    I have that race on a DVD and love to watch it every now and then.
    Watch at the 4:20 or so mark to see the hinge effect we talk about in action. At least that is what It felt like when I experienced it in a 90 Mph corner.

      Yeah I saw that. A little pucker factor there...

        ur a much braver man than me Ras. I took a corner at 25 mph, and my rear end slid. That was enough for me.

            Yup, to quote Skids, a "real pucker factor."

                  Talk about old school. It's really cool to see these bikes in an all out race. Very impressive to know these things will take all that is asked of them. Great videos, thanks for posting them.

                    That was awesome...Thanks for sharing...Amazing to see those huge 6 cyl CBXs that looked so dominant only to be worn down and surpassed by the 4 cyl mighty XS1100......the rear wheel dis-assy and re-assy was also superior on the Yamaha

                      Everything looks so primitive! I can't believe what they do on those bikes with such skinny tires. I didn't realise an XS1100 could be ridden as hard......

                      I winced at the XS pit stop as he whacks that 'rare' OEM silencer with the axle..not sure if it got a few whacks from the hammer either.....

                      I didn't realise the XS was considered the underdog (except by Avon, of course). Definitely showed its teeth....

                        it was considered the underdog prolly because 1978 was its first year in production and in competition

                            What strikes me is the way the rear end moves as he hits that cornering bump at the beginning of the straight. You can see the rear wobble there.

                            That seems to me to be the trailing arm flexing. I took a look at mine after that and it seems pretty thin considering the side forces acting on the tire in a corner/bump. Has anyone addressed this or tired to strengthen theirs? I've seen swaps.

                            I'll bet trailing arm torsional flex is the main culprit tin the high speed wobble department. Just look at the trailing arm of any modern race bike. Ours seem like bicycle size in comparison.

                            Ultimately though, if the stock XSeleven's handling was so bad it could not have won all those races.

                            Glad you all like the videos.

                              You should have a look at the swinging arm on a CBX1000! It looks like it came off a bicycle........

                              Personally, I don't think the XS swinging arm is up to it. It's obviously adequate but nothing special. Modern ones are all box section, alloy, braced, reinforced etc. The welding on that component is ugly too, I found, especially the two blobs half way down the left side of the arm.
