How we stumbled upon this gem of a build

We jumped on board as a sponsor for the Thriller Motorsports AFTN team for 2025, so when Franko heard he'd be building a couple of bikes for his best mate Jack he gave us a call to see if we wanted to head up North to document the builds, this is part one where we tear down and build up Jack's 125... guess you better stay tuned for part 2. We haven't done a 125 bike build since Wreckers to Checkers Season 2, so when that phone call came in it was a no brainer, we jumped on a plane up to Townsville to join Franko in building Jack his summer vacation motocross two stroke. MotoGP legend Jack Miller has a bit of an affinity with 125 two-strokes, and we don't blame him. Jack picked up a brand new Yamaha YZ125, and since no one knows how to build Jack Miller a new dirt bike better than Franko, he jumped on the tools taking this from a stock YZ to a Pramac Purple race bike-inspired machine.
