my fastest on road - 145 mph -> 235 kmph approx
Ford Mustang GT - US freeway

Hey RKS - i guess i could've pushed more but didn't want to - although the wider tires detract some speed (note speedo error is near 0 as tires are correct upsize) due to more surface area in contact with road, I would say the car was amazingly stable due to the higher grip and wider contact path This was useful as the road was not a straight, but slightly winding and not once did I feel the car as unstable and the need to let go of accel at bends at those high speed of 120-140kmph

Are you sure you did not mistype the speed also ?

My fastest so far is 205 in my Mitsu Cedia during the last tbhp meet on the toll highway around krishnagiri. Car was rock solid even at those speeds and didnt twich a bit.

@jassi, One more point which I forgot to mention: the Xing's top speed is achieved in 4th gear where it can apparently do a true speed of 150 kmph (could be close to 160 in speedo). In fifth gear the Xing's true top speed is about 143 kmph (as opposed to 137 kmph for my 1-lit Santro). I have actually hit 140 in 4th gear in my old Santro as well after upgrading to 5J alloys and stock-size tubeless tyres, but I haven't tried out the top speed in 4th. I keep my tyre pressures at 35 psi (because of my frequent Expressway runs), which helps in increasing pick-up and top speed to some extent.

5" alloys hehehe ok i guess you mean 15" alloys - so i was on 5th gear all the while never dropped and had AC on the whole while. Also I had nitrogen in my tires, which supposedly keeps em cooler or so i believe cos i read the nitrogen thread , lets not start tht discussion here now heehee

slightly over 180 during the recent yelagiri meet wasnt looking at speedo when i braked after seeing my passengers pale face

I meant 5J (I edited my post to correct this, but you were probably already typing your reply). The wheel dia is stock (13"). The wider alloys on stock-size (155/70) tyres effectively give me a greater contact patch plus improved handling and pick-up, probably at the cost of some ride comfort.

OR was it one Slopey highway? 180 on a stock Ikon 1.6,

metropolis ,
what tires are you running. am curious as I did not want to go over 160 on a flat road as I was on 165s.

IMO isnt that too much pressure which could lead in loss of grip? And at those speeds you need all the grip you can get.

At 35 PSI you would have uneven wear of the tire and tires are too hard to grip the road esp on fast bouncy roads.

Again In My Personal Opinion.

No not really the needle was nearly touching 180...........u have put me in a doubt hope the meter was fine but it does'nt seems abnormal figure as I have been touching 150 often

They were 14" tubless............it was down slope

i fell it because a fellow bhpian has driven it and wasn't able to go beyond 95

BTW were you on a slope

No it was a flat plain road, no slopes at all. palm beach road in mumbai, bike was howling as if the engine would go kaboom any moment

[zeeshan suleman]

Also just to let u know if you ride a new activa it reached 100 without any difficulty.

I find the grip to be adequate in dry conditions and the roads are very good. There has been no uneven wear for close to 20000 kms now. I believe the reason is that I do the Expressway at high speeds (120-145 kmph) every week and this driving style, with a lot of hard cornering, will tend to be hard on the shoulders of the tyre at normal tyre pressures. The higher tyre pressures compensate and keep the wear even. The car's pickup and handling improves significantly with the higher tyre pressures on my 5J alloys. But it is definitely not recommended for normal driving and in wet conditions.
