Details: BMW F800GS frame

BMW_F800GS_frame.JPGWe’re really excited about the new BMW F800GS. Weighing just 174kg dry and making 85bhp through a punchy 800cc parallel-twin, it’s both light enough to actually go off-road (BMW designed it to be as effective as the HP2 Enduro) and fast enough to be good on it. It also packs some seriously clever design solutions, foremost of which is the tubular steel trellis frame.
>BMW_F800GS_seethrough.JPGFirst, the frame is pinched just aft of the headstock, allowing space
for the forks to rotate through an impressive 42° of steering lock
while maintaining the necessary strength and stiffness for good
handling. Conventional designs travel straight ahead, restricting the
degree to which the forks can rotate, and thusly your low-speed,
off-road maneuverability.

protective embrace. In a low- to medium-speed crash, such as you’re
inevitably going to have if you take it to the dirt, you’ll only damage
cosmetic parts, allowing you to keep going. The radiator is also
attached to the frame on flexible mountings, meaning the shock of
crashing shouldn’t damage the water-cooling.  Especially handy if your
BMW dealer is an ocean or two away.

    BMW finally hit it right with this one. A good balance between power/light weight and touring capacity. I’ve seen it first hand, if you jump a 1100/1200 GS more than 2-3 feet in the air its going to snap the paralever. This one looks more sturdy and able to handle some more serious off roading. Plus you wont’ have jugs hanging off the sides waiting to catch a rock. I just hope it can do well fully loaded, even 2-up on the highway. And that it puts out enough amperage for all the accessories unlike the 1200.

    Jumping a 1200GS more than 2-3 feet in the air, that’s insane, what mortal human would even care about that? Your point is very valid though, the 1200 is just way too big.

    I’ve never really been too excited about BMWs, but i want this one bad. I ride a TE610 or a knobby-clad V-Strom 650 right now, depending on where i want to go. The V-Strom is impressive for what it is, but still leaves a lot to be desired off-road. The 800GS looks like a comparable size package, with more power and FAR better suspension. SIGN ME UP! (just hope i can figure out a way to pay for one)

    At first I liked this tough looking 800, but the more I look at the frame the less I am convinced hmmmm I mean come on this is a hefty priced BMW and one expects the best, but in the end what do you get, a trellis frame with the engine as a stressed member in an off roading/adventure bike…..in my opinion this setup is not sturdy enough for the bike it wants to be. Suzuki, Ducati and other makes have used this type of frame for road bikes which is ok, but for what this bike is intended I think its a big NO NO. I already read about some complaints on how the upper bolt holding the rear shock to the frame bent causing more structural damage to the rest of the frame. The engine is a parallel twin which in itself is a good choice but it better be nice and balanced (balance shafts) for the tight twisty stuff. I think a full tubular frame is always the way to go for off road/adventure and also the way the rear shock is connected with a long thin bolt must be re-engineered….. from BMW and the prices they ask I would expect a super mega sturdy frame and engine that even if hit by a train would remain intact if they want to keep their name on top…..

    The rear frame isnt so strong! Mine fell with zero speed and bented due to forces transfered from the rear peg to it. zero speed i said, like dropping the bike from the side stand and it went in and twisted also! I find this unacceptable and also 900euros for such a rear frame also unacceptable.
