    Yup.. so what rpm do u change gears on track?? I mean like if you change gears @ 9.5k rpm... then at what rpm does it come in the next gear (R15)?? Coz if it dips below 7k... it will take time to rev back .. and would lose time eventually....

    I have ridden P220 n R15 back to back.... on twisty ghats.... the both are very different machines... while u do better speeds on curves with the R15.... coming out of curves... it feels very very low...... while its vice versa with the P220. I guess its same with RTR (as the P220... with RTR's better handling package)

      The RTR is more forgiving than the r15 in terms of holding the power band. There's a lot more low-down power in the RTR and its an instant off-idle screamer even till the max revs almost, atleast 10.5k that is.
      The P220 would die out after 7k basically and only offers good low and mid. Top-end is never a highlight of the pulsar engines.

      I would shift the R15 at 10k or a little earlier than hitting that brick-wall rev-limiter. Rpm would drop to peak power by then which is still ok, which is 8500rpm.
      The R15 is sure a lot more peaky than any indian bike, although for its absurd bore/stroke its a weird character. Its cam-ed to run that way. A long stroke motor, trying to show a short stroke muscle, which is not its prowess. Its like a wannabe trying to be a super-star!

        Exactly...Couple of days back i ripped a R15 and i felt it lacked poke even at 4-5k rpm.It felt lively only after 7k rpm which i think is kind of weird for a road-going production bike.It would certainly come in handy in tracks but the exit speeds would certainly be a tough call to make as mentioned by chetan.

        The R15's high speed stability did impress me but the performance still leaves a lot to be desired coz the bike would easily withstand more power and it certainly 'deserves' it!!

          @Joel : You were at Chennai and did not give me a call ? I would have been at the tracks, if you had just told me...Make sure you do that next time around!

            That frame can handle even 30-40bhp. Only if it gets a really capable engine, it will be a real bomb. Will stand true to its YZF prefix.
            A performance bike is never expected to have much low-end, meaning nothing below 5k....ride a good sports bike and you'll know what i mean. All the power is reserved for top-end performance....but but, such machines will have a solid punch above in the power band.
            But this is weird.
            the bore/stroke of the R15 will ideally make the engine work as a low-end-mid range bike, but it runs a cam that makes it work after 5k. Which means, its worst on both ends. It gains a slight surge after 6k and then suffocates after 9.5k. Also the valve sizes are the smallest of a 4-valve engine. It would have worked best if the set-up was a proper short stroke. Thats why a CBR150 makes the best small engine SBK in true sense over the R15 even. or the FXR for that matter is a proper short stroke bike.
            Somebody just try an ECU with a crazily high cut-off and see what happens. It will indeed be real fun!

              Just tell me if the results will be positive and may be I will try to get one (Dont ask me from where)

                Put your engine on a dyno and then you can see that, the power will be dropping drastically. So its sure not gonna be positive.

                  Whenever i ride my friend's RTR-Fi, it sort of feels to lose breath if the revs drop below say 6k rpm at higher gear ratios, and absolutely pathetic to drive around town in traffic with a pillion because the bike constantly wants to be revved to derive even a decent acceleration, and i don't know, this may be just my feeling about the bike but somewhere in the middle (4~6k rpm) the bike seems to pause for a teeny second before screaming off, why is that?
                  I'm too intelligent to the unintended, and too dumb for the obvious.

                    @Joel: With the draw back you mentioned between the short stroke and long stroke engines, I still beleive R15 has advantage over RTR on track in stock trim because of the handling ability it posses, because after seeing the results on last race Group D expert category in which Vishwanath took comfartably win in both the races against the TVS factory riders.

                    Thats called ART OF ENGINEERING i hope

                    But no doubt that RTR is way better designed engine compared to the other bikes in the same segment.

                    PS: I am not a brand freak , even though the above post seems to be.

                      Wow lots a fun stuff happening in here!

                      Damn my office for not having access to xBhp!

                      Thought that I'd post quoting each and everyone's post here, but heck I don't wanna called a villian again!

                      But all said and done the the R15 no doubt a brilliant bike, but needs brilliance to be ridden! Which only a few on this forum can actually manage to do. The RTR/220 on the other hand are torque monsters (relative) which are a lot more fun to ride for daily riding. And isn't that what most us do 90% of the times with our bikes. IMHO!

                        thats what i personally feel toou might not wanna shift again and again in those pathetic jams which we have in delhi
                        Dont know but r15 has got something which pulls me towards itself

                          I guess a book on "Perfect way to rip/shift/drag the R15" should be launched by the 'experienced' members!!

                              Ok I wont ask where, all I am asking is, Can I get one too?

                              I have a RTR and I kinda know exactly what Joel is suggesting. I mean I dont deny that the R15 is a damn neat option, but its very boring for someone who has been ripping an RTR day in and out....

                              I am bored of waiting for the Ninja, and so if you promise to help me with a fkd ECU, I will get the R15 ASAP. (anyways I plan to book one @ Dasera )

                                No one can doubt that for daily commuting these are the best bikes..

                                No one on this forum was been gifted with the brilliance to ride the R15 the way it should be ridden, they all have learn't it from riding better bikes. The only way we can learn to come close getting perfect to what we love doing is riding a bike which teaches us lot of things we are not exposed to by the other bikes, say things like handling, breaking.

                                R15 is bike for whom its not just riding and having fun its a good learner bike IMO in every aspects. thats the reason i got R15, to learn, u see i am still a learner
