Re: Honda CBR 250R

Correct me ADV bhai, 135 kmph must be precisely 8437.5 RPM right? I'm not sure if the OP should do such speeds.

Re: Honda CBR 250R

Absolutely bang on Divya bhai... as always. I read it normally as somewhere close to 8.5k RPM but that looks exact.
[MENTION=67135]coolhunk[/MENTION] For riding gear, ask around here - http://www.xbhp.com/talkies/universa...rs-thread.html

And for company, dont just look for CBR owners... maybe you ought to join up with xBhp Pune guys on their thread... highly likely you'll find people from Nashik in the forum itself.

Cheers.

Re: Honda CBR 250R

What's wrong with 135kmph as long as the OP is not thrashing his engine by sudden/over acceleration and/or sudden deceleration and as long as he is not keeping the engine pinned at 135kmph constantly for a significant time? I touched 128 kmph just a few hours after taking delivery. It took me long to get there, with a very steady acceleration - but didn't affect me one bit, even after 12000 kms into the ownership.

You kidding bro??? 5000 km...seriously? Run-in is over by 500 km itself!!!

Re: Honda CBR 250R

Guys... i did 135 after the 1st servicing (run-in) and kept the rpm within limits (meaning not red lining)... i had to open up the bike a bit... n i think waiting for 5000km for this will take me more than 1.5 years by my rate of riding... hahaha.. (just kidding)

by the way, i really want to get inputs about the noises.... would be great help

Re: Honda CBR 250R

Nothing essentially wrong in 135kmph... Nothing essentially wrong in even pinning the right arm all the way up to 155 on your first outing... but running-in is a personal preferential choice too... I like running my bikes in progressively like we ran-in old bikes... what can you say i'm old school about that. I did take my ride to 9K rpm 6th gear after the suggested 500km run-in in the manual but I did it slow and after that I took my time with stretching it in a repetitive phased manner till about 4k kms and after that let her loose completely...

One more thing is that its not only about the suggested, stipulated, published thing called 'run'in'... for me, its like owning/riding a horse, my body and mind need to wrap itself around the bike, to its every grunt, sound, tinkle, whine, whizz and roar if you know what i mean. When I bought the bike a lot hindered me from juicing out that kmph aptly... Its like what you were talking about with the rear brakes... in this bike a higher brake bias to the fronts are the way its supposed to be, i was riding a bullet with drum brakes before... my braking style, my riding position, the way i kept my feet on the footpeg etc needed running in... because all that basically got the CoG slightly higher towards the seat whearas on this bike its rather low down in front of the footpegs and shins... and to actually get the top whack one has to get to a tank hugging race position to cut through the wind effectively as well as weigh your weight on the ball of your feet to transfer it down low... in the beginning i was nowhere close to getting there...

Its like this... you can squeeze the world and drip it down your throat or slowly lick it like a popsicle on a stick... and I dont mean stick to 80kms till 5k rpm... not one bit bro... Progressive is the way to go in my opinion when it comes to run-in.

Cheers.

Re: Honda CBR 250R

Divya bro, how did you manage to get such a precise rpm in an analogue tachometer.

Re: Honda CBR 250R

Simple mathematics.

RPM figures in 6th gear.

80 k/h -- 5000 RPM
96 k/h -- 6000 RPM
112 k/h -- 7000 RPM
128 k/h -- 8000 RPM

In essence, in 6th gear, every 16 k/h increases the rotations by 1000 units.

Re: Honda CBR 250R

Beautifully said, and a much better way to put it forward.

Most people with a new bike are paranoid about the run-in (So was I, before I took delivery). It is up to us, the experienced owners, to give a non-confusing, ideal advice to any new owner. Tips like don't exceed XXX kmph and xxx RPM in Xth gear are really not helpful. Something which has worked well on my CBR may or may not work fine for a new CBR. Instead, new owners should be guided to feel their new bike, get used to the nuances, understand the behaviour and judge accordingly. If someone would ask me, there are only two points to keep in mind during a run-in:

Use it, don't abuse it.
Too much of anything is bad.

Like you said - one can take it to 150 if he wants, but he should constantly 'feel' the engine with all his senses and make sure it isn't abused.

Or rather, RPM in 6th gear/100 = speed in mph. Multiply 1.6 to get speed in kph
And: RPM in 3rd gear/100 = speed in kph. Unofficial but verified by me

Re: Honda CBR 250R

Yup! Agree on the 3rd gear part! ZMR and CBR have same calculations due to similar gearing.

Re: Honda CBR 250R

Installed a pipercross panel filter in my bike last week.MRP RS 3750.
.

Re: Honda CBR 250R

Is it a high-flow filter, like the K&Ns?

Re: Honda CBR 250R

Flow rate is better than stock filter but definitely less than K&N,i had earlier used a K&N for close to 4000km but eventually took it off as i feared dust to be sucked in along with air,i have been using piper-cross in my other vehicle for last 3 years also i have a cleaning kit for the same ,hence it was a matter of personal choice.As far as i know it has a double layered foam.

Re: Honda CBR 250R

New posting ride!

I was posted to Sri Ganganagar in Rajasthan. So, rode from Rajkot to Ahmedabad, parked the bike and gear with a friend and Volvo to Pune for some leave.

21 Jan was Ahmedabad to Jodhpur, 22 Jan - Jodhpur to Bikaner
23 Jan - Bikaner to Sri Ganganagar.

894.5 kms in 24 hours riding time. The entire route comprises multiple diversions and old patches in the first stage and patchwork of shoddy repairs in the second and third. This greatly reduced the avg speed to just 37 kph. The fog was another detriment.

The bike performed perfectly. No issues whatsoever. Max speed reached was 102 kph in spurts, for a few seconds or a minute. For me the bike is too light to take to higher speeds. Also, the brakes are not powerful enough to reduce speeds safely. One large pillion bag and a pair of saddle bags plus a tank bag added stability.

The 15 T front made life much more comfortable than the default 14 T.

The only discomfort I had was aching thighs. I guess I have got used to the "sports tourer" postural demands of the bike.

Hi [MENTION=49216]gopakumar s pillai[/MENTION]
Did you find any change after installing?. On performance, efficiency and sound..?
Thanks.

Re: Honda CBR 250R

Anybody here using the full system exhaust from akrapovic ? ie.. the slip on and the header pipes ? and if yes, are you going for a juice box or tuning box to complement the changed fueling maps ?

Any pointers on this will be much appreciated. also the cost involved in getting the setup, are PRS the only dealers for the exhausts ?


Cheers
