Old Body, New Chassis Conversion – The Complete YouTube Series | Aprilia RS125 Restoration Rebuild Video
There are bike projects… and then there are proper projects. The kind that take years, test patience, and refuse to be rushed. This Aprilia RS 125 build sits firmly in the second category.
This YouTube series documents the full journey of building a two-stroke race replica Aprilia RS125 Restoration Rebuild Video, combining the iconic old-shape styling with a later-model chassis and modern running gear. It’s not a quick flip, not a cosmetic refresh, and definitely not a “content-first” build. It’s a carefully thought-out, nut-and-bolt restoration and conversion done the long way — because that’s the right way.
Why This Build Matters
The RS 125 is one of those bikes that defines an era. Lightweight, razor-sharp, and powered by a proper two-stroke engine, it taught a generation how to ride fast properly. But time moves on, and so does chassis, brake, and suspension technology.
This project set out to answer a simple question:
What if you could keep the classic RS 125 look, but give it the chassis and components it always deserved?
The result is an old-body RS 125 sitting on a later donor bike platform, bringing with it:
Modern geometry
Radial brakes
USD front forks
Digital dash
Improved wheels and running gear
All without losing the soul of the original bike.
A Long-Burn Series — And the Missing Episode
The series began years ago, with each episode documenting another stage of the build. Then… it went quiet.
For a long time, Part Four became the missing episode. Viewers had been waiting since September 2021 to see the finished bike, and many assumed the final chapter was lost forever.
It wasn’t.
The footage was eventually recovered from the period when the bike was sold, allowing the series to be completed exactly as originally intended. That makes Part Four something special — not just the end of the build, but the recovery of a piece of the story that people had been asking for for years.
What You’ll See Across the Series | Aprilia RS125 Restoration Rebuild Video
This isn’t a highlight reel. It’s the full journey.
Across the episodes, you’ll see:
The challenges of mixing old and new RS 125 platforms
The decisions behind component choices
The attention to detail required for a true nut-and-bolt rebuild
The reality of long-term bike projects — delays, rethinks, and persistence
And finally, in Part Four, the finished bike as it was meant to be seen.
Start From the Beginning
While Part Four delivers the payoff, this series works best when watched from the start. Seeing the bike evolve, understanding the decisions, and following the setbacks makes the final episode land exactly how it should.
