Hi hayaz, from the requirements of yours the P135 suits good. But before you make your final decision I would like to tell a little bit more info about the SS125 since i own one. Since i never owned the other 2 i wouldnt make any big comments about them (although i did ride them).

First of all please read this Bajaj Pulsar 135LS Vs. Honda Stunner Vs. Yamaha SS125

The SZ-R is refined at lower rpms has a better torque distribution which makes it one of the best city bikes available. But its top end is not so impressive for a 150cc.
On the other hand the P135 is a pocket rocket & can smoke a lot of 150cc's currently available but bajaj reliability has always been a topic of debate.

Now coming to the SS125. It is according to me and other reliable sources (bikeindia.com etc) is the 2nd fastest 125cc at 108kmph after P135 at 115kmph. Trust me its damn good at corners & i have leaned it to a knee scrapping angle. The FE of it is also not bad when compared to the other two. The handling is excellent & the vibrations are minimal when compared to the other two. It does struggle till 60kmph after which it zooms till 100kmph. I dare to say that its the cheapest of the three.

As am way too lazy for typing See http://www.xbhp.com/talkies/531721-post1074.html

congrats on your ride. good to hear you're taking good care of your bike...

i'm a frequent visitor of The Bike Chronicles of India. also read the zigwheels review about the sz-r. sounds pretty impressive i must say. now with disk, tacho and bar end weights, its almost complete, but not fully loaded as the pulsars.. it is said that the roll in acceleration of sz is even faster than the fz. also, torque available at low rpms(which means strong low-mid range) sounds practical. off course at higher speeds i.e, above 85-90kmph the LS beats sz hands down. but one would ride at 60-70kmph mostly. what do you say??

Pulsar 135 is the best bet good performance and mileage too
And i have been having a 220 for a year now and i can tell it doesn't really trouble much.
and now that pulsar 135 uses newer tech. it's even more awesome.

Hi,

I booked Yamaha SZ-R and I will be taking delivery of bike next month 5 Feb 2011.

Its around 64 K on road in Mumbai.

Here it is in full demand. I was 23rd to book that bike.

Cheers!

PS: Please take my post as just as an FYI post.

I don't thik you will see such a shootout for a while. But you can go through the ownership threads (not sure about whether sz has one).
Or you can visit Payengs diary which has very informative reviews on both bikes.
BTW I completed 7000km on my P135 and it still impresses me on every ride.

Guys, eagerly waiting for a sz-r vs p135ls shootout....

p135 is a good option......worth the price and mileage wise its also better

saw a yamaha gladiator rs with r15 fairing today. that was looking cool. in fact, the fairing looked more at home on the glady when viewed from sides. neither i could notice other mods nor take pics since it was zoooming past me. trying to find it out...

on road off course...

60K Ex-Showroom or On-road?

Went to cheeran yamaha, trissur yesterday for test riding sz r. But unfortunately sz r will reach the showroom only after 4 months. But sz x was there. But all stocks were out of petrol (What a fate!). took my time to check out its design and build quality. The bike is solid, but doesn't give the feel that fz or ss125 gives, i.e, sz has a shining black handlebar unlike the anodised matt black finish of ss/fz. Switch gear is too not good. No bar end weights, no tacho(for a 150cc!), tyres are of tvs. Those i liked are the fz-like pilot lamp, aggressive stance, excellent paint quality with minimal stickers, etc. The ss and fz have many parts in common. They even share same footpegs. I felt that the 'feel' while holding on or even watching the ss is several notches above the sz (just according to me ). What do you guys say??

P135LS. is lighter, faster and very reliable.. I can vouch for it. Did 9k kms in 10 months before selling it.. as I was coming abroad. Never faced any problem with it.

Since you are already for P135LS.. just go for it. There is no need for a second thought.. other two can't compete with P135LS.. simply can't. Just think about it.. even the FZ struggles at 100+ speeds.. but not P135LS.. you don't need to believe this.. but just try test drive of both the bikes and see how they feel & behave at 90-100+ speeds. P135LS is an awesome bike.. just go for it.

After 6k the acceleration is high and also the engine sounds pretty racy.
may because the peak torque is at 7.5k. moving up to 100km/h from 70km/h is quite quick for a 135cc engine, I mean even very much praised 150cc engines struggle at that phase.

that sounds pretty reliable. What will really happen after 6k rpm?
