2011 BMW G450X
When the 2009 version of the 2011 BMW G450X premiered, the thud you heard was the jaws of countless Beemer enthusiasts the world around. After all, this was the very first time that the Black Forest Bavarians had ever ventured into the world of relatively low displacement enduro bikes, and to produce a debut model that was so successful both in the showroom and on the race course was nothing short of a seismic event.
The BMW factory has not stopped with the 2009 model but has continued to implement various improvements in the G450X's 2011 model year. The new exhaust system is surprisingly not approved for on road use (so it will be very difficult to get this bike registered with a license plate in most states), but it does include an innovative reflecting and absorbing function to fit snugly within the noise limitations decreed by the FIM. The G450X saddle has been reshaped to be taller in the center section and is fitted with a different consistency of foam to make it more suitable for hard enduro use.
The G450X's 449cc single cylinder, four stroke, four titanium valve, twin overhead camshaft, water cooled masterful thumper benefits from fuel injection and a fully electronic ignition to generate truly awesome power output in both the horsepower and torque curves. The 1.66:1 craaaaaaaaaaaaaaaazy oversquare bore and stroke of 98mm x 59mm works with a 12.0:1 compression ratio (possibly to ensure that there is sufficient burn in that skillet-shaped a combustion chamber) to maximize hp at the higher rev range, and the result is that the G450X's throttle has access to tractable power virtually from a few hundred revs above idle all the way to barely touching the redline.
The suspension on the G450X has been revised from 2009 to be dialed in even better to grueling enduro conditions. The 45mm USD fork has 11.8 inches of wheel travel while the direct mounted Ohlins shock out back provides an extremely generous 12.6 inches.
All of these goodies are packed into an extremely attractive package which even when fully loaded with fluids still weighs just a few pounds more than Kawasaki's KX450F motocrosser which equates to outrageous agility out on the trail.
The 2011 BMW G450X is a real eye opener as you wouldn't expect the company that became famous for its boxer horizontally opposed air cooled twins with the big chrome toaster insets on the tank to produce a class-topping enduro motorcycle of this type. But they did, and it's a totally amazing racer.
