User manual BMW G 450 X BROCHURE

[. . . ] COMES FROM REVOLUTIONARY FRAME/SWING-ARM DESIGN. Being unstoppable means doing things better than the rest. The design of the swing-arm is nothing short of revolutionary: for the rst time ever on a production motorcycle, its pivot point shares an axle line with the drive sprocket. As a result, the compression and rebound of the suspension do not alter the length of the chain, and so do not impair the ef ciency of the drive train. [. . . ] Digital engine management and two sequential throttle valves also further improve performance, and ensure that the engine reacts precisely to throttle inputs. Unlike on most motorcycles, the clutch is now mounted directly on the crankshaft and can thus be more compact, as its increased revolutions reduce the amount of torque it needs to transfer. Furthermore, the engine is angled forwards, optimizing weight distribution and allowing straighter ­ and therefore more ef cient ­ intake pipes. The air lter is made of a smooth foam eece and can be changed quickly and effortlessly. Finally, the standard silencer with catalytic converter can easily be swapped for an Akrapovi ® titanium slip-on system for competition riding (optional, not homologated for on-road use). TECHNICAL DETAILS: CHASSIS The rear wheel of the BMW G 450 X measures 18 inches in diameter and is held in place by a robust aluminium double swing-arm. An Öhlins suspension strut is attached to this via bolted aluminium brackets, offering 320 millimetres of travel, and fully adjustable compression and rebound damping. The spring preload can also be adjusted, via ring UNSTOPPABLE TRACTION. COMES FROM A SUPERB CHASSIS. To be truly unstoppable, you need outstanding grip, which means maximum ground contact at all speeds and on all surfaces. The front of the G 450 X features a fully adjustable Marzocchi upside-down fork with 300 millimetres of travel, which effortlessly handles even the bumpiest terrain. At the rear is a fully adjustable Öhlins monoshock suspension system, also fully adjustable and with 320 millimetres of travel. All this sophisticated engineering has been introduced with one aim and one aim only ­ making you and your machine unstoppable. nuts. The 21-inch front wheel features an upside-down Marzocchi fork and 45-millimetre stanchion tubes. This too is fully adjustable for both compression and rebound damping, and travel here is 300 millimetres. Stopping power is provided by a Brembo brake system, with a doublepiston oating caliper at the front, and a single-piston oating caliper at the rear. The diameter of the front brake disc is 260 millimetres, while that at the rear measures 220 millimetres. To protect the G 450 X in the most challenging off-road conditions, the motorcycle also features a shatterproof lightweight plastic bash plate, which has already proven its worth in competition riding. TECHNICAL DETAILS: RIDING POSITION UNSTOPPABLE TRACTION. [. . . ] They are screwed onto the aluminium hand guards. the chain guard extends its service life still further. It resembles a rubber tube in form and covers the chain in its entirety, protecting it against dirt and reducing wear and tear. SLIP-ON RACING SILENCER (NOT HOMOLOGATED FOR ON-ROAD USE) Featuring the same design as the standard silencer, the racing edition is considerably lighter than the standard component (by LOW SEAT, BLACK Reducing the seat height by 20 millimetres offers shorter riders better control of their machine when riding off-road. one kilogram), due to the absence of the catalytic converter. It can easily be tted in place of the standard silencer, and no further modi cations are required. [. . . ]
