Rally bikes are of many variants.. if we are talking about endurance races like the raide the himalayas.. the bikes need to be made specific to withstand the roads at that levels and be able to perform on those kind of terrains. If we are talking about motocross races, the bikes are made to perform depending on the track the race is planned on. so the bike will range from bottom end performances to mid ranges depending onthe kind of turns in the tracks. Generally moto bikes lasts for a single of mostly 2 races, so the kind of engine building is drastic to make power. However i dont think you would need that kind of machine which you have to build after completing few thousand kms. To get power from the machine is hell lot tricky given the importance to its reliability.
Since i also own an RX and in the process of making it fast. This is what i have done on my bike to give you an insight.
Custom porting (Stage II)
Custom Chambers
RXG Stock Carbs - You can choose a flat side carb for more power delivery with proper upjetting.
Stock Rims 18" - You can choose alumunium rims for making the bike lighter
Reed Valves - you can upgrade from choosing between Fibre to carbon fibre reeds
Head Shaving - to increase the compression.
Custom CDI.
Filters - UNI's

Doing this would give you enough power to enjoy the ride while keeping the mind and eyes open because if any one of them is not working one would end up crashing somewhere for sure. And yes there are more things which can be added to make it more faster.
