GSX-R1100 Power: Suzuki Inazuma 7/11 Café Racer

GSX-R1100-Powered Inazuma 750 from Moto Adonis… 

The Suzuki GSX750 Inazuma (Japanese for “Lighting” or “Thunderbolt”) was a retro-inspired UJM with a steel cradle frame, twin shocks, conventional forks, and a detuned 86-bhp version of the 1980s GSX-R750 air/oil-cooled engine. The bike was designed to rival such machines as the Kawasaki ZR-7 Zephyr and DOHC Honda CB Seven Fifty. It performed competently, if not blowing many minds in stock trim.

However, the Inazuma found a second life in the hands of customizers like Job Leussink of Holland’s Moto Adonis, who’s owned nine of these bikes to date! In fact, he’s currently building one of them into a turbo project…

The bike you see here was Job’s second Inazuma build, and in his estimation, the most beautifully detailed of all. He actually built the bike for himself, but ended up selling it to raise funds for an epic ride to Mongolia on two wheels.

The biggest modification? The installation of a GSX-R1100 engine! In Gixxer circles, the adding of an 1100 engine to an air/oil-cooled GSX-R750 results in a so-called “7/11.” Examples include Digs Rush’s Pick ‘N’ Gixx and Icon 1000’s “Gixxer Johnny” builds. In the case of this Inazuma 750, the 1100 engine boosted output from 86 to 130 bhp — a 51% increase!

Job was wise enough to upgrade the suspension and brakes in parallel with the engine. The bike has been outfitted with Hayabusa forks and brakes, ensuring this high-powered Inazuma can handle and stop as well as it accelerates. 

On the aesthetic side, there’s a sleek and classic café racer tail section fitted with a handcrafted seat. Job retained the original tank — one of his favorite elements of the stock Inazuma — but the bike is wearing a lovely custom paint scheme from head to tail.

One of Job’s proudest achievements here is the custom stainless steel exhaust, which he built himself — one of his first stainless exhaust systems. It’s capped with a pair of SC Project mufflers that sound the business.

In Job’s opinion — and we’d agree — this is one of those builds where all the proportions, colors, and modifications come together just right:

“Everything just lines up perfectly — it has the right stance, the right proportions, and, in my eyes, it embodies exactly what a true café racer should look like. Riding it feels just as good as it looks: powerful, responsive, and full of character.”

If you had any doubt as to how much this Inazuma build means to Job, check the tattoo he got of the bike!

Hats off to Job for this gorgeous Inazuma 1100 build. And we can’t what to see that turbo Inazuma when it emerges from cover…

Inazuma 1100 Café Racer: Builder Interview

• Please tell us a bit about yourself, your history with motorcycles, and your workshop.

My name is Job Leussink, and I am the owner of Moto Adonis. I got my first moped when I was 11 years old, and it needed some repairs right away. That’s when my passion for working on bikes started. Now, at 33 years old I have 22 years of experience working on mopeds, cars, and of course motorcycles. Over the years, I’ve been able to turn my skills and creativity into a business where I build awesome custom motorcycles for customers.

• What’s the make, model, and year of the donor bike?

Suzuki 750 Inazuma 2002.

• Why was this bike built?

I built it to sell it and with the money fund my travel to Mongolia on a bike.

• What was the design concept and what influenced the build?

I’ve always been a huge fan of the Inazuma, mainly because of its unique tank design and the classic look the twin rear shocks give it. This was actually my second Inazuma build, and by now, I’ve owned nine of them! I still own two, and one is currently being built into a turbo project.

Out of all my builds, this one still stands out as one of the most beautifully detailed. Everything just lines up perfectly — it has the right stance, the right proportions, and, in my eyes, it embodies exactly what a true café racer should look like. Riding it feels just as good as it looks: powerful, responsive, and full of character.

• What custom work was done to the bike?

First, I fitted a GSX-R1100 engine into the frame, adding a serious boost in horsepower. To handle that extra power, I installed a front fork and high-performance brakes from a Hayabusa, ensuring the bike can come to a stop just as well as it accelerates.

Of course, I added a sleek café racer tail section, complete with a handcrafted seat. The bike also features an awesome custom paint job that really makes it stand out. One of the highlights is the custom stainless steel exhaust system, which I built myself — one of my very first stainless steel exhaust projects!

• Any idea of horsepower, weight, and/or performance numbers?

The bike weight is original 207 kg, but I made it lighter, so 197kg I think. And it originally had 86 hp, but with the GSX-R engine, now it’s 130hp.

• Can you tell us what it’s like to ride this bike?

It’s a beast to ride. I once hit 250 km/h (155 mph) on the German highway. That was very fast without a windshield.

• Was there anything done during this build that you are particularly proud of?

My first stainless steel exhaust.

• Is there anyone you’d like to thank?

Arthur Renkema For letting me use his garage at the time.
