Once again, you have listed a set of attributes that belong to the suspension components, not the frame. Weight transfer entering corners is handled by the suspension. The forks may dive as much as 7-8" (from the top) during this maneuver. How much do you think the frame moves? nope, your right. Frame is 100% ridged, no flex at all. read this... http://www.bikeforums.net/archive/index.php/t-24598.html and this. http://www.sheldonbrown.com/frame-materials.html so you can understand the principles of frame design. and if you think shock absorb 100% of everything then you have never even ridden a dirt bike... i know after a race i feel like i have been through a dryer.... so i know the frame is transfering energy... further evidence that the suspension doesn't take all the energy... http://www.obergsports.com/p_rubberMount.html rubber mounts on tripple clamps. Car frames even have flex, much more actaully due to their design. http://auto.howstuffworks.com/question432.htm but there are sway bars. frames have flex in them. now i ask you to prove me wrong. From TW MOTO: Q: So it was all a matter of Rigidity? A: Yes, We just couldn't get the fram to flex enough for my liking. WE could have, but it wouldn't have been AMA legal... ...At times it was very frustrating to me, and i just wanted to take a grinder to my head tube to remove some material... ...Yamaha told me i would be very happy with the 08 Bike, because that's what the major model change was... Even more evidence that bikes have frame flex. CLASSY CHASSIS The biggest change KTM made for '05 is the frame tubes. Last year both the 125 and 250SX were so fast that the chassis couldn't keep up with the motors, making the bikes very scary to ride in certain situations. Much of this problem was the flex of the frame, so this year KTM ditched the old school round tubing they've been using since the beginning of time and replaced it with an oval chromoly-steel tubing. The new-generation frame has also been reinforced with countless gussets and welds, making it much tougher and less prone to flexing. The lateral, tubular design is meant to help front and rear end stability, a big problem on the KTMs of the past. Because the shock is mounted on the side of the frame and not directly in the center of the chassis, the KTM previously had a tendency to swap sideways in the whoops or in very rough situations due to frame flex. (If you ever watched Langston in the whoops at an SX you know what we mean.) This new frame design was developed to combat that problem head-on.
