Worthy of the ‘RR' insignia, this racing Truggy is loaded with a SIRIO engine for even more speed!
From the most respected racing engine brand in the world, the ‘SIRIO S21 BK Evo.4' brings its dynamic performance to the rough and tumble of Truggy racing. Built tough from the DNA of the World Champion, the INFERNO ST-RR combines with the SIRIO S21 BK Evo.4 engine in the ultimate off-road dream machine. Stadium truck strength unites with racing buggy performance and a power source to create a Truggy to rule all others. Starting with a longer wheelbase than the preceding ST-R, various improvements and upgrades such as the inclusion of big bore shocks and the SIRIO engine turbo boost racing performance. The user-friendly engine's torque can be felt through the entire power range, especially with the sharp pick up from standing starts. The engine also produces its speed and power reliably and consistently over long periods on all surfaces from race circuits to dirt tracks. With the SIRIO engine fanning the flames of the INFERNO ST-RR, you can experience the most dynamic Truggy performance imaginable.
