    rpm redline

    Im new to these hi revving bikes. It seems when I try to wind it out beyond 4000-5000 you really have to make it scream. I think the most rpm ive had it up to is 6000, with the exception of today when I got it up to 110mph indicated. I forgot to look at the rpm because I was fixated on the road and speedometer while scenarios of my front tire flying off played in my head.
    My clutch isnt slipping. I m also a little bit afraid of breaking something.
    Anyone tell me what they experience when hi revving on a similar model?

    You're just coming in to the power at 6k. Give it some welly and run it past the redline every now and then. You won't hurt it and you may find out what power your bike really has.

      One day I was riding my 1100 and accidently hit 10,500 rpm in 3rd gear. I was winding it out much the same as I do my 850, but I noticed when I did that, I was doing about 75mph in a 55 zone. I quickly went to higher gears and slowed down about 60 at the same time. Power band is around 5800 rpm and doesn't top until it's around the red line. By the way, nothing was damaged. Rev it and enjoy!

        High revving? These things are relative slugs when it comes to rpm compared to some of the modern stuff. I read an article recently, I thought had to be a typo, saying the new R6 spins 18.5K at redline. Of course it probably doesn't make any power until 10 or so.

        At 6K your big ol 1100 is just coming on. The torque and the HP seem to spike right about there and she'll take off like you just lit a retro rocket under it. In the twisties I generally kept it spinning between 5.5 and 8.5 grand so you could really blast out of the apex. Plus that big heavy crank will drag her back down real nice and quick with compression braking if you keep it up in the revs. Makes it easier to be smooth and you can stay off the brake more. You shouldn't worry bout hurting her. Whip her like a rented mule and shell lap it up and beg for more. Just make sure you have good positive shifts when rowing through the gearbox so you don't hit a false neutral and over rev her. It'll happen.

        My ZRX is a bit different, I started out riding it like I did my 1100ES and found it doesn't comp brake as hard, and above 7.5K she will get away from you really quick. So I keep her between 5 and 7 usually. But very similar otherwise.

        Select you line, feather the brake, select the gear, body inside the chassis, head down, point the chin, aim for the apex, throttle up just before and steer her round with the rear tire. Mmmm can't wait for spring

          Go listen to a Formula One race, then ride your bike.

            Spin and grin!

            Ride along on my 850G getting a bit of exercise.


            I touch redline during the pass.

                  I buried the tach on my 1100 a couple times on missed shifts, the numbers go to 13k or so I think
                  Never did any damage, she took it in stride, never missed a beat, but, Thats when I decided to get the rev limiter

                    The 850 sounds real nice ! But you Americans sure ride slow compared to us Aussies !

                      Another one of Brian's video's (?) Sure sounds/looks like it.

                      Ride along with Brian on the 1983 GS850G on SR135 in Brown County, Indiana on March 20, 2010. That's Tim R. up front on a 1982 GS850GL.

                        The fisheye lens makes those turns looks not as tight as they really are. Believe me, having followed Brian a time or two, he's plenty quick.

                          The issue of over revving varies from model to model. The early GS750-1100's use a roller crank. Once you get much over 10,000rpm the bearings stop rolling and start sliding - and that creates wear. With high RPM, you also run the risk of valve float - where the valve spring isn't strong enough to return the valve before the piston catches up with in and trashes it...

                          The later GS's used plain bearing cranks - these you can spin a little higher. The 4-valve per cylinder bikes also have lighter valves which return quicker.

                            i too it out today and flexed its muscle a little bit. Bout 7000-8000 rpm, felt pretty good.

                              Until I fixed my tacho last year I thought I was really winding out my then new to me GS750. Coming off of a Buell XB9R 6K rpm was a lot. Then I fixed the tach (the PO said it has a new cable, ummmm no) and realized I hardly got her to 5K.

                              Needless to say the first time I wound her to 8-9K I was in for a treat.
