I have a 255 RXTX 2008 Riva Stage 2 and the top speed is 113 km. The difference is how fast it reaches that top speed. I don’t want to manipulate the computer because that means changing interior engine components. Like valves.
Changing the speed by computer, so retardish. Engineers made the engine capable of what the actual speed is. You are adding more pressure to engine that it can, and that lowers the lifespan.
