My requirements :

1 . Little more power 4-5 bhp increase.

2 . All spares should be reasonably priced and available all the time at Yamaha service (cables , clutch plates ,disc pads , chain sprockets etc etc )

3. If psbl to execute the above 2 requirements asap..

Thats it..

Hmm people are complaining here about horn/battery ok here is what i have to say..
-->if you don't like the horn please go ahead and change it and make sure you dont put a double horn or some fancy horn.. [the horn which should be put on the bikes are 72db horns if you go by the rules]

-->And about the battery, you need to appreciate Yamaha for using a 3.5A battery which runs a ECU/Head lights(35w*2) without any problem and if you are a tourer or of you wanna show off please go ahead and install HID.. ok dont start over again.. [FYI: navnish have installed HID which runs on the stock battery without any problem, you need to search for HID which suits the battery, many are available in the market]

-->Now comes the power factor.. i cant remember any 4 stroke 150 CC engine which punches out 17PS and yes the low end torque is less but its the character of the bike.. its a high reviving engine and we have to live with it, its after all just 150 CC engine

--> Performance ECU is are always welcome but how many of you are ready to install it and loose on the mileage front i don't see many

--> Yes accessories should be made bit cheaper but cant help its Yamaha

--> About the tier its 100/80 same as found on the RTR/P150 but the rim size is smaller so the tire looks smaller.. I think Yamaha would have worked lot on this by now..

True Mithun! I do not want an air-horn or something, but atleast something as loud as an Activa or Platina. I remember Santa talking about tuning the horn, but never tried it as yet.

Agree to this, but the issue is that the battery discharges quite fast with hi-beam, radiator fan and horn. I do not think this frequent discharge and recharge is good for the battery either.

Again very true! But another 30cc or something never hurt anytime. Did it?

I would. Although I do not know how much of an improvement just an ECU change can warrant in the power figures etc considering that Joel has already revealed the physical limits of the engine.

After seeing the tire at the championship I would not dare talk about it!!

@apar: I think you were not there when Sanjay told about the horn during the last championship, he said "People complain about the horn when they can pay 1L for the bike then can't they upgrade the horn if they want louder horn, the thing is we are not supposed to put horn with db is more then 72db.. "

about the HID.. navnish we need your input here you are using it for some time now.. i dont think it caused any problem on his bike thats what the bugg told me

About ECU i will also sure go for it and about that 30CC no one would complain will sure upgrade if the launch one in futuer

Was there... He also mentioned what kind of horn to put. But the problem is the battery discharge. I do not want to end up with a bike with a dead battery and a non-working ECU or something. I know am exaggerating, but yeah I get scared quite easy!

1. A couple of BHP more.
2. Better service and availability of spares.
3. Under seat exhaust
4. Split seats

The R15 is a great bike.... but just like with any good product it too has some niggles. ahem.... I just hope there's someone at Yamaha who'd really listen to their customers!... unlike the great Honda & Suzuki. Here's a few from my side:

Minimum stuff:
1) Better Battery. Need more amperage out of this battery to support more powerful electricals.
2) More intense lighting... the headlight spread is very good but intensity sucks for the speeds we do on this bike... even in city riding, the bean needs to be more intense.
3) little bigger storage compartment under the seat
4) gear & rear brake levers need to be lowered... this really sucks big time... for such a sporty riding position these are set up like a commuter position
5) the tyre throws a lot of mud towards the suspension, chain & sprocket and even the rear disk setup. What ever protection is given already is very inadequate for our conditions
6) The bike should do with a little better pulling in lower gears... I mean when with a pillion in the city, I should be able to pull the bike off a pot hole or speed breaker in at least the 2nd gear instead of coming to the first!
7) Did I forget the horn??? at least, this is something I can change easily from the market and that doesn't cost me more than Rs 150.

for touring
1) a bigger bubble
2) little higher clip-on's
3) A clock... that is waterproof and can be attached somewhere in the fairing without the fear of some idiot flicking it off or something that we can fasten and take out as and when we need.

