BMW G 450X (2011)

The BMW G 450X is a finely tuned, uncompromising sports enduro that embodies the company’s 80-year offroad tradition. Its 449cc single-cylinder engine, boasting 50 horsepower and 4 valves, now features a revised ECU mapping that reduces fuel consumption and engine braking.

Thanks to a new exhaust system and other performance enhancements, the G 450X tips the scales at just 110 kg curb weight, making it a formidable force on the track. Its suspension has also been recalibrated, with a Marzocchi fork and Hlins shock absorber working in harmony to deliver exceptional handling and stability.

With its updated features and refined design, the 2010 G 450X is an even more formidable competitor on the world stage, ready to take on the most demanding contests with confidence and poise.
