Sankar, I also downgraded. Not as much as you, but I learnt to ride on a Yezdi Roadking .

Secondly, I am also deciding tyres for my bike. Pulsar 180 DTSiV1.

Planning on M45s. 2.75x18 for front and 4.00x18 for rear. Some people are saying that 4.00x18 will become too broad for the rear. Is is true?

I thought 4.00x18 meant 4 inches was the width of the tyre. 4 inches is abt 101.6mm. Stock size is 100/90. So, it should be right.

Experiences

more than 10 karizmas with the sport demons on the rear 110 section successfully doing duty with insane grip levels for both cornering and braking.

M45 is good but due to pot holes the tyre looses its shape and there is noticeable
road noise which can be experienced from it.

Go for it if you can find 1....

Hehehe... so there are few downgraded members here

Ok, i've made up my mind. PSD at the back and IRC at the front! Now to find PSD, that's the hard part.

Ya its wider 4.00's equivalent size is 110/90..
The traction is good but ride is a bit bumpy.. I would not recommend this for the front...

I've had experience with PSD (110-section) on Zma with some issues-
Lack of confidence-inspiring grip in the wet due to the tread pattern design (no rain grooves). Same goes for light off-road conditions. Pure, dry tarmac grip is exceptional of course, but the fact is that our roads aren't race-tracks and ones without rain at that.

I've used Dunlop Geocruisers (the same that came as a factory fitment on the CBZs) but in 120-section on my Zma for over 2 years in Bangalore. Downpours, dry-tarmac and even light off-roading encountered during touring- it held up well. I was especially impressed with the wet-grip, those multiple grooves work well to eliminate water from under the tire, brake hard in the wet the rear will lock up instantly but will always stop in a straight line, no fishtailing antics. There isn't a 110-section available AFAIK and truly Zma's rim is a little narrow for 120 but had no choice.

One of my friends also used IRCs on his Zma (90/90 F) and (110/80 R). Super-soft compound, good for trackdays also but less life. Off-road grip is ok and good grip in the wet as well. Havn't experienced it first hand in extreme conditions so can't elaborate more.

From what I've heard from users, the M45 is insanely grippy, but is equally heavy too and will wear out very soon. If I remember correctly there was a CBZ in Bangalore with a M45 rear that couldn't get into a triple digit max-speed (tested on a Garmin GPS). Thats how much of a performance dent they make. And they aren't available as tubeless AFAIK.

Hi Sankar,

just too add to what doomsday has to say. The Geocruiser's are by far the best value for money that you can buy.

They have brilliant dry and wet gripping, the 120 should be perfect for your zma.

The M45 have awesome grip but yea, it will slow your bike down. So if you are willing to compensate, look no further.

The IRC is soft and has very less life. I am not sure about how it grips on the wet.

According to me, the Geo Cruiser is the best option as of now.

Cheers
Shrey

I've found PSD

Now the question: If i'm mounting it without tube as it's supposed to, then should i get a bike specific tubeless valve or will a car valve do the job?

From where to get this tyre installed in Trivandrum?

Bought Pirelli Sport Demon 110/90 18 (Pirelli Kali Bhootam.. lol ) and got it installed this afternoon. Btw now i'm running it with a tube, will shift to tubeless after some time.

Techno: Is the Sport Demon's sidewall stiffer compared to MRF Zapper's sidewall?

Car & Motorcycle tubeless valve stems are different, motorcycle tubeless valve stems are thinner. It's available and i saw it today at the tyre shop.

Slightly higher profile so gearing has become slightly taller, which i think is a good thing.


Edit: I still need another good front tyre. I think i'll go for the IRC as planned!

Also do they have 100/90x18 and other sizes like 2.75x18, 3.00x18, 3.25x18, 3.5x18 looking for my CBZ and RD.
Very bad experiance with M45 4x18 in my CBZ rear dropped the top speed by 10KMPH.But excellent grip.

Yeah PSD do come in 100/90 18 size but it's for the front wheel fitment. I don't know if it's available locally. Inch sizes are not available as far as i know.
