Honda CBR 250R

I dont have exact photos because it will require opening up of clutch cover.

But For reference it is this marked passage right below the bearing on which coolant pump runs



And here's the opening from outer side, from which oil seeps out. You can check that out in your vehicle as well.

Re: Honda CBR 250R

If you observe oil or coolant leak from this hole inside or outside the clutch housing "dedicated passage", that you've marked your bearings and or water pump seals are failing. If the mechanic isn't able to remove the bearings, a lathe guy can probably do the job for you. Inspect the bearings and get them replaced. Keep your observations posted.

The magic that you feel here is all numbers. The CBR is more a high revving nature as opposed to the workhorse that the Karizma is. Honda's tech, the best 10 years ago and still the bike does weave its magic amongst its owners. The CBR 250 makes 26 bhp and 8500 RPM and 23 NM at 7000 as opposed to Karizma where it makes 17 bhp at 7000 and 18 NM at 6000 and that's the reason you feel the reason you feel. The CBR does need to be revved hard to extract the juice, wherein the Karizma is all torque right from the word go, so that needs adaptation.

Most riders feel the frustration not because it's the bike's problem, but it's about how riders are not able to adapt to or understand what the motorcycle is all about. Nonetheless, the CBR 250 is a very forgiving and very capable machine, once you get to know to ride the motorcycle, it's a treat to ride the machine.

Re: Honda CBR 250R

Well I have the zmr 2014 so thats even more torque and bhp as compared to the older model, this one is at 20-20.. both torque and bhp.. so the rush is better..i can vouch for this as i have owned the previous gen zma too..

I currently own two bikes 200ns nd zmr..both the bikes are poles apart when it comes to power delivery..and i very well understand it and have very well adapted to it..i do not want to replace the karizma with a bike that has a power delivery similar to the NS..ideally cbr would serve as a perfect replacement for NS but im not looking for a replacement for NS at the moment..NS is a pain to tour on in hills..it is cumbersome to control, maneuver a bike which is revving at 7k rpm going uphill on a tight road full of bumps vs a bike climbing at just 2.5k rpm

Re: Honda CBR 250R


Then I doubt that the CBR would be the bike you would be looking at, its a short stroke, if you need a easy low rpm bike to tundle along then the royal enfeilds would be more suited, though it will not be a replacement for the ZMR.

But unfortunately as the market stands in the 250 category you got the CBR and Fazer 250, the Fazer is more practical in terms of it being air cooled and having a center stand, it is not a full performance bike [ lower power/ power delivery similar to the ZMR lack of the sixth gear] Further its tank is fiber, so magnetic tank bags are out of the question.

If I were you, I would rather upgrade to a 600 + CC machine as compared to another one of the similar category [ 200-250 single] or shift laterally [ go to a 300-400 twin]

Re: Honda CBR 250R

Hey, I'm planning on getting my first bike. I came across an ad for a 2016 ABS model (registered in 2017) CBR. It has run around 15000kms. The asking price is around 1.7 but I think I can get it for 1.5. Should I go ahead with the purchase? I'm going to use the bike mostly for commuting and touring once or twice in a month. I realise that I'll be better off with a 200cc in terms of city use but nothing in that segment appeals as much as the CBR. Am I looking at an unmanageable fuel efficiency in city conditions?

Re: Honda CBR 250R

Yeah! Even i was thinking the same but even if i get that bearing removed somehow, i dont think it would be of much help because service centre guys are simply refusing that any such seals or gasket exist behind it that can be replaced.
According to them no such seal comes for replacement therefore i have to replace the complete housing only.

Can anyone confirm this?

Re: Honda CBR 250R

Check the parts/workshop manual so you get a better understanding. Looks like the svc mech is bluffing around replacing the engine case.
Here is a very interesting explanation by a mechanic about the water pump seals. I think the cbr has a similar setup unlike the ktm's

Re: Honda CBR 250R

Thanks a ton buddy. This video was absolutely spot on. He has even mentioned that opening is present in premium bikes like honda, kawi unlike ktm for the user to know that something is wrong with the seals.


(Hearing respectful words for our machines was a proud moment though) [emoji2]

Even my assumption was similar that there must be a pair of seals, out of which coolant one is fine bt oil one has gone thats why i am finding only oil leaking out and not coolant.


Ill try to convince the technician for changing the seals in my next visit to asc.
Lets see how it goes.

Re: Honda CBR 250R

Different bikes have different water pump seal designs. As I've mentioned earlier, the Duke has two fragile oil seals and when the engine such as 390s produce so much heat, the seals just don't last that long. The CBR has an oil seal and another seal called a mechanical which almost resembles a radiator cap, only small. These are 100% replaceable.

Part number for the
Mechanical Seal: 19217-P72-013
Oil Seal: 91205-KF0-003

You can probably take these part numbers as a reference and head to your nearest SVC for more information regarding the availability of spares and their serviceability. Keep your observations posted.

Cheers!

Re: Honda CBR 250R

Many thanks to you bro.

Providing them with part number will make convincing them easier for me and reaffirm my point.

Otherwise they will just refute my request by saying no such part comes and bearing cannot be taken out.

Well, thanks to everyone for ur help on this

Re: Honda CBR 250R

Does anyone know exactly what the SVC does as part of the mandated service? Looking to save the 3k every 6000km
Service manual perhaps?

Re: Honda CBR 250R

I have a picture of the company recommended activities for the third service, that should give some idea.

Re: Honda CBR 250R

Good lord, is this it?

I do that on a normal Sunday (excluding oil changes of course).

So where does the money go, they really charge an awful lot.

Re: Honda CBR 250R

I am planning to change my front tyre, am considering pirelli sports demon nd mrf revz c1 . Tyre shop guy quoted me rs2500 for pilot street radial and 2900 for mrf. But in amazon its only 1800 for pirelli. Looking forward to your suggestiones

Re: Honda CBR 250R

The Pirelli would be 3 years old I think. I'm not sure about long term effects on tyres, but I would stay away if I were you. Get a fresh batch of mpsr. 2018 manufacturing.
