Having said that sometimes I feel that cbr requires one more gear like hyper drive[emoji14]to increase its fuel efficiency.

Lol.hyper drive.hehe
BTW does it have a decent fuel economy ?

Yes, those who are more into touring are reporting avg fuel economy around 40kmpl, sometimes in excess of 40. For city and highway mixed(like me) gets around 30+kmpl. Others reported less than 30 but thats more due to riding in traffic or little heavy with the throttle..

40 seems about right on the highways , range about 350-450km in the highways? 450 is pushing it but I think if u keep the bike below 7000rpm at 6th gear maybe its possible.

average FE of 40? what tacho range we need to keep to get 40 average? I think that highway ride might be so boring as it restricted to 5K rpm or below.

That's a very good FE for a 250cc bike I think [emoji4]

yes, extending the tank range will be an issue as the fuel gauge in CBR is not accurate, so one does not know how much fuel is left. so its safe to refuel when the per tank range crosses 300 to be on the safer side.

Aargee has once mentioned that it was very boring to ride the highway to get max FE, but a figure of 35+ in CBR can be managed without a boring ride.

Yes, its very good FE. But one should not get carried away and redline in each gear. This is one reason I get a little less FE even though my usage is less in city/traffic.

Below is the overall summary of my FE figures.

I don't think your weight plays a role. 25/26 ratio (for 6th gear) of CBR will never saturate unlike lower gears where engine rpm output will be higher and hence it will easily transmit it's torque and hence reaching max rev with your weight isn't a matter. But when you shift to final gear, where the output spin rate is now more than the input, which is where the engine lacks the enough torque to push you. That's one reason why we need a gearbox for gasoline engines :-)At 0.96:1 ratio, that's like when the engine spins 9600 rpm, the secondary will make about 10,000 rpm. So even when you run on full throttle, there is no way the engine will reach redline (rev limit). And the engine needs about 120% throttle to rev beyond 10,000 rpm but you can't provide from fuel. But there is only one way to provide, that is gravity :-) Try riding on a 30 deg slope...Kindly ignore if it's very basic :-D

Looks like cbr is the first bike in India to have a perfect gearbox. Typically, the top speed is achieved at max power rpm at top gear. Cbr has max power at 8500rpm. At 6th, thats the max it can achieve unless external forces come into play. In India, most bikes achieve top speed at the Rev limit at top gear, suggesting that the top gear is short.

Its available in playstore with the name "FillUp - Fuel Log".

The app is a simple calculator with log, where we need to enter the ODO reading, fuel filled in litters and the total amount for that fuel purchase. The hard part is this needs to be entered for every fuel fill done.

I mean , wat if I ecu tune and change the exhaust system... Will that allow me to redline and increase the top speed? Just curious, this is something I would experiment on if I get a 2nd bike which looks like the 500r if it releases here or the cb650f or a650cc as a tourer... I want to know, I've seen a few vids on youtube guys going 170-180 obviously modded

Please share the price and let me know where I can procure them from.

First of all sorry for the late reply as i was out and had no Internet connection 😡😳

I've been using Led's for headlights since a year now and have tried a couple of them and from my experience they don't generate alot of heat like the halogens do.

I bought it from opera house, Mumbai.
It was for 1600-1800 depending on what shop you look into at.

Ur saying it's better than stock halogens & Osram NB too??
Can u give the link for the product??

Yeah it comes with Driver, just like the HID's ballast but very small like probably 3inches long and 1 and half inch wide.
Yeah mine is plug and play.😊
From my experience and many night rides, i say it is better than Osram NB. High beam on the NB could be a little bit better than the led but that depends on the reflector's design.😷
I haven't checked out on the internet for these leds but i guess few mins on google would help you find a link for the led. 👍
If you're doing offline shopping then look at car lighting shops as this light was originally made for cars so they come in a box with 2 piece, A little talk could get you one piece from the dealer too 😉

Yes tuning will make the bike go faster since the gearbox and engine is not at maximum. The gearing allows for more speed when the engine is tuned for more power.

That's good to know.. I'm thinking of doing this if I get a 2nd bike for the weekend rides n touring, I'm thinking if fabricating a exhaust and tune the bike as per the exhaust, its a bottle cap exhaust too, I've heard there is full kit for 60k, not sure.

Re: Honda CBR 250R

OK guys I put my bike through a mileage test in city n traffic conditions. With mixed riding of the bike for a full tank got a tank range of 320-330, with revs mostly below 5500-6000rpm, a few times above 7000rpm, but very mixed, would like to know if these figures are good or bad? Highway Mileage I'd expect 350-400km comfortably for tank range or maybe a bit more.
