Lucky Me: Dyna Street Tracker by Robot Motorwork

Dyna Street Tracker

“Lucky Me” — A Big Twin Street Tracker from Robot Motorwork…

The Harley-Davidson Dyna platform debuted in 1991, featuring an all-new chassis, traditional coil-over rear suspension, Big Twin engine, and more. Traditionally, the Dyna lineup included models such as the Super Glide (FXD), Street Bob (FXDB), Low Rider (FXDL), Wide Glide (FXDWG), Fat Bob (FXDF), and more. For 2012, the Dyna engine was upgraded to 103 cubic inches (1,690 cc), making some 64 horsepower and 81 ft-pounds of torque at the rear wheel.

Enter Muhammad Robbi, the founder of Indonesia’s Robot Motorwork — based in Yogyakarta City. Robbi and crew set out to build a Dyna street tracker that would be comfortable on the road, but capable of light off-roading.  The donor was a 2014 model:

“We got this bike in a really bad condition — oil leaks, unbalanced engine sound, and compression leaks.”

A complete engine rebuild was required — the crew’s first time rebuilding a Harley-Davidson Big Twin. But once they buttoned the big 103-inch engine back together, it worked great, leading to the bike’s nickname: “Lucky Me.”

As you can see from the photos, the engine was just the beginning. The bike is covered in custom-made parts, including a one-off swingarm, 2-inch stainless exhaust, headlight built from 1.6mm steel plate, and much more. Below, we get the full story on this Big Twin street tracker.

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

The concept is street tracker, influenced by flat track racing videos from youtube. It’s not built for racing, but for daily activity. Looks simple, powerful, easy riding with comfortable body position. Sometimes the owner also likes to ride this bike off the road, that is why we chose dual purpose tires.

• What custom work was done to the bike?

Still using the original main frame, just customized the rear sector. Gas tank, rear cover, seat, headlamp is custom-made using 1.6mm steel plate. The swingarm is also a custom made. Custom exhaust using 2-inch stainless steel pipe. Got the wheels from a junkyard, both of them actually are front wheels. We modified and customized it into a rear wheel. We made a custom rear sprocket and disc brake brackets.

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

All things in this bike made me proud. But the most came from the engine restoration process. We got this bike in a really bad condition — oil leaks, unbalanced engine sound, and compression leaks.

First time for us to fully rebuild this kind of engine — the result was so great. One time work with great result. Everything runs well up to now. That is why we named the bike Lucky Me.

  1. That is one of the nicest Harley’s I’ve ever seen. Innovative and way creative use of the Big Twin. Love the exhaust.

  2. How does a 2014 have an Evo engine on it?

  3. How can a 2014 have an Evo engine on it?

  4. I love that exhaust. Beautiful welds and the exit under the tail is incredibly-well executed. I’m not the biggest fan of Harley builds but this thing is pretty special

  5. I generally don’t appreciate anything past the 1999 evo engine but this work of art really grabbed me! You really have a builder’s vision and the heart of an artist! I love old Pan and shovel builds but this bike is immaculate. You have a real eye for function and that gives it beauty.
