yeah anna there were few rumors that this bike gonna get launched by end of this month or next.....still no sign nor talk

does anyone know the exact details abt the cc,bhp etc etc of zmr(changes compered with zma?)

are sprockets so effective compared to all dose mentioned above!!

never heard tha before.....are all the above stuff fitted to ur bike along with sprocklets give u that speed? ..or.. u tried all dose and had no result so changed to sprocklets?

Ravi anna.. i filled Motul 300V((15W50)) last month....will there be any probs in future? kindly reply

A sprocket is a profiled wheel with teeth that meshes with a chain, track or other perforated or indented material. It is distinguished from a gear in that sprockets are never meshed together directly, and from a pulley by not usually having a flange at each side.
Sprockets are used in bicycles, motorcycles, cars, tanks, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc.
In the case of bicycle chains, it is possible to modify the overall gear ratio of the chain drive by varying the diameter (and therefore, the tooth count) of the sprockets on each side of the chain. This is the basis of Derailleur gears. A 10-speed bicycle, by providing two different-sized driving sprockets and five different-sized driven sprockets, allows up to ten different gear ratios. The resulting lower gear ratios make the bike easier to pedal up hills while the higher gear ratios make the bike faster to pedal on flat roads. In a similar way, manually changing the sprockets on a motorcycle can change the characteristics of acceleration and top speed by modifying the final drive gear ratio.

Today while i was trying to accelerate hard on 1 st , 2 nd and 3 rd gears , i noticed that just before i complete the full throttle small knocking sound is coming from engine . Is it normal ? (My bike had completed 21 k )
I just want to know whether it is any problem or normal thing .
Other than the sound everything else fine . Having nice acceleration and giving good top end (touching 130 without any fuss) ..

hi! every single thing installed in the bike is very effective. but still i was greedy for more speed at lesser rpm's, coz in stock sprockets bike use to reach redline at 130. so does it make sense for zma goin at 130 that too after struggling very hard. then finally i did sprocketting and its the god father.

hi jithu! no dear, it should not make any kind of sound. go to hh authorised workshop and ask them to test ride. then see what they guys say.

Any idea what will be the problem? I told the HH service center guy about the problem when i gave it for servicing but he didnt rectified it (i think he dont know what is the problem ) . THe HH service guys will do only the things we asked them to do .. From my experience they wont spend too much time in spending the cause of our problem .If we tell them specifically what the problem
is (for example if i say gear is not smooth ) then only they will rectify it .. If i say i have a problem like this and i dont know the cause then they wont spend too much time in inspecting and the problem will be unsolved after the service most of the times .. i think this is why most of ZMa owners prefer individual mechanic over HH service center .Individual mechanic will give more care to your bike and ensure that the problem is solved but these HH guys wont spend too much time checking the problem even though they have all the tools and equipments

So if any one of you can identify what will be cause of problem , please share it with me so that next time i give for servicing i can tell those guys what to do ..

u say sprocketting gives u a top end of 160kmph!!...if so one wud nt hesitate to get it done.cn i know hw much did it cost u?

ravi anna and other experienced xbhpians throw their fews on this plz

Just increasing a tooth in front sprocket or dropping a few from rear sprocket,will decrease your top end.
unless you plan other mods,that bump engine power.

Folks,

I want to install a better bulb for my ZMA. Right now I have the Osram bulb, a simple halogen bulb. I searched the net and found 2 recommended ones:

1. Osram Nightbreaker
2. Philips (don't remember the full name)

I noticed that they are 55/60 watt bulbs (I guess). Any mods required in coiling? Or just by installing these bulbs i'll get better results?

Please advice.

For installing 55/60 watt bulb you need not fit anything extra.. It is a direct fit on your ZMa ..

1. Osram night breaker is 100 w i think .. i think you have to change the relay and coil for that.I think it is illegal also .

2. Philips have 55/60 W bulbs . The best one is Philips extreme power H4 bulbs . They are direct fit on the bike. Regarding light , yes it will give more light than stock bulb but if any vehicle is coming in opposite direction you will be blind but when there is no vehicle in opposite side it is more than sufficient
you can drive in any road with confidence.

But the philips extreme power is difficult to get . i dont know the availablity in your city . In chennai it is availabel in only one shop as far as i know .
(many shops never heard about this bike ) .

It will come only in pair .For 1 pair it iwll cost you 800 rs.

You can check the pictures below.

Osram Nightbreaker.
Philips Extremepower.

Both work excellent and are 55/60W. No need to do any extra fittings, just plug and play. Regarding the intensity of light, what Jitu said is correct.

OSRAM is illegal?
