Here're some questions for you though
- Was the road flat?
- What was the weight of the rider?
- What was the tail wind's direction?
Most importantly...was it really stock

Though I don't underestimate, my experience has taught that, CBR is not capable of doing not more than 135/137 under any circumstance which is what I call a true speed.

I would like to share my experience with you. I went for an early morning ride and I touched 140s many time and did a top speed of 148. In the past I've done 154 also. Btw I weigh 85kgs, full stock and I shift to 6th at 145+. I personally think that Cbr can hit 160.

Note: All the speeds mentioned here are speedo indicated.

See, I do not deny your points; I myself have done 155 on the last BFast ride from Pondi to Chennai via Tindivanam; there're some stretches where you can certainly do 155; on the same road, while you keep the same throttle position, your speeds gets down to 139. Now remember, there's no one on road, nothing to brake, fully crouched, no turns but still the bike drops to 139. Why does this happen? This is exactly what I'm trying to convey.

There's a stretch in Chennai bye-pass that I do 5 times a week up & down. You can easily go upto 150 on the forward leg, but find it hard to cross 144 on the return leg. I've done this stretch say like over 150+ times (8 months) on all type of weather & all windy conditions; just that I had a backpack & myself not more than 100 Kg. This is why I said, ON ANY CONDITION, 135/137 is possible (that includes the upstream also)

just search YouTube.there's a video of cbr doing 174 @ redline on some highway here.

I weigh 35 kilos more than the average rider to hit such speeds
The bike does sound stock and other questions could be answered when i get some answers from the owner himself on YT.
i can only manage 156-158 here before i run out of roads or have to bank towards a curve.
However top speed isnt my thing anymore... it is the ability to cruise at 120-130 on the highway that matters and she does it without complaining.

Btw for you regular riders or tourers, how often do you check the engine oil level and have the need to topup?
I know it varies per region/temperature but still.

Acc to the vid. 0-100 was reached in less than or equal to 8 seconds .

That is with a CO box

I don't believe things unless I test it thoroughly, all these YT & other things are something that I don't believe.

The point is, are you able to consistently do the same speeds on different roads under different circumstances?

+Million & counting!!! Also you notice the comfort of 7.5K RPM when you do that & its still relaxing; atleast to me upto 8K RPM it is relaxing. IMHO, the bike is designed to do 85mph all day.

I keep checking may be once a month or so

Edit - Let's not brag about the top speed guys; anyone who has ridden extensively will know the true potential of this bike & there's no doubt about it. Doing upto 135/137 on all circumstances (includes pillion, saddles, cross winds & upstream) is possible; any other favorable factors help the vehicle move faster. Period!!!

i have done 146 with pillion and around 154 solo

depends on the road condition.
Minute changes show huge deviation in the speeds. The tyres seem to be very sensitive to changes(as reported in my fb status this morning )

IMO concrete roads make the bike feel very lazy and maybe the weight of the bike acts against it when there is too much rolling resistance compared to tarmac roads.
Yesterday i was riding through the empty city stretches(Concrete) where the bike felt lazy to go beyond 135kmph... crossed an intersection onto NH 17 and revved all the way to 10.5k rpm in each gear and hit 155-156kmph easily.

Now i need to know is it me or is it really the switch from concrete to pure highway tarmac that causes this behaviour.

Exactly my point!!! there's no point everyone here to keep arguing that the bike can exceed 150, 170 & I kept clearly saying "under all circumstances" not like the mileage testing criteria!!!

I quite understand it is possible

See my previous posts; its all the factors put together makes the bike go faster; otherwise the bike is capable of doing not more than 135 under any circumstances.

Top Speed


I personally have done 159 solo and 156 with a light pillion (girl) on NICE road.I weigh 75Kgs.

I have done 139 with a pillion rider (boy) on bangalore chennai highway.
If i am doing 145 crouching and i get upright there is generally a drop of 10KMPH. I guess thats the point that aargee is trying to make that why there is lack of torque at the top end of the powerband.

I do want to cross 160 but the current situation of my bike does not allow me to (not very stable above 110-120, probably coneset issue).
Engine wise she still can but the handling is not that great these days.
After they changed the swing arm replacement part sent by Honda, this all started. My rear shock seems too soft and when i am with pillion, i see the boat ride effect. I tried to change the rear shock setting to 4 or 3 but the tools provided are not good enough (or i am not doing it the right way).
Any idea what might be the reason for reduced stability of my bike.
My handle makes a khad noise when i break hard so i guess it might be a coneset issue. My bike got serviced 2 weeks back and i told them that the handle does not seem right, they said its fine. I saw the checklist posted by aargee last night and realized they have not done any of that.
I was not such a fan of going to other ASC but Haiku is not leaving me with many choices.

Any help in restoring the rock solid handling of my bike would be appreciated.

Hey guys i have done approx 2200kms in two months. i have driven it on highways with pillion and without pillion but every time it did not touch more than 135kms. every time throttle was on max position it did not take time to reach 135kms.

there was strong wind force so that could be the reason but after reading here feeling like MC42 engine is very much underpowered

...

uploading pics of slight modification in headlight (angel eye and SMD(white) parking lights)

How much do you expect a MC42 to do? And pls define underpower for a single cylinder 250cc it matches upto 90% of the speed what a twin cylinder can do.

Are you using 10W30 or 20W40 grade engine oil? If you use 20W40, then you're perfectly fine for those speeds.

The headlamps goes perfect for HRC scheme. Blue looks cool though.

@aargee
i meant as compared to MC41 which is available in US and other countries.i am not comparing it with twin cylinder.

I am using 10w30 Honda throttle(the one which honda guys provide during service) I guess for 20W40 we have to buy from outside.

THANKS

As a matter of fact MC41 & MC42 are identical; the power difference comes due to ECU

Shift every gear nearing redline; 5th gear the bike should do 142; if all fails, time to try a different road.
