Re: Honda CBR 250R

Guys, A rubber thing which supports the chain to glide over it has come off. I suppose its stuck on the swingarm(?). Will it be replaced under warranty ?

Re: Honda CBR 250R


its a rubber chain slider.. get a new one.. costs 112 bucks.. replace it at the earliest.. else you will be enjoying very musical clinging sounds soon...
if your bike is just a cpl days old.. then yes... fight your lungs out and they will replace it...

else not an expensive part..

Re: Honda CBR 250R

Bike is little over a month old...enjoyed the music already . I went on a long ride yesterday(~600 kms ) and by the end of the trip this thing came off. I hope such things doesn't keep happening orelse it will keep my confidence shooting to take it further long.

Re: Honda CBR 250R

my first slider blew off at 1300km since then its been 14,000 now the second one is going strong..
the issue is.. it connects to the swingarm with mere 2 small rubber mounts.. so you never know... but not a known/regular issue... just one off a case...

Re: Honda CBR 250R

my slider too went off at ~2000kms. ASC didn't have a spare one, did a jugaad with a ziptie. Has been going good ever since, haven't needed a replacement yet.

Re: Honda CBR 250R

I got the kraftwerk frame sliders installed for my bike today at dsg. Seem pretty sturdy.

[MENTION=49917]bbsrailfan[/MENTION] I observed the issue of the tank being mounted a bit loose today. Crossed 500kms so pushed rpm till 5.5 and right between 5 to 5.5 there is a lot of vibration that kicks in which causes the tank (front left side for me) to start rattling. It sounds really annoying.

Re: Honda CBR 250R

Sent from your CBR? Good one buddy.

Pardon my ignorance, but are sliders really put there? How're they going to protect the front portion in case of a slide? I thought they're placed in the highlighted location.

Re: Honda CBR 250R

Hello friends,
This is a follow up of my CBR experience posted earlier.

TIRES
18100 km @ Tyres Shoppe, Sec 16, Noida, UP on 11 May ‘13
Cost incurred: [Total: 5800 (incl fitting)]

[At the time of writing this (18 Aug 2013), Honda has started shipping 2013 model CBR250Rs (few among regular colors and all Repsol models) with MRF rubber. Front and Rear are Zapper FY 110/70 - 17 and Zapper S 140/70 - 17 respectively. Just to remind you, Zapper FY and Zapper S were the tires used in R15 V1 which got rave reviews. More on the same @ MRF website. If one is looking for buying replacement tires, you can choose these with eyes closed; but availability would be an issue.]

Front: Pirelli Sport Demon 110/70-17 @ INR 2700
Rear: Continental Conti Go! 140/70-17 @ INR 3100

The change of rubber was a long time coming. Even though both tires were still about 2 mm shy (at center of the legal limit of TWI (Tyre Wear Indicator) and could have crossed 20k mark, the wear pattern pretty much renders them useless. All very well saving few bucks of rubber left on the tire but a bit pointless if it's at the cost of confidence. The tires get squared off and wear into pronounced asymmetric lips (It all starts getting pronounced about 9k kms on wards which causes undulating ride. But since the wear happens gradually rather than suddenly, one does not really notice things getting worse. It is only when it started behaving badly in wet and corners, I decided for a change. And what a transformation! The bike suddenly feels lighter, more purposeful, and more nimble. It turns in much more precisely, and has become a capable street bike rather than a boat - and I hadn't even noticed it becoming a boat!

Squaring off:



Unless you ride different bikes, it's difficult to feel the difference a squared off tire makes, as it wears gradually and you don't notice the change that much. However put the new tire on and it feels like the bike just falls into the corners!
The squaring-off phenomenon will always affect bike tires because of their design, but if the bike is being constantly ridden on winding roads squaring-off will take longer to occur, meaning extended tire life.
If tires are under-inflated this will cause squaring off, as would running them over-inflated but then the width of the ‘squared band' around the tire would be narrower as the contact patch would be narrower in the first instance.
Tire design means there is no cure for the squaring-off phenomenon, but once they're aware it might happen, riders can adjust their riding accordingly.

My Hunt for tires in local market in Noida yielded non availability of major brands (I hear Karol Bagh is a great place for bike accessories in NCR but I didn't check it out due to time constraints). For front fitment MRF, Pirelli and Conti were available while for rear, MRF Zapper Q and Conti were available. I selected Pirelli at front to find what the fuss is all about and Conti at rear as Q is tube type. Pirelli is from grey market, non ISI marked, (3010 week: 30; year: ‘10) manufactured in Brazil. Conti is (2812 week: 28; year: ‘12) manufactured by Metro Tyres in India. Stock size was the only option as bike is ABS equipped. I would advise all owners who wish to change rubber to get the fitment done at a professional shop like Castrol Bike Zone (who may also have wheel balancing equipment) rather than the same morons at the tire shop who usually don’t even have a paddock to support the bike and might end up damaging disc alignment (or sensors for C-ABS) even though it means you have to pay fitment charges and carry the tires. But, I got mine done at the morons!

