    I think its all in the geometry of the bikes, suspension setup, wheelbase and CoG of course.

    • ^^^ Actually wheelbase and suspension setup is to aide your centre of mass so it's basically tuning to get the balance between the centre of mass and the centre of gravity right, for the bike's handling dynamics

        • @all ....i believe, the new ug3 has low ground clearance than the v1 and v2 hence the 180 is damn good at corners exceeding 90....you need to get the suspensions adjusted to softest setting...and the rear is just perrfect...arrey i have pushed it above 90 in ghats yaar! you shoukd see the RSA guys in mutha ghat(correct me if am wrong) !.. the low and the mid-range torque(in the stock) makes it fly to 90, hence leaning out of the corner is fast...I believe its not about the ride its about the rider...obviously coz, the angle,speed, and position of your body wont be decided by whatis the rebound rate of your bikes suspension, but purely by your skills. the pulsars are known for handling..

          thats a very dumb theory, considering the kinda talks in your posts..obviously lower the centre of gravity, better the cornering!!! whats that gotta do with weight?? the F1 cars work on the same logic, extraordinarily low, cornering above 200!! very light...

          • @Kriss: No worries, we'll talk next time then

            Yeah the grid positions are a bit of a joke, there should be some sort of qualifying to decide that. For me its ok and till now i've been starting right at the back of the grid, but for riders fighting closely with each other its not fair to have random grid positions, especially in a 3 lap race. Anyways, i guess they dont have time to do qualifying with so many riders on track.

              Well my friend then i think you should visit the tracks here and have a go at the corners with the P180/P200/P220, you'll see that at the very first corner a TVS is able to exit the corner at a much higher pace (i said pace not speed) than you, and my theory still stands in lot many cases, if your mass is more centralised then in an corner you'll find that the lateral forces act downward on your springs making it more planted through the corners, this depends purely upon the mass of the bike. Don't mix bikes with cars, they both are in a different level. And the more soft your spring is, the more the rebound rate it too, and therefore in the middle of the corner your bike will needlessly wiggle due to spring rebound rate, that's why racers have dampers up front and rear is adjusted at full stiff so that the bike doesn't dive at every entry

              • @me is rossi - Dont know about the new pulsars, like you say i hear they handle pretty decent but in the past pulsars have just been a flop on the track, poor handling and gearboxes just breaking down on the track when pushed hard. I know about mutha, the ghats are nice and everything but nothing compared to the speeds done on the track. Ask speedy, he will confirm that himself as he has raced on both. Somebody should bring a new pulsar to track and have a good rider test it out, should be interesting.

                  Get it to the track and try it once.. Ghats is different from track.. No one is saying that P180 will not take corners above 90Kmphr thing is the with what ease RTR's and yammies can take its not the case with P180

                  • ^^ Not only that irrespective of how fast you enter a corner, the exit is always slow due poor power delivery at the high-end, all Pulsars have their powerband slotted in the low and mid-range making it easy for the street and highways, not for the track

                    P.S.- And FYI i have a P200

                    • BIKE INDIA had done a track comparo. I am sure most of us have read it. The R15 and RTR-Fi handled awesomely on the track. The ZMA and P220 were more slower around the tight corners. One of the riders even said he had posted similar lap times as a P220 on his P200 due its better handling characteristics at a track.

                      Here is the link:

                      • The biggest issues show up particularly when steering into the corner, lazy bikes like the pulsar will do well in the ghats through turns where the bike is smoothly banked in, bikes dont get unsettled much that way. On the track you go from totally upright to knee down (max lean) in half a second (atleast with a good rider) and all at very high speed. Thats where handling deficiencies you dont see otherwise start showing up. The dynamics are different on track

                        • @pranay- ^^+1 and also primarily because the frame neck of the 220 is thicker to accomodate the bigger fairing whereas the 200 has a bit thinner one, therefore the 200 is a bit deft to handle than it's bigger brother, but it's by no means nimble.......not even close

                            definitely. Agree to that. TVS had dominated the tracks and it shows on the RTR handling. I don't have to say anything about the Yam.

                            And thats cuz the 200/220 pulsars are fat a$$es. Bigger tires, bigger exhaust will not help you at the track.

                              This is the most interesting fact I've ever come across. I've just slipped off my chair now, reading this.
                              Having ridden a pulsar once in the track, I know how well it handles.
                              You might wanna come here once on your pulsar to only see TVS Victor 125's casually taking you from the inner and outer. Forget an RTR or R15.

                              Also your theory says that you need to run the suspension in the softest setting. GOod, you can very soon feel that your in a boat than a bike around a corner. You can get washed out.
                              Lets not compare ghats with a race track. You need to come down here to believe what we say.
                              Pulsars have low and mid power only. On the track, you need power higher-up. Which already knocks the pulsar from the list.
                              It would be begging for mercy at rpms above 7000-8000. Thats were bikes like R15 and RTR continue to make more creamy power. I hope you got the picture now.
                              Also P180 does not have a racing class as of now. Its slotted under a FMSCI specified 165-210cc....but there are no entries in this class whatsoever. Heck even the Group D 210-250cc class is abandoned.
                              You need the right machine to hit the track and pulsars, I'm sorry to say are simply not track worthy.
                              Speedy (Varad More) owns a P200 and he has extensively ridden the R15 and RTR on the track. he can vouch for the difference.
                              Frankly the pulsars do not fit anywhere...streets nor race track. Its slotted somewhere that I havent figured out still.
                              However the P220 and P200 are better handlers than the previous lot. Thanks to the revised suspension and steering modifications.
                              However, when you hit a corner....they stand no chance.
                              The best 5 handling bikes in the country in an order are,
                              *R15
                              *RTR
                              *CBZ X and CBZ
                              *Apache 150
                              *karizma

                              Its even more surprising that a few 125cc bikes outclass the pulsars in the handling department. The yamaha gladiator, Victor, Stunner etc are a few.

                                Which Victor 125 are you talking about?? GLX or Edge(may be they have the same setup, i don't know).But what i know is the Victor110 was the star of the track-in-its class.It did give the Yamaha Crux sleepless on the racetrack.Mid range grunt and brilliant handling are the forte of the Victors!!

                                Sorry, I couldn't resist myself from singing-the-victor tune!!
