The Bulldog: Ninja-Powered BMX Cub!

BMX Ninja Cub 250

Enggal Modified builds a 250cc Ninja-powered BMX Cub! 

In last few years, we’ve seen the rise of “BMX Cubs,” hybrid builds that combine the engine and wheels of a Honda Cub with BMX-style frames, handlebars, and geometry. The result is the dream of every kid who ever stuck a baseball card in the spokes of their BMX to create that card-based BRRRRAAAAP that sounded so much like a motorcycle.

One of the workshops at the head of the trend is Enggal Modified of Banyuwangi City, Indonesia. Enggal himself founded the workshop back in 2004, when he was still in high school, and the shop’s notoriety has spread not only to the top echelons of Indonesian custom culture, but worldwide:

“My workshop does a lot of things, from daily motorbikes to customs to special motorbikes for contests. We’ve managed to bring home many trophies. In 2019 we won the contest held by Suryanation Motorland and went to Mama Tried Show 2020 in Milwaukee.”

Though Enggal Modified works on many different bikes and customs, they have a special love for these hybrid BMX builds:

“We have a favorite product, the BMX Cub, which we have produced since 2018 with a total of 1400 frames.”

Usually, these builds are powered by single-cylinder horizontal engines in the 110cc to 125cc range, like those produced by Honda and Lifan. But Enggal did something special this time around…

Nicknamed “Bulldog,” this BMX Cub is powered by the 250cc liquid-cooled 4-stroke 4-valve DOHC single-cylinder engine from a Kawasaki Ninja 250SL!

In 2016, the Ninja 250L, also known as the Ninja RR Mono, replaced the two-stroke Ninja ZX-150RR that had been in production since 1991. The liquid-cooled 250cc engine, which is also used in the KLX250, makes 28 hp and 17 lb-ft of torque — substantial numbers when mounted in a lightweight BMX-style steel frame! Says Enggal:

“The feel of the ride is just insane — high power with such a lightweight body — it’s so agile.”

As you might imagine, the frame had to be custom-built to fit this larger, 250cc vertical engine and radiator. Many basic BMX Cubs have a rigid chassis, but Enggal knew this BMX Ninja would need suspension to handle the higher speeds. It’s running a set of USD Showa forks from a GSX-R750 up front, and motocross suspension out back — along with disc brakes at both ends and Shinko Big Block rubber.

Now we just have to book a ticket to Indonesia to test-ride this little monster! Below, we talk to Enggal for the full details on the “Bulldog.”
