This is the RB Concept Circuit 11 .21 9-Port Competition 1/8 On-Road Engine. This engine was developed with all the tricks, tweaks, and RB know-how for the most demanding RC class, 1/8 on road. This engine is the pinnacle of RB performance!

The C11 is now offered with a black crankcase that has been strengthened to help prevent distortion and vibration, while increasing heat dissipation in order to provide a more reliable and powerful engine. The crankcase has also been modified for improved internal flow, providing increased power and efficiency. The enhanced 9-Port sleeve design features the exclusive RB "Multi Exhaust System" (MES), providing linear power while ensuring improved reliability and increased lifespan, while the O-Ring supported turbo combustion chamber helps to prevent vibration and dirt contamination. The 14.5mm long stroke crankshaft has been double balanced with tungsten slugs and has been silicone ramped for lightweight vibration free performance. This crankshaft rotates in a 14.5mm ceramic rear bearing and "Z Special" front engine bearing, further reducing vibration and increasing engine performance. When combined with the CNC Machined Lightweight Domed Piston the C10 produces incredible RPM's, and the "smart groove" allows easy removal of the wrist pin clips. This engine offers all of these features and more, adding up to an engine that truly has been designed for racing at the highest level!
