  • On a serious note , its not about the figure samarth . Pulsar revs till 10k on the meter , in reality oly till 9.5k. It shows ten on the display thats all. But u ll see it start to build vibes after six k or seven k . Zma cut off at 9.5 k. U knew that ??? Rtr revs till 12k . But have u seen how much of vibes it produces ? It starts feeling rough and noisy.(u like noisy bikes right !) . Thats not the case with r15 , even any gear red line it doesn vibe as much as any of the mentioned bikes .so u cant blindly judge a bike on its cut off range.plus on top gear none of the stock bikes hit rev limiter . Gearing is designed like that for safety reasons .

      Could you throw some more light on that? I've noticed that, and the max the 15 does is 9k in the sixth.
      Thanks

        Good to know... I was thinking, if ever the YamaLube is out of stock when I need to change oil (in Hyd only one Ymaha Svc Center had it last week), I can probably use the Honda Oil or Motul 3000 4T. Now the Motul is out.

        Of course, I now have a few spare cans of Petronas Sprinta 4T 5000 Fully Synth oil wiht me...

Could you put up the details with pics as I am unsure of which screw to adjust..
        Post 1063 and some posts backwards in this thread have some discussion about the headlights. Attached is a photo of the beam adjustment screw on RHS. Exactly similar one can be found for the LHS even.

        For P180, I know it's 10krpm. and R15 is red lined at 10.5k ... So, rev limiter at?
        Yes buddy.... on Paper the P150 is a much better bike than an R15. But then, did you ever notice that the class topper is usually not the brightest kid in that class???

          theoretically it can redline .. but you will need an immense amount of road for that at a favourable gradient.

          • FYI i think the R1 doesnt go beyond 13.5k ... so a P180 is 3.5k less revs than a R1 ...
            ^^ but of what use is this comparo anyway ?

            yes yes, the R15 doesnt vibe at all, its quite scary to see the speedo all of the sudden (when i was riding realredice's bike) "woah 110 :O f_aak"

            well im glad my cbz-x doesnt go beyond 8.5k the vibes produced at 10k would probably disconnect my arms and legs from the torso

              where's the attachment ?? And as far as I remember , most of the discussions revolved around HIDs.

                in the extra overdrive 6th gear of the R15 you wouldn't have enough torque produced beyond the peak torque RPM (7500) to push the bike forward cutting through the air to take it to the max attainable RPM on paper... for that matter, I guess any vehicle wouldn't have that much torque for the higher rpm's in the top gear!

                Check there again... there's discussion about headlights as well...

                  I've observed the same. Some time back, I had posted here cribbing about it. In case there is a slope, then only she crosses the 9k limit. That time, people had adviced me to cross 9k at 5th & then shift gear & accelerate. Even then, I haven't found out how that's doable. What I mean is I tried it once, but when I shifted gear, RPMs reduced below 9k, & then again, it was not possible to go speedier. I thought that I was holding clutch for a longer time, but I have not got time to give it a second try.

                  On a similler note, I want to ask a question... I owned a Freedom Topper in the past, & the experience was, I could always shift gears without applying clutch, if I was at appropriate speed. The same holds for R-15 as well. The question is, Can I SAFELY shift gear without clutch in the scene mentioned above?

                  Thanks!

                  • You're speaking of clutchless upshifts.

                    as long as its done correctly, its not harmful to the transmission.

                    The R15 has a toe shifter which has a certain free play, after which the transmission pops the gear to the higher one.

                    how i do it ill explain in my way (i do it on my cbz-x which has a toe shifter and the same gear shift pattern as the R15)

                    -have the toe shifter at zero freeplay (that is already have it pushed up with some force from the foot) this you can easily feel since the actual gear shifting force needed is more, there's a distinct end to the free play

                    -go beyond the minimum rpm necessary for the upper gear to be effective. the bike shouldnt be stalling when you upshift. have sufficient revs

                    -close the throttle momentarily, so that the "acceleration" load on the transmission isnt there, by this i mean that the transmission wouldn't be under stress when the bike's cruising rather than accelerating.

                    -upshift with a click. and then leave the lever unstressed (this has to be done fast)

                    all the above is done within a blink of an eye.

                    of course this method would be harmful if you downshift, because we downshift due to the need of braking for some obstacle, and if the bike remains at the same speed the rpm will go up a lot. will be , say a rough and bad thing to do


                    i don't know whether what im doing is correct or not, but i have my bike's transmission to stand proof that clutchless shifts arent harmful if done the right way.

                    this doesnt mean that you dont need a clutch lever. I usually upshift when im quite far from any other vehicle nearby to obstruct my way, in the city its quite impossible to have a relaxed situation where the clutch usage wouldnt be necessary.

                      I guess I am following the same procedure, except for closing the throttle.
