The new THUNDER series is the most valued off-road motorcycle under the APOLLO high-end dirt bike brand RXF, with the theme of »Make Ride More Fun«. With its strong wedge shape, the design adapts perfectly to the rider’s riding and sitting posture, under­scoring the model’s light and high-performance character. At the same time, it embodies the challenge of pushing the envelope.
