[QUOTE="69ST, post: 164231, member: 5"] I'm interested in your impression of the difference the G`Craft swingarm makes. IDK, maybe the K0 swingarm is more flexible than the K1-later; Honda wouldn't have gone to fully-boxed construction for shits-n-giggles. I've run across a few tweaked K0 arms (never a later version) and they are shockingly flexible, as a loose part. That said, once the wheel assembly is torqued into place, it's a whole different thing. Axle, swingarm pivot and motor mount bolts are structural components, thus torque is important. Personally, I've never felt any difference from a swingarm change. IMHO, the swingarm isn't being stressed very much by riding. The main deflection point is at the pivot and virtually all of the undesirable lateral motions comes from the combination of the swingarm bushings and frame...that is its weakest point. Biggest improvements I've noticed, in descending order: road tires, real shocks, swingarm pivot bearings (needle instead of rubber), frame bracing, swingarm itself. Squeeze the chain, top & bottom, and you'll see how the wheel is moved, toward the LH side of the bike...as well as where the motion is centered. FYI, one hand can generate far more force than the machine will ever "see" while riding. IMO, it's an extreme test but good for a visual demo, as well as finding anything that is seriously loose.
