RS200 runs on normal fuel and you can use the normally sold unleaded petrol with 91 RON for the riding purpose. The higher octane fuels are mostly used in higher capacity bikes and using them in RS200 would cause no harm and even bring no such performance enhancement. The RS200 performs extremely well for its size and brings out 24.2 BHP and 18.6 NM of torque from its 199.5cc, liquid cooled and fuel injected engine.
