People, is it just me or a fact, I dont know.But riding the CBR150 and the R15 back to back, I felt the kick of power the CBR offered after 8000RPM was more pronounced than my R15 at 7000RPM. Now obviously, the R15 has a wider powerband compared to the CBR, so is it due to this, that the R15's power kick post 7k is a little bit less pronounced than the CBR?

The 150R is a crazily high revving bike!
It peaks at 10500 Revs vs. 8500 in mine!
But the riding position is awkward compared to my bike(especially since I love the riding position on mine).

My friend's Ceeber next to my Bike.

Yup, you got that right. Both R15 and Babiest CBR redline at 10,500 RPM. But R15's power band or whatever we call it, is spread across a wider range. The case with CBR150R is that it peaks up the moon and thus you get more kick up the rev range. And theoretically, CBR should give in more sense of fast-ness than R15. No debate here, but more power = more top speed. Power gives speed, torque gives acceleration. At least this is what I understand.

incorrect. There is a screw on the R15 to adjust the idling rpm.

Fact 2: Advantages of fi over carb is that it electronically controls the AF ratio wrt the ambient temperature and on change of altitude and thus prevents cold start issues (completely) and is hence slightly more fuel efficient.
As for the idle rpm, it doesnt control it but merely helps maintain it to its standard set value.

Absolutely, infact setting iRPM is simple DIY.

Thanks for the input on the matter mate, I was wrong the whole time

, now I get it, the idle RPM is easily adjustable with a screw just as it is in the case of a carburettor, and the EFI handles the rest of the variables like the AFR and remapping with changes in temperature and altitude to maintain stability of the engine's performance no matter what.

Cheers from the other side of the world.

Just sharing the knowledge I gathered here.

Edit: Remapping is again another different termilogy, but I'll leave that for another time.

Cheers!

For the info bro, R15 redlines at 10500RPM but 150R's Max. power is at 10500 RPM and the redline is still a 1000 RPM above at 11.5k RPM

Hydraulic Clutch for the R15

Has anyone replaced the stock clutch with a Hydraulic one on their v2?

Yes, basically, power is the capacity to build torque.So, more powerful the vehicle, the more capacity it will have to build torque at higher revs, or through the revband.If a vehicle has just lots of torque with no power to back up, all the torque would lie very down the revband with a pathetic performance when the revs rise up.So, say in an R6, the kick post 10k RPM is basically torque getting expressed due to the blessing of power..
This is what I think.PLease correct me if I am wrong!

Fuel Lid Problem

hi Frens,

I have recently got my R15 Fiery Red after reading your helpful reviews... here is one request to you members.

The fuel lid of my bike is not opening up, its kind of very tight...
And this is happening from Day 1, today i tried putting up some lubricant oil(engine oil) and then it was opened up that too after lots of pressure, hit and try fight.

Tell me what can we do.. ?
My bike is yet to get its first service done.

And can we lower the rear brake lever by few cms. ? Has any one of you tried doing it...
its kind of pain in ankle with high set up angle,

Regarding, fuel lid issue, I have seen in service centres some complaining the same.
So during first service, hope it would be rectified.
Regarding rear brake angle, one solution is to keep your foot below the brake lever, and rise up when needed.( I used to follow this) but always have a finger on front brake.( I feel front brake is more than sufficient for R15, rear is just to support at times of hard braking)

Its actually a major issue. You'll have to talk to the manager straight. Apparently the lock is faulty. Happened with my friend's LE. They'll change the lock/the whole tank - I'm not sure but they'll change it for free.
