How quick should we change gears ?

    The trick is to find the max speed in each gear before the bike stops accelerating. Once u figure that out, remember to shift the gear slightly earlier, just before hitting max. rpm rev the bike. This way you won't experience too much of a drop in rpm.

      remember one thing dont revv too hard in the 1st gear keep it at 6k to 7k then get most out of the 2nd gear and then cross the limit in third..and not to forget do not go beyond 9k or u will end up in the garage...!

        @nox : y not rev in 1st?? i dont see ne sensible logic behind this...

        and u say not beyond 9k... now lemme count , how many times hv i taken my zma beyond 9k till now..
        taking into accound 10 times per day , dats atleast 1420 times!! n i hv still not ended up in a garage..

        also wat abt machines like kawasaki balius , which have their red-line at 14k ??
        u can define a limit to revving.. it depends from machine to machine

          wht u guys do 2 reach top speed in a short distance do u guys drag each gears or go 4 the perfect shifts

            on my bullet.. where there is no luxury of RPM meter...i shift by hearing the exhaust. 1st - 20-25, 2nd -40, 3rd - 55-60 and 4th 60+.. this is when having a street race with a pulsar. otherwise it is 20-30-40-50.

              hey i have got a 180 dtsi and i tried dragging it for max acceleration
              i do this for that
              0 -40 1st gear
              40-60 2nd gear
              50-80 3rd gear
              80- i didnt see the speedo for this but u go over 100 easily
              and the 5th gear took me to 127

                ~4500 - 5000 on a cbz, this essentially depends on the performance curve of your engine. its that graph which plots engine rpm with horsepower. just after the point where the graph tends to level out is where you should idealy be shifting for max pickup. to add to the complecation you must also know the speed ragnes on each gear as a function of engine speed. essentially you need to match your torque graph(thats engine speed and power) and your gear speed range to get the right ballance for max acceleration. for good fuel economy you need to stick to this same concept but you need to taper off the aggresstion. which means you need to take it easier on the throttle and stay away from the edges ofthe graphs.

                clutchless shifts dont messup any thing but they are capable of messign up your gearbox, i have cracked up a gear box and my dad kicked my rear for that.. i had developped a habit of shifting both up and down in my cars, and my bike i stopped it after a fat gearbox repair bill. i still tend to do it on a bike.. oh and i cracked up the gear box by mistake after over a years clutchless gear shifts

                    I was riding my dad's 14 year old KB100 RTZ before I bought the P150 dtsi, never had a chance to race the bike beyond 60kmph...
                    Now while taking the bike from 1st gear, how much do you usually have to raise the rpm before shifting to the next gear to get the maximum pickup ?!? how do we make the bike display its maximum power ?!? race it to its maximum rpm and then change gears or change the gears quickly ?

                    I was told by my friend who rode with Germans in Germany....they shift gears only after taking the rpm to the max in each gear. That is their way of ensuring that they exploit the potential of the bike to the max. Ofcourse the roads in that part of the world allow you to do that.

                      @vicky i have always get it serviced from the bajaj guys so as far as i know they put
                      the recommended oil..
                      @others hey after bunny wrote about the clutchless shifts i realised that actually while upshifting i dont use the clutch at all!!! ...its just a little blip in the throttle and the next gear....just used to do it unintentionally for faster acceleration.....but while downshifting i am not quite sure...and i dont see the need too

                        Well upshiftin.. it mite be usefull to do a clutchless shift.. but for a downshift

                        i feel it is better to use the clutch.. it gives better control over the braking.

                        for shifting up.. redlines where its at.. for normal street riding tho.. 5500-6500rpm is cool

                        on a pulsar.

                        @killer.. the downshifting thing.. i thot 'I' named it matching of rpm lol lol. So more ppl consciously use the same huh.. Good to know..

                          I've recently strarted clutchless downshifting a lot. BUT, no real performance gains to be had...i do it when i'm feeling lazy! Ofcourse you can do this only at higher speeds, or else it just causes your bike to jerk.

                          However, when i'm ripping it, which is most of the time, its momentary blips of the throttle along with simaltanious downshifts. Thats the best and only way IMO. Not blipping causes too much of a strain ont he engine as well as upsets the stability of the bike.

                          Upshifts are mostly clutchless, however on a classic pulsar, its best to keep pressure on the shifter, specially when in 5th gear, as it hops outa gear at times when you near the redline in 5th.

                            when the bike starts screaming...please have mercy and change the gears.

                              Depends on the rider

                              personally i dont think that there are any guidlies on when to shift gears...it actually depends from rider to rider. so if ur commuting on streets u would change gears at lower RPMs than while racing..similarly even in a race u'll be pulling the throttle like hell but u'll keep the cluth more used while cornering. The data certainly matters as whats the RMP at which u get max torque..in order to extract max power..but i still insist u should go by ur instincts on whats best for u at that time.
                              Just because you haven't seen it doesnt mean its impossible...expect the unexpected.

                                Bunny, m sure that this wont screw up your clutch plate but what bout the gear box, for sure you would be hurting it in the long run. The gears might just get worn out resulting in gear slips and false neutrals..
