The truggy racing revelation!
Striving to create the best competition truggy engine, O.S. engineers made a crucial trackside observation that influenced how they designed the 25XZ. While you can push ROAR's legal limit with a .28, power alone doesn't get you the win.
You also need the fuel economy to stay on track while other drivers tick off precious time in the pits. You need a low center of gravity that helps you hold your lead without letting up in the curves. And you need the ability accelerate smoothly at any point in your engine's rpm range.
Like larger engines, the 25XZ delivers all the speed any racer can use — but reduces weight just enough to give you every other advantage, too. It's a racing revelation, available now at your favorite O.S. dealer.
- Premium power for owning the winner's circle at 1/8 scale off-road events!
- More muscle than a .21 — more compact than a .28.
- Lower center of gravity aids in handling.
- The slide valve 21JN carburetor allows quick and easy tuning to specific race conditions and has four separate adjustments: High Speed, Mid-Speed, Low-Speed and Throttle-Stop.
- 10-fin blue anodized cooling head reduces heat.
- Five ports
