A Two-Stroke Street Tracker from House of Customland…
Did you know that Kawasaki, for years, produced a small, two-stroke version of the Ninja for the Asian market? It’s true. In 1996, they launched the Ninja ZX-150RR, a 149cc two-stroke that would remain in production for more than 20 years.
In 2014, Indonesia received a redesigned version, whose liquid-cooled 149cc engine boasted KIPS (Kawasaki Integrated Powervalve System) and HSAS (High Performance Secondary Air System), making 28 bhp while still meeting Euro II emissions regulations. There was also a naked Ninja SS 150 version.
Recently, we heard from our friends at Indonesia’s House of Customland, a kustom kulture mini-museum and workshop whose Suzuki TS100 scrambler we featured earlier this year. Now the crew from Surabaya is back with “Green Poison” — a Ninja 150 two-stroke street tracker.
Last year, they bought the bike in bad condition from a friend, and set about restoring it to rideable condition. But once that was achieved, the custom itch had taken hold:
“Although it could be ridden again as a means of daily transportation, I still wanted to explore more in terms of upgrading the engine, so that it would be more aggressive. It didn’t end here; my creative side reappeared, wanting a change in shape from the beginning.”
Working with Ibnu Maliki (@motorcycle.trade) and painter Fahmi Danny (@denokpaint), they transformed the small, two-stroke sport bike into a flat tracker, fabricating a custom gas tank and tail section, outfitting the bike with 18-inch TK Racing wheels, giving the engine an UMA Racing big-bore kit and BPRO radiator, and much more.
“Green Poison” seemed a particularly fitting name:
“The mention of ‘Green’ in the name comes from the unique color of Kawasaki motorbikes, and ‘Poison’ is inspired by the rampant poisons of two-stroke motorcycles, which have not subsided for fans over the years…”
Ninja 150 Tracker: In the Builder’s Words…
The donor for this build is a 1998 Kawasaki Ninja S, 150cc two-stroke. With the increasing trend of 2-stroke motorcycles, we decided to build this bike with the concept of a flat tracker. We made a custom gas tank and tail section without cutting the original frame (to maintain the originality of the motorbike).
On the engine side, we upgraded to a bore-up kit from UMA Racing, coupled with a radiator from the BPRO brand and a custom full-system aluminum exhaust, making this bike ready to race.
Aluminum alloy wheels from TK Racing, size 18 inches, wrapped with multi-purpose tires from Shinko. Our braking system uses disc brakes at the front and rear.
The construction of this motorbike was assisted by Ibnu Maliki (@motorcycle.trade) and finished by Fahmi Danny (@denokpaint) with Kawasaki’s green color, and stripping and manual lettering to add to the impression of a fierce racing motorbike.

• Why was this bike made?
Initially, I bought this 2-stroke Kawasaki Ninja motorbike in 2021 from a friend in bad condition, so I had to restore about 50% of it.
Although it could be ridden again as a means of daily transportation, I still wanted to continue to explore more on the upgrade side of the engine, so that it goes more aggressively.
It doesn’t end here; my creative side reappeared, wanting a change in shape from the beginning. The motorbike was born as a road racing style sport bike, but I transformed it into more of a dual purpose purpose machine, with Flat Track style.
• Can you tell us what it’s like to ride the finished bike?
This motorbike is no longer a pure asphalt road racing machine, as its functionality has been shifted towards the dirt — or more specifically, flat track racing. That said, the bike is still comfortable to ride on two ends of the spectrum — both on the asphalt and the dirt.
• Was there anything that was done during this construction that you were very proud of?
I am proud to give this bike the name “Green Poison.” The mention of “Green” from the name is taken from the unique color of Kawasaki motorbikes, and “Poison” itself is inspired by the rampant poisons of two-stroke motorcycles, which have not subsided for fans over the years — on the contrary, they’re increasingly becoming “prima donna” in the craze of two-wheels.
What’s more, with Cyberpunk nuances, the bike seems to be saying that the original frameworks of things are not so young any more. It carries the spirit of new technology, which is more aggressive in fighting backwardness, and has high hopes in an increasingly cyber future.
• What’s next for House of Customland?
We have a small 135cc Yamaha RX King engine that we plan to build into a chopper.
