The engine construction broadly remains the same, but the RS200 gets a new head and, more importantly, fuel injection as against carbureted fuel supply in the 200NS. Power rating has gone up by one horsepower, and the RS200 flaunts 24bhp that peaks out at 9, 750rmp. The throttle response is definitely crisper and instant on this bike, and thats sort of needed as well-to offset the bulk of about 15-20 kilograms thats gained in front of the fully faired plastic body work and other technical components like the ABS unit, etc.
