2008 Bmw G 650 Xmoto
An evolutionary version of the Rotax 654 lump from the '94 F650, infused with smoothness and enthusiasm with a lighter crankshaft, more efficient bottom-end bearings and a lighter 280-watt alternator. A more efficient cylinder-head design adds 3 horses to the peak.
What looks like your basic aluminum-spar skeleton is made up of four sections. Welded steel spars comprise the heart of the structure, bolted to aluminum castings that merge at the swingarm pivot. The front downtube and rear subframe are aluminum as well.
A single Brembo caliper and 320mm front disc slow the lightest of BMW's three X-spec singles nicely, with or without the 240mm rear disc. Our bike arrived sans optional two-channel Bosch ABS, which adds 3.3 lbs and $670 to the poundage and price, respectively.
The brake and gearshift levers are aluminum forgings. So is the sidestand, which unbolts easily. The tapered-aluminum handlebar rides in rubber mounts to cut vibration, and the battery lives just behind the bar clamp. LED taillight is tiny, yet brilliant.
You can do a lot with 47 horses spread over a curve like this. Trounce Kawasaki's KLR650, for instance. But one big piston loses out to a gang of smaller ones as revs build, even when it's pushing a 363-lb. package.
Tall and remarkably svelte, Xmoto accommodations are Spartan, but comfortably neutral. The firm, equally svelte saddle is motorcyling's answer to a Victoria's Secret thong: you need long legs and the right kind of physique to make it work.
