The Crossfire CF50 was engineered from the ground up with weight, height and handling in mind. For our smallest riders we have used the lightest materials. These include aluminium wheels and hubs, aluminium engine case and cylinder head and forged triple clamps and risers. https://www.gmxmotorbikes.com.au/50cc-dirt-bikes/crossfire-cf50-50cc-kids-dirt-bike-blue
