Re: Honda CBR 250R
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?Originally posted by Dandamudi Mohan Krishna View PostLast edited by Harisankar; 08-03-2016, 02:10 PM.

Re: Honda CBR 250R
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.Originally posted by Harisankar View PostI thought ABS sensor works just based on the rotation of the wheel.

Re: Honda CBR 250R
yes, its from output of gearbox AFAIK. I know there will be slight change in the actual speed the bike runs.Originally posted by raja_ghuru View PostThe 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.Last edited by Harisankar; 08-03-2016, 04:14 PM.

Re: Honda CBR 250R
I'm very happy with the Michelin's to be honest. But my wallet isn't!Originally posted by raja_ghuru View PostSeems, the Michelins have given you extremely good mileage. Even if the procurement is on a higher side (cost-wise), the cost per km would have worked out really well for you.
Unless you are really unhappy with the performance of the Michelins, won't it be a downgrade in going for the MRFs?
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.

Re: Honda CBR 250R
you have MRF radial in stock 140/70 as well. no need to go for 150/60.Originally posted by Jon Niranjan Paul View PostOut in the market for a tyre change. I currently have the Michelin Pilot Street Radials shod, and they've served well for 32K kms! I saw a few posts about the NV series from MRF. 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.
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."A good long ride can clear your mind, restore your faith, and use up a lot of fuel."

The tyre you are talking about is zapper S which is a bias ply and not radial tyre.Originally posted by Deathwing View PostI 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 FE will get affected, that is true. Are you talking about the Zapper Q?Originally posted by theironhorse99 View Postyou have MRF radial in stock 140/70 as well. no need to go for 150/60.

Re: Honda CBR 250R
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 radialsOriginally posted by sanjaysangar1990 View PostThe tyre you are talking about is zapper S which is a bias ply and not radial tyre.

whole zapper series is bias ply whereas revz series is radials from MRFBurn the rubber, they said
it would be fun, they said

Re: Honda CBR 250R
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.Originally posted by Jon Niranjan Paul View PostThe latter versions of the CBR 250 came shod with MRF's. There is a 140/70/R17 available.

Re: Honda CBR 250R
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.Originally posted by sanjaysangar1990 View PostNo, the later versions of cbr250 are shod with mrf zapper fy 110/70 and zapper S 140/70.

Re: Honda CBR 250R
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 ?Originally posted by Harisankar View PostI 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?
Its not going to be a major difference but it will be slight.
