Re: Honda CBR 250R

kindy read carefully what i said, i did not say that he did not carry out the repairs/replacements.. i only said that most of them will be unnecessary at 20k and mostly pushed by the svc to make a buck. if you look at his other video on his kawasaki he talks about the very expensive costs and 'unnecessary' part replacement recommended by the svc, maybe kawa bit him harder since their parts/labor cost is skyhigh .. so he goes to local wheel repair shop and gets a wheel bend corrected.

i was just trying to say that bajaj/ktm service costs are economical/at par compared to other manufacturers who make and sell bikes in India.
you know some guys use pulsar disc pads and fz oil filters on cbrs? a ktm/pulsar brake pad set (front and rear) together cost only around Rs.500, oil filter 75rs, fuel filter 100rs, air filter 250..
fz250 brake pads are around 900rs for the front alone, r15 coneset is around rs.3000, chain kit around 3000rs.

tires for these bikes are again priced more or less the same, so instead of being surprised or shocked do a proper comparison and math on the service costs per km especially on bikes made and sold in india. people in India just want a fill it shut it experience, but that my friend changes when you start buying bigger bikes and ride faster

imports like benelli and even kawasaki these days.. nothing but horror stories from customers. a friends n300 was sitting at the svc for 4 months for want of parts and that too just the cosmetics like fairing, brake levers and handlebar.. and an eventual bill of 60k ! a benelli 300 owner, went for a side stand replacement and was quoted 3000rs, damn he got it fixed locally for 200rs !

so educate yourself about your bike and general maintenance/service and save yourself some money by not being taken for a ride.

Re: Honda CBR 250R

I appreciate a healthy discussion about motorcycles and it's maintenance and happy to see the reply from you guys going in the same way. I love motorcycles and not a fan of a particular brand. But I want to stress again that Honda is giving a step motherly treatment for CBR owners in tier-2 cities and the likes. This is definitely not the case with KTM. My cousins friend waited for his mirror after ordering it for approx 2 months. There is only one service centre and it's highly incompetent and he is travelling to the adjacent district(70 km away) just to get basic service and spare parts. But, even after ordering spare parts there, he has to wait for minimumt 2 weeks everytime. That's highly disgusting and a sure turn off for potential CBR customers like me and my cousin. The bike may be competent and reliable, but there's no point in reliability if you can't get your spares and service with no fuss.

Re: Honda CBR 250R

honda doesn't care about the cbr owners they are happy selling and servicing activa's and making good money. they just don't sell (or even bother to sell) enough cbr's to keep ready stock of parts, which i guess is going to be worse in smaller cities and towns.
the way around is to ask your friend to place an order for regular spares/consumables such as oil/air filters, spark plug, levers, cables and collect them and keep it with him and use it during services. sometimes shooting a polite but firm email to honda customer service explaining your situation might expedite the arrival of parts.

no doubt it is one of the best and reliable sub 2 lakh bike around and i am not one to judge a bike by how long its been around or some fancy feature.. just as you pointed out unfortunately its the step motherly treatment by honda itself.

Re: Honda CBR 250R

Guys any idea what engine knocking is related to, my friend who rode my bike says its the problem with my bike and could be due to old fuel.

Re: Honda CBR 250R

can you explain what is engine knocking ?

Re: Honda CBR 250R

Has any one converted/attempt to covert a CBR250 R to a CBR300R

I was reading the thai CBR forums and it looks like the no of parts that are different from the CBR 250 to the CBR 300 is less than ten.

Has anyone considered doing this change?

Re: Honda CBR 250R

Found this online, hope it helps.

Re: Honda CBR 250R

I guess @nuda900r was talking about engine and not looks.

Re: Honda CBR 250R

He has given details about how he fixed the 300 fairing on a 250 and the associated costs.

Re: Honda CBR 250R

I said that @nuda900r was asking about transforming the 250R engine to 300R, and not the looks as you mentioned .
And for @nuda900r. Yes its very much possible to upgrade the 250R's engine to 300's, the 300 is a bored out version of the 250R, and provided you have the necessary engine parts of the 300R, you can easily do it. You may import from Thai or US and do the job, its a straight fit. Just some engine internals are different. Even the stator, battery, etc remains the same, hence eliminating electrical issues too. But first, you need the parts. HMSI themselves could have easily made it a 300r, but activa makes more sense to them

Re: Honda CBR 250R

Knocking happens when combustion occurs before the piston reaches the top most part of it's stroke to keep it simple. I think, the signature sound that all CBRs make at around 4.5 to 5.5k RPM or that stitching sound is not to be confused with knocking. Knocking is something you'd experience with any internal combustion engine when you lug the engine with high gear with extremely low engine speeds.

Cheers!

Re: Honda CBR 250R

how about the ecu/fuelling, throttle body, ignition, head/valves, camshaft.. not as 'easy' and also considering parts availability. not a practical option imo.
just sell the bike and buy a more powerful one, or go in for one of the performance upgrades offered by outfits like race concepts etc..

Re: Honda CBR 250R

Rightly said..Upgrading an engine from 250 to 300 may seem easy, but is not so even with stock parts..All of the parts listed by you may have to be included in list for purchase and in the end the cost will not be justified.
Please do not recommend Race Concepts as many times over they have been shown to be un-dependable and the owner himself had admitted the shortcomings of the concept.

Re: Honda CBR 250R

psr sir,

I got hold of the CBR250R and CBR300R parts catalogues. In my opinion, the following items have to be changed to covert a cbr 250 to a cbr 300

1.Crank shaft -part no 13000-K33-D03
2.New cylinder -part no 12100-K33-D00
3.New piston - part no 13101-K33-D00
4.Clutch springs - part no 22401-K33-D01
5.ECU - part no 38770-K33-D02
6.Cam shaft in - part no 14110-K33-D00
7.Cam shaft ex - part no 14210-K33-D00

The ECU can be avoided if you can get your old ecu tuned for the higher displacement

That's the total list of parts for converting a CBR250 engine to a CBR300 engine

The approximate total cost for the parts for this conversion is about Rs 33000 if the parts are brought in Thailand of which the ecu is about 9k

psr sir, you are right that this is not really cost effective. I was just considering this as a theoretical exercise

Cheers

Re: Honda CBR 250R

Worst case scenario factor in cost of a 300's wiring kit, sensors and also consider reverse compatibility in terms of sensor mounts on components.

Reason for saying so is that a fellow bhpian from the CBZ/Hunk thread went through a lot of trouble with spares of different iterations of the same motorcycle due to a silent wiring update.

You could retro fit wiring but then again at the cost of reliability.
