The heart of the Savage 25 is the powerful new Nitro Star S-25 that has 20% more displacement than the previous model. It's a .25 cubic inch (4.1cc) big block engine that features a billet aluminum heatsink head for extra cooling, dual bushing aluminum connecting rod, true ABC chrome sleeve construction for durability, and a simplified dual needle 7mm slide carburetor for easier tuning with a composite body for better performance at higher temperatures. The new S-25 is so powerful it been geared for higher top speeds, yet still retains excellent punch off the line. A high speed spur gear (49T) and larger clutchbell (15T) are now standard equipment, and also includes an 18 tooth clutchbell for high speed on-road driving! You'll notice immediately that the Savage 25 has more punch and higher top speed.

The convenient Roto Start System, eliminates the pullstarter from the engine! Owners will no longer have to worry about getting blisters from trying to start their engines - a press of the button and the engine roars to life! An added bonus of the Roto Start is that the primer button on the fuel tank isn't needed, so it was taken out to help reduce the possibility of air leaks. The fuel pick-up has been moved to the rear of the tank to help make the truck run more consistently through the entire tank of fuel. A ceramic in-tank fuel filter is now standard.

To help handle the increased power a heavy duty three-shoe clutch has been installed, which helps launch the truck harder under all conditions. Newly designed ribbed wheel hex hubs are included to help cope with the increased power, gripping the wheel better to prevent stripped wheels. Stiffer shock springs are now standard, giving a flatter trajectory over large jumps and crisper performance when cornering at higher speeds.
