Words: Jeff Ware Photography: Midori Moriwaki
The Kawasaki Zephyr 1100 was a brilliant bike that really never took off the way it should have here in Australia or NZ. However, if we could have gotten our hands on some of the kit that this Moriwaki Zephyr is decked out in, things would have been a lot different.
If you are mid 40s, loved early 1980s superbike racing and always dreamed of owning your own ballsy air-cooled superbike – this bike will make that dream come true…
I can’t think of a tricker looking, more ballsy and tough looking nakedbike than this 1258cc big bore muscle bike – built by the company that so famously took on the world in the early 1980s with a naked, upright superbike – arguably the world’s first superbike… and one that kickstarted the career of Wayne Gardner.
This bike was built in Japan by Moriwaki Engineering. Starting with a base 2006 Zephyr 1100, the cylinders were sleeved and bored to take huge 80mm Moriwaki pistons, running a compression ratio of 11.5:1.
Stock carburettors (Keihin flatslides will be available soon) are rejetted to suit the hot looking hand bent large diameter Moriwaki Monster exhaust system and modified airbox. Standard camshafts are used…
The sump is replaced with a billet alloy Moriwaki oil pan and braided high-pressure oil lines supply oil to the air/oil-cooled engine.
The engine also has a Moriwaki billet alternator cover, right-hand engine cover, oil cooler and air scoop under the steering head. A trick looking clutch slave cylinder brace mount/countershaft cover is also fitted.
The Zephyr has never been considered a good handling bike in terms of sports riding so Moriwaki Engineering have well and truly fixed that. With decades of racing success including their Moto2 machine, if anyone knows about handling it is these guys…
The forks are gorgeous Ohlins blacked out FS824K/KB 43mm inverted forks in Moriwaki billet triple-clamps, while the rear shocks are Ohlins S36PR1C1L items mounted to a seriously tough looking Moriwaki swingarm.
Marchesini Kompo-Evo forged alloy wheels wear Sunstar rotors and the bike is stopped by Brembo calipers and Plot Swage Kevlar lines. Dunlop Sportmax 120/70 – 17 and 180/50 – 17in tyres are fitted.
To protect the bike, Moriwaki crash knobs are fitted and the stunning paintwork, a replica job of the original Moriwaki superbike, was done by Design Factory, Japan.
Neat frame hole plugs, Moriwaki rearsets, PIAA HID headlight, POSH blinkers and Moriwaki bar risers top off this stunning machine that has more drool factor than any Zephyr we have ever seen, plus it has the power and handling to match the looks…
