It takes the popular Savage to the next level, giving monster truck enthusiasts more power, higher speeds, and several extra exciting new option parts as standard equipment!


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 that we were able to gear the truck for higher top speeds, yet still retain excellent punch off the line. A high speed spur gear (49T) and larger clutchbell (15T) are now standard equipment, and we also include an 18 tooth clutchbell high speed on-road driving! Customers will immediately notice that the Savage 25 has more punch and higher top speed.


For added convenience we have added our convenient Roto Start System, eliminating 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 primer button on the fuel tank isn’t needed, so we took it out to help reduce the possibility of air leaks. While we were revising the fuel tank we took the opportunity to move the fuel pick-up 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. The buzz in the pits is that the Savage is the toughest and best handling monster truck on the market, but our R&D team set out to make it even better. To help handle the increased power we’ve gone to a heavy duty three-shoe clutch instead of the standard two-shoe design, which helps launch the truck harder under all conditions. Newly designed ribbed wheel hex hubs are now 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.


The Savage 25 comes completely factory assembled; everything is done for the customer - even the tires are glued to the wheels. In less than 15 minutes customers can be driving their Savage 25 trucks! Based on requests from our RTR customers, we include a complete Instruction Manual that covers the entire assembly/disassembly process. To top it off, we gave the Savage 25 a fresh new coat of paint. The wild red/silver/graphite graphics are sure to attract attention, and the entire body is completely ready to go right out of the box. It’s painted, trimmed and decaled to look exactly like the truck on the front of the Savage 25 box.


Most of the chassis parts are carried over from the Savage 21, proven to be extremely durable and supported by a huge assortment of option parts from HPI and other manufacturers. The running changes to the Savage 25 were designed to maintain the excellent parts support already on the market, yet offer the customer a faster and more durable truck. To wrap up the package, the Savage 25 is competitively priced. Even with the long list of added features – Roto Start, bigger engine, extra gearing – the street price for the truck will be around £75 more than the RTR Savage 21.