For some reason i find the horn is good and even louder when the surrounding is quite

Inputs well i was surprised to see the HID work so well on the R15. Thanks to siddharth ( Sidhusmart) he got a pair of this HID.
4300K Single Beam HID Regular Ballast Kit [HID43KSB] - $99.99 : Got HID Xenon? We have 4300K 6000K 8000K 10000K 12000K 15000K 30000K Kits and replacement bulbs.

And its working perfectly..Am using the 35w bulb + HID both on the high beam and no issues till now. The battery was fully charged even after 4 + hrs of night riding... (Checked the battery as soon as i came back from that 4hr + hectic ride.)

Regarding the horn sounding low with the both the headlights ON. yeah i had this problem but it was nothing to do with the battery the horn needed to be tuned .

now they are letting us change the horn but in the first two months of ownership the SC ppl repeatedly stressed that any changes made to the electrical system will void the 2 year warranty..which is the reason most had complained repeatedly to the YMIL people.

oh and there will be people who will crib if the 180cc will be launched..namely me!!!

More 100cc
split seats
under seat exhaust.
a bit height
plz plz plz - more fat tyres like fz16.

When i first saw the R15s engine on the net i was pretty disappointed...My guess was correct,it ended up a long stroked engine which is good for touring but not racing....They were clever and used a 4 valve setup..Ok accepted it all depends on the way u make your engine breathe long stroke or short stroke but a short stroke would have been MUCH better...Maybe they wanted the best of both the worlds...Just my personal opinion....

Ok, heres my take

Horn - Seems like a big issue here now eh. Well I personally wont mind that and the reason why a lower rating horn has been provided is to lower power consumption. All here know the battery is a 3.5A unit and has to power everything else. A bigger horn will weaken the link.
Also its not even recommended to use a louder/higher output horn as it will harm the overall electrical power consumption and in a way even disrupting the ECU power. Loading the electricals with a larger bulb/horn/buzzer etc etc is a strict no no.

Battery - Well the 3.5A battery does a very good job of taking care of all the needs. Its true that it cant support a higher wattage bulb etc etc, but has anyone here thought why Yamaha has done this? Any 150cc Indian bike in the market today runs a 5-9AH battery, so why did Yamaha do this?
Reducing the size of the battery will give the following benefits
*reduced charging power
*lesser load on electricals
*Can run a lighter magneto and hence improving performance. Just compare the magneto in the R15 and all other bikes. There is very less magnetic drag. Hence engine power is hardly robbed.
yamaha has done a lot of other clever things on this bike to make it peppy and refined while keeping such a low displacement.

Headlights - I'd suggest to look for a 35W HID kit. Works well.

Tyre size - I find these the most perfect set of wheels among any Indian bike. It looks thin agreed but surprises with a free grin on your face. They are super.

Engine Performance - Low end torque is very poor agreed, but the R15 was to give the character of its bigger cousins..so frankly it cant behave like a pulsar/unicorn. if thats the need of the hour, the engine will have to be tweeked.
Frankly there is no fun in riding such a bike anywhere below 5000rpm. People here have been exploited by the splendors and other commuters, that an SBK character is not preferred. if you were riding a piped 2-stroke, u'll find the R15 to be 100 times better.

This is no feedback to yamaha and I have nothing to do with them. Maybe we can have our own array of aftermarket bits to make this bike more complete.
So if we can look into all that one needs, things can be planned accordingly. India seriously lacks proper after market kits/parts/accessories/go fast bits and that too bike specific.

Joel
I have noticed that the R15's stock horn is 2Amps whereas many other bikes have a much lower rated horn but sound louder. Also, the R15's stock horn is very sharp.. can be heard for long but is not strong enough to make the listener think that you are just next to them!!!

any ways, a good thread for every owner to pipe out some frustration... LOL

Joel can you help out on the power side...

The other day was talking to akhil regarding the cat con. is it possible to remove it from the R15s exhaust ?? any fundas on this one... need the bike to sound a bit meaner ...

any other mods what can be done for increasing the power just a lit bit....
