Here, we have honda claiming 135kmph, which doesnt seem very hard to reach(i mean reach, not holding it for long) for this beauty. Definitely i was missing something. Purely from engineering point of view, I was curious to know and understand whats honda doing here. I thought what better place to ask, than the ownership thread. What is the gear ratios for the CBR250.
    There're 2 ways to claim things; let me make it simple
    1. USTC- Under Standard Testing Condition
    2. Reality

    Using #1, there're are millions of IFs & BUTs; I'll have 1 litre of fuel, precise 1.5 litre of oil; SIMULATE the top speed on dyno with a "standard" 50 Kg person; when the wind blows from tail towards head; no RVMs - these are some examples & I'm sure one can find real innovative methods to tweak this.

    Using #2, there's only one way to test - gross weight of vehicle + maximum weight carrying capacity of vehicle & run on track/dyno

    On road, we all know, #1 doesn't work; and what happens when we have the data of #2 & the vehicle isn't fully loaded? That's why we have the question here!! Generally #1 is followed when company is following marketing techniques & #2 when they're confident about their products. This is also the strength of Honda & at the same time, their arrogance attitude they exhibit to their customers.

    Most of the times (I've heard this claim in Twister as well) I've seen HMSI being little pessimistic on their figures. I once had my Activa yielding 48 Kmpl while the company hasn't marketed the figure beyond 42 or something, which I remember vaguely. I'm damn sure it can give over 45 Kmpl when ridden within the economic zone, but, I've no patience to test that figure. Pls ask any HMSI showroom guys as what's the FE of CPR & they should say around 30 Kmpl; WE (not just me) once got a whooping 46.1 Kmpl from Ooty to Ulundurpet from morning 7:20 AM to afternoon 2:08 PM or so!!

    I'm beginning to feel these days that, this may be why Honda Motorcycles are more profound to be labelled as practical (add to that reliable) motorcycles to own.

      [MENTION=70997]emm[/MENTION], if you are looking to buy a motorcycle, the company claims should be the least worry. Often the owners have the best and honest info. As for top speed, my cbr250r does 150 in a straight road, and 154 on a moderate decline. Speedo indicated. Gears changed at 9500 rpm. Bike is Bone stock. Normal petrol. Light winds. Temperature above 30* Celsius. Rider weight 83 kg. Fuel around 6 litres.

        I received a call from dealer offering a pass for Honda revvfest on august 4. he said about the launch of 5 products including 650F. I hope new 250r/300r will be one of the other 4.

          to your query yes. now if you reduce one teeth at rear thats making it tall geared however the mechanism inside will still take same reading Ir-relevant of mods you are doing outside. hence if you were doing 100kmph at 6200rpm before even if you reduce/increase 1-2-3 teeth at front or rear. no matter what it will still show the same speed. so yes it will show less speed in simpler terms.
          I said it is OT as I don't own a CBR, I just want to know in general what happens. I own a ZMA-R and I have tried making the gearing taller in past by changing the rear sprocket to P220 sprocket.
          For ZMA and for most of the bikes the kmph/rpm changes if we change the sprockets. With stock sprocket ZMA does 100kmph at 6000RPM where as with a 38 teeth sprocket it does the same at 5500RPM.
          Is it different for CBR and why?

            CPR is no different; the speed/RPM differs between stock & altered sprocks.

              WOAH!! Thanks aargee for these insightful information. It was really really helpful. This is what i was expecting. Things are more clear now. There is so much to learn.

              Yes bro. the top speed will not decide whether or not i buy any motorcycle. Just wanted to clear some doubts i had in my head. Thanks for the imfo about fuel efficiency as well. I am eagerly waiting for the revfest.

                    for all motorcycles being produced since decades in india the speed is taken from front wheel hence if you make sprocket change and the rear tyre is experiencing a speed change more/less is also experienced by the front wheel which is visible in speedo. however but CBR and many other motorcycles that take speed from sensor inside crank-case so the outside mods do not alter the speed-rpm ratio. though real world figures get different. for this mis-match there are products like speedo- healer etc which can alter the value as per your choice and re-program it again.

                      Phew, that's one long discussion on top speed thingy, atleast it was not some occasionally popping yaahoo's saying he "smoked" someone or "ate my dust" attitude. Those were a real pain in the arse kind..!

                      BTW, just a query, I renewed my insurance last week, bike turns 2 in a few days, the estimated value of the bike is now at 1.06L , just wondering what is the value quoted for others who have hit 2 years or more.

                        i agree. top speed discussion on a positive note is always fine until its all bout mechanical working of the engine and machine as a huge diffrence between xxx's top speed vs regular top speed can help isolate underlying issues etc. however as mentioned the typical road rage stunters and racers kind of attitude is not at all good and should not be encouraged.

                        as for insurance i just searched for my cover note. 2014 my bike turned 2 hence the insurance was for the 3rd/running year.

                        manufactured and bought 2012.
                        2014 vehicle IDV as per my zero dip ICICI Lombard policy is : 107325, issued may 2014.
                        2015 vehicle IDV as per my zero dip ICICI Lombard policy is : 91993, issued may 2015.

                        hope this helps.

                          My 3+ yrs old bike valued at 85k. Thats because, I told them to do so(For less premium I have to pay). Original value was around 98K. United insurance.
                          The value totally depends upon the policy.

                            Thanks guys, looks like the evaluation is somewhat similar to what i got.
                            I never knew we could under quote a bike in insurance, does that have any effect on how much you can claim ? I would think the insurance guys won't let you under quote as it reduces the premium you pay up to them.
                            I am a total noob when it comes to choosing insurance policy or its techincality, i just pick a nationalized provider and stick to them. I need to get to know more of it.

                              Honestly, Its not a good idea to under quote. Incase of stolen bike, I will get 85k instead of 98k. And I saved a mere 1100₹ in last 2 years. But, during accidental claim, that wont affect anything. And always know, there is a scope for bargaining in every insurance policy. Just that, we dont know it and end up paying whatever they quote.
                              PS: Mine was a preowned bike, so wont mind, if I get less. I wont recommend it to You.

                                you can always reduce the value but also remember when you claim for parts/repair/theft or worse total damage you get paid less. its better to pay 600-800 extra instead of loosing 5-10k later. until first 3 years i assume you can go with zero-dip then until 10 years you can go with comprehensive and later only third party as i understand.
