminiscent of the Kawasaki race bikes and is finished in matte black. The front features a chrome fender, and the instrument cluster and headlight ring get chrome accents as well. The bulb-type lighting system adds authenticity to the motorcycle.


For suspension, the bike employs inverted front fork and a rear monoshock with remote adjustment. Even the brakes are solid for that vintage charm. Twin radial callipers bite the front twin discs, and a single piston calliper grabs the rear unit. The engine is the same 948cc in-line four-cylinder engine that does duty on the stock bike. It produces 111 PS at 8,500 rpm and 98.5 Nm at 6,500 rpm. The engine mates with a 6-speed transmission.

Bito R&D, an aftermarket parts manufacturer from Japan, has designed this motorcycle. The bike is draped in olive green with yellow stripe livery. The bike features a well-cushioned stepped seat, with a rear luggage rack. The four-to-one exhaust system is an aftermarket unit. This motorcycle also features solid discs for retro appeal.


Coming to the suspension bits, the motorcycle employs upside down front forks and a rear monoshock. The alloy wheels are shod with low-profile Dunlop tyres. The 948cc in-line four-cylinder engine is stock. It is capable of generating 111 PS at 8,500 rpm and 98.5 Nm at 6,500 rpm. The powerplant works in tandem with a 6-speed transmission.
