// for most all rider abilities . Also highlighting the sleek shape are the new radiator shrouds introduced on the RR a few months ago , and a number of different components , such as the all-new designed handguards .
Enhancing the overall performance of the 4 stroke models , Traction control is featured with every 4 Stroke Race Edition model . The Traction Control function can be engaged at any time from the button on the control panel just above the gas filler . As both the TC function and engine map selection function are controlled from this panel , it has two control buttons and two separate indicator LEDs for the two functions . This system alters the ignition to slow down the rear wheel speed in slippery situations .
To save weight , all 2 Stroke Race Edition and 300 RX models are set up to run premix however oil injection can be added as an accessory item to the Race Editions .
Compared to the RR models , the cylinder of the 300 cc engine now features a modified exhaust and transfer port geometry and a different cylinder head , combined with a differently calibrated power valve . The cylinder head , different from standard both in terms of modified flow geometry and combustion chamber geometry , ensures a higher compression ratio , resulting in a substantial increase in performance . To better manage the increased power output of the engine , the power valve has also been modified , changing the internal spring and adjustment system to ensure fullbodied and readily accessible power delivery throughout the rev range . Different ignition timing completes the package .
The RX engine is unique to this model only , with a 72mm x 72mm bore and stroke , smaller crankshaft , combined with a larger 38mm Keihin carburetor for maximum performance required in Moto conditions .
The 200 cc engine also retains a different cylinder head to the standard version , as well as a single , stiffer power valve , instead of the two used in the RR . All this contributes to increasing power at mid to high engine speeds .
