    I thought ABS sensor works just based on the rotation of the wheel. How the width and sidewall length of the tyre matters? I thought ABS sensor on the brake caliper reads the rotation of the abs pulser ring and sends to ECU, and ECU activate ABS once sensor reads the wheel is stationary. Is that wrong? or Do you says tyre size matters since cbr comes with a Combined brake system?

      You're absolutely correct there. Tyre, sidewall size doesn't matter. The only problem is: if overall tyre diameter / circumference changes, incorrect speeds may be reported, coz, AFAIK, the speed sensor is based on the rear wheel speed.

        yes, its from output of gearbox AFAIK. I know there will be slight change in the actual speed the bike runs.

          Unless you are really unhappy with the performance of the Michelins, won't it be a downgrade in going for the MRFs?
          I'm very happy with the Michelin's to be honest. But my wallet isn't!
          Frankly speaking, Michelin's are overkill for my usage, i don't ride at a 30 degree lean angle all the time, the tyre's side patches are still holding good, the centre patch has squared off due to extensive highway runs, namely from bangalore to chennai.

          Curious about the MRF's because I read too many good reviews from the duke threads and forums from rather sane headed riders. And the other fact is that i've already experienced a lifetime on the Michelins, want to explore other options.

          There is a lot of space between the tyre hugger and the tyre, a 5mm increase on both sides doesn't make a difference. For punctures, I've been using PFZ for two years now, and haven't had any punctures till date. The bike has seen boulders, muck and gravel with the mix of city roads and black tops.

          My only concern here is, the MRF seems to be lighter than the Conti's or Michelins on paper, does that translate to a thinner tyre wall??? Anyways, will check and make an educated choice.

The front seems to be a direct fit (Revz FC) but the rear comes at 150/60/R17, duke specs. Would fitting a larger tyre with lesser sidewall affect the ride? Is it even safe to do so? And would it fit in the first place?

            Reason for the query is because i've seen a lot of good reviews in the Duke forum, and the price difference is quite large to consider as well.
            you have MRF radial in stock 140/70 as well. no need to go for 150/60.
            the over all tyre height is smaller by 140/70 by 6% . it will eat up your FE and increase speedo error.

            stick to stock size.. 150 mm i not the issue but the tyre height is. people are even using 160/60 without issues.
            MRF is available in 140/70.

              Aman bhai, where is that tyre. So far i have not seen any radials in 140/70 section from MRFs

              Zapper S is biasply
              Revz S is radial but not available in 140/70 specs.

                I have 140/70 mrf, its the stock tyre size of the r3, not all tyre dealers will have that size, I got mine from bm lal bros in chennai.

                  The tyre you are talking about is zapper S which is a bias ply and not radial tyre.

                  Mrf don't manufacture radials in 140/70 specs.

                    The latter versions of the CBR 250 came shod with MRF's. There is a 140/70/R17 available.

                    The FE will get affected, that is true. Are you talking about the Zapper Q?

                      Having said that, mrf are good budget tyres, serve the purpose, any day , Michelin is the best quality tyre suited for our roads, if I had the money I would go for Michelin radials

                        that is zapper s only..it is available in stock size. but it is bias ply type..
                        whole zapper series is bias ply whereas revz series is radials from MRF

                          No, the later versions of cbr250 are shod with mrf zapper fy 110/70 and zapper S 140/70. These tyres are bias ply and not R which stands for radial.

                          Even the zapper Q is biasply.

                          Mrf do not manufacture 140/70 specs radial

                            I'm on exactly the same tyres, zapper fy in front n rev f in the back, if I had 10k I would close my eyes and buy Michelin pilot street radials. Probably my next tyre change will be this. Guys I'd like to know in general how are Dunlop? Ive seen bigger bikes like kwacker 650 using Dunlop's... Not too many reviews too. I understand pirelli and metzelder are soft compound and are more prone to punctures. I read a comment that mrf is the answer as the poor man's pirelli.

                                Well entire ABS sensor calibration is done for the size 140/70 in rear and 110/70 in front so when you are changing to 150/60 the same calibration will not work exactly as intended ?
                                Its not going to be a major difference but it will be slight.
