The Two-Stroke World Championships went down at Glen Helen Raceway a few weeks ago and our buddy Trevor Stewart finished in the money in the Pro class aboard our 2025 Yamaha YZ250 test bike. Of course, he didn’t race it stock…we sent it to the crew at Bill’s Pipes and they beefed it up with an Athena 300cc kit, a Moto Tassinari reed block, a Hinson billet clutch, and a custom-made Bill’s Pipe and silencer to complement the extra cubic centimeters. To handle the extra power and speeds that it would generate, enzo racing fine-tuned the suspension for Stewart. Finishing touches included Pro Taper bars, an Acerbis plastic kit, a Guts Racing seat cover, Backyard Design graphics, and a set of super-sharp titanium footpegs from Moto Stuff.
