Couple of owners have reported damaged rear wheel speed sensor due to rear tyre change. Ergo, the CBR abs has a dual channel ABS. If the CBR has only CBS at the rear, then Honda engineers aren't fools to provide a rear wheel speed sensor.

All that combined braking system does is to apply even pressure on both brakes even if you press only one. CBS doesn't prevent wheel lockup.

Easy way to test it, is to slam the rear brake on the ABS model.

To make it clear for you. Yes, the CBR 250R uses Combined ABS, which means both the rear wheel and front wheel are connected and both will prevent lock up and work independently. The term combined ABS means, when you press the rear brake the front brake too is applied albeit mildly to aid in better braking, that's what the term "COMBINED ABS" means, combined braking cum ABS.

Now, there is something called DUAL COMBINED ABS, these are used for higher CC bikes where both lever and pedal operate different piston on different rotor. Bigger bikes have two rotors and two calipers in the front and rear, so the term DUAL COMBINED ABS.

In essence, what CBR offers is best in class ABS to date on any similar category motorcycle.

And did I forgot to mention, what a wonderfully calibrated system. Beautiful indeed.

Cheers!

I didn't have the doubt, it was shashank. Nevertheless, your information was more concise and always welcome.

There is high possibility that coolant level was more than required. 1500 km means first service should have been completed. Looks like fault from service center rather than engine.

A little more coolant will mostly only result in overflow from expansion tank and create a visual mess. it shouldn't be harming the engine.

Just checked his FB link that sums up. Looks to be manufacturing issue. Now a days with more fluids in the bikes we need to monitor coolant levels now and then. I feel sorry for that guy. But here are the question he might get from dealer or Honda and I don't see any relevant info in his fb post for the below questions

1) How did it work for 1500 KM with coolant leakage if the issue is there from day 1?
2) Was he topping up the coolant now and then in that case he should know how to check the coolant level and should have brought to the notice of dealer or Honda and stopped using the bike.
3) What about first service? any bills and statement of work done? While draining the engine oil did they find something unusual I know they will not allow you to servicing bay but this will be valid question for them because it is their responsibility to check that during break in period.
4) Speeds he was driving during run in period. Recently read about a TVS apache where engine got seized while racing during run in period.

Please don't get me wrong I am just trying to help that guy in case he follows this forum as he will need to have all this info presented to Honda in order to convince them that he has a legitimate warranty claim. I know it is emotional factor for him but for Honda or dealer it is pure business.

Hope he gets his issues addressed.

A bike can do a few 100 km with a gasket failure. we see plenty of ktm's that bust a head gasket and run just fine albeit the coolant disappearing until the gasket is replaced, and continue to run fine after that.
The guy has mentioned that he had bought it to the notice of the svc about overheating.. so it is the svc responsibility to identify the fault and not the owner to point out that coolant is missing etc.. etc..
As usual our asc (probably means authorized scam centers

) just try to rip you off and try to invalidate warranty claims with lame excuses.

I don't think there is a way for them to find out how the bike was ridden during run in, unless the ecu logs certain parameters like max rpm's / speeds etc.. which i don't think it does.
And yes some folks rip their bikes along with their buddies right from day 1, and this sometimes could lead to premature failures.

That's about as much we can speculate from the fb post. Bottom line, my take is that Honda has to fix this up under warranty.. either be it a simple gasket replacement, or head replacement (if its warped, which the guy says is), block piston and worse case an new engine ! We have a member here 'aargee' one of the earliest owners of the cbr who had his engine replaced under warranty initially due to a seizure. But to get that one has to be persistent and take it up with the manufacturer in writing and stop ranting on social media.

Completely agree with every point. I am just saying what kind of arguments he can expect from service centers.

Sounds crazy but I heard some time back that overflowing coolant was entering into engine head not sure how that was possible but was just thinking is that possible in this case. Anyway thanks for clarifying

Wow CBR still doing 11th position .. i am surprised.. guess a lot of good word about the marvel is around.

It was rock bottom due to the Bs4 taking a while to launch but now its back, quite decent considering, ppl expected it wouldn't sell more than 20 bikes a month.

Hey guys,

Was having a healthy discussion with a few friends about the C-ABS system on the 2011-2017 CBR250R, had a few queries-

1. Is it a dual channel or single channel ABS. AFAIK, dual channel ABS handles each wheel independently (correct me if I'm wrong), but some are saying it's a single channel ABS combined with CBS. I did read about C-ABS in the previous pages, but it confused me more.

2. Does the ABS prevent rear wheel lock ups on the CBR? I know this might seem like a stupid question, but opinions are differing. Owner experiences are welcome.

@psr @aargee @leech @prateek2210 @theironhorse99 @B7ACKTHORN could you please help me understand?

From the horses mouth:

i am just surprised by the numbers of RE 350- 52k + 13k ... what kind of craze is that....... RE is becoming BOSE of motorcycles.

Went ahead and installed steel braided brake hose from Pulsar 220 today and its a direct fit. The length seems appropriate too! There is enough slack and cable doesnt stretch even a bit! The SS hose cost me 1020 bucks amd the installation was straight forward without much hassle

Well, that's how it is. People know shrimps are full of ca-ca, eventually people consider them as delicacy. Well, there you go.