FIFTH SERVICE
18185 km @ Prakash Honda, Noida, UP on 13 May ‘13
Cost incurred: [Total: 5552 (incl VAT)]
Engine Oil: 752
Oil Filter: 277
Oil Filter Cover: 70
Gasket: 0
Disc Pads Front: 1861
Disc Pads Rear: 1240
Heat Shield/Muffler Cover: 526
Steering Stem Nut: 39
Coolant Top-up: 0
Labor: 787

It was the first service during which I was present throughout at the SVC. After the camshafts and rockers were changed and valve clearances set at 17k kms, bike has performed flawlessly so far. Touchwood! After the service, there returned that usual eagerness and deep exhaust sound. As most of the cycle parts have been replaced recently, bike feels as good as new. Again touchwood! I have replaced disc pads twice and both have lasted about 9k kms. Both times, rear had another 0.5 - 1k odd kilometers left while front seemed good for another 1.5-2k kms but I replace them in tandem. Riding in NCR takes its toll; you have to squeeze through traffic jams when pressed for time and in doing so muffler cover/bar end weights/levers/RVMs take the beating. (Classic example: (No offence to anyone intended) When there is a Splendor in front of you and an Activa on your toes and you’re sandwiched in between on a CBR or a Ninja for that matter; and you’re making your way squeezing through traffic, people expect you to move on through the same space as they are moving. In tight spaces, sometimes either you let the Muffler Cover or RVMs take the beating or you face the music of blaring horns!). Steering Stem Nut on the first batch of CBRs is plastic and metal combo while now it is fully metallic. Change if you like. Just before the change of tires, FE dropped to 30 kmpl; haven’t recorded afterwards.

Another thing I wanted to share is about riding habit: up-shifting points.
Here’s a video of a CBR250R street ride in New Zealand
The person shifts at 6 - 7.5k rpm, i.e. meatier part of torque band. I have gradually started to up-shift at higher rpms, it keeps bike in power band and there’s no lugging or hesitation on the part of engine to move forward. To help decipher which gear one is riding at particular point by looking at rpm and speed, I have calculated kmph/1000rpm values of CBR250R for all gears:

1^st 4.659
2^nd 7.335
3^rd 9.884 ~ 10
4^th 11.908 ~ 12
5^th 13.926 ~ 14
6^th 16.141 ~ 16 (@5k rpm in 6^th gear, speed = 16*5 = 80kmph)

The values can be calculated for any bike and any gear using the formula:

3π(Dia of rear wheel in inches*2540+2*width of rear tire in mm*aspect ratio of rear tire)
Primary Reduction*Secondary (or) Final Reduction*Gear ratio*5000

For eg, CBR250R, 6^th gear:

3π(17*2540+2*140*70) = 16.141
2.808*2.714*.962*5000

Epilogue: No Leh-Ladakh trip this year, maybe next year; not much mileage expected in coming months as I’ll be leaving my bike at home for my dad to drive around town. Also it’ll be first time that I’ll experience Honda service in a Tier III city, as so far I have been lucky to be in Tier I or II cities to enjoy rather satisfying service from Honda.

Re: Honda CBR 250R

[MENTION=41586]Divya Sharan[/MENTION], I too feel that slider is incorrectly positioned. @jhonmathews Doesn't it interfere with your knee movement?

Re: Honda CBR 250R

Those are specifically not frame sliders but engine sliders and they are attached with frame sliders in pair for additional protection. . Alone they arent of any use.. infact in case of a fall.. these will put more strain on the cone set and clip-on

Re: Honda CBR 250R

Haha. What can i say? Its a high end bike. Lol
.
Yes they are supposed to go there but these will still protect the frame as well because it lies right in line with the center of weight ie the engine so it shouldn't topple towards the headlight side in case the bike falls on them. Also, the one I bought was definitely meant to be put there because it had the appropriate notches.
The ones you're speaking of are the yoshimura sliders and are mounted in a different way.


I'm not sure about them being of no use since they are placed appropriately in line with the center of mass. That being said, he did mount it by removing a screw from the rods of the frame under the fairing and attaching the slider frame and putting it back. Then the cylindrical part was screwed on the slider's frame.
I can't judge as appropriately though so I will be posting a few more pictures from different angles.



Not at all.

Right nest to the pipe you can see the slider's mount.

Re: Honda CBR 250R


Bro Pirelli front & Conti`s for rear is also good combo as new batch of conti`s is supposed to be made using soft rubber as per forum bros.
Also what oil your ASC is using @ 752 ? Was it Honda Throttle ?

Re: Honda CBR 250R

This is where most of the sliders go..





Most of the frame sliders fit at the Centre of the fairing.. However again there are types available..


Close to one year of ownership.. the first disaster struck today.. I was happily tailing a swift at 20's and some f****** up aunty on her super powerful activa riding around 50's .. rear ended me with a bang...

And license plate , left indicator and left footpeg gone kaput... I have kept her like no one else ever could... and it hurts... so much that in pain I even gulped a few drinks. ..

Irony is she says it was my fault that I was too slow on the road...

Re: Honda CBR 250R

Hi.
I don't know if I am posting in the right thread. If this is the wrong thread for my query, MOD please shift this post to the right thread.
I am planning to buy a new CBR250R. But there is something that is holding me back from buying it. Got very negative feedback from the owners. It seems it has a very high maintenance and quality is not upto the mark as it is an Indian make. My friends have suggested me to go for Duke200 which is better in quality and has a good service backup.
I posted the query in this thread so that i can get proper feedback from all the CBR owners.

Thank You
