When did the BMW G450X dirt bike come out?
BMW’s G450X has been very mysterious. It was first announced in late 2007, apparently aimed at taking the dirt world by storm. At that point, the mission was clear. It was a hardcore dirt bike aimed right at KTM, as the two companies prepared to fight to be Europe’s largest motorcycle producer.
How manybhp does a BMW G450X have?
All you do is complete a circuit with a £5 plug and the BMW goes instantly from 41bhp to 52bhp. It may only be a 450cc four-stroke single, but the BMW is boasting heaps of cleverness like that. At the heart of its innovation is the genius drive-sprocket arrangement. The entire motorcycle has been built around the gearbox sprocket, and here’s why.
Is the competition pipe on a BMW G450X?
The competition pipe is still reasonably quiet and has a spark arrestor, but it does away with the catalytic converter in the DOT pipe. BMW says this extra pipe adds $250 to the price of the bike, so if you don’t want it, ask for a discount.
Where is the gas tank on a BMW G450X?
It has a closed-loop fuel-injection system, a countershaft sprocket that is mounted on the swingarm pivot, a clutch that is mounted on the crankshaft, a gas tank located under the seat, and dozens of other elements that are just different. Each one of those elements has been attempted elsewhere.
Can a BMW G450X be a dirt bike?
BMW offers only a street-legal version of the G450X, but hands you all the parts to make it a dirt bike. That includes gearing, a jumper to convert the EFI system to a competition map and a whole new muffler.
Where does the BMW G450X engine come from?
The engine, by the way, is manufactured by BMW’s partner in Taiwan, as are some of BMW’s other motors. The swingarm is extra long because of the countershaft design, which means that BMW engineers had to invent their own suspension design—it wasn’t like they could copy the layout of some other company that was doing the same thing.
What kind of fork does a BMW G450X use?
One of the big challenges is trying to deal with the effect of engine torque on the suspension, which is exaggerated by this setup. BMW does it with a no-linkage Ohlins shock mounted at a fairly laid-down angle. Up front, BMW uses a 45mm Marzocchi fork.
