Ok.....as u said Upgrade will ruin the flickability of the bike but for your kind information The Bike called R125 in UK market by yamaha has 130(r) and 100(f) section tyre and it is well engineered than R15 & feels big enough also the bike has 1355mm of wheelbase. Even the Ninja 250 has same tyre spec as mention above and 1400mm + wheelbase.

First of all, bigger wheelbase doesn't always mean extra stabilty. It's the "(longer swing-arm)+(shorter wheel base)" combination that gives stability and flickability to your bike. And as for R15's fishtailing rear, I've never experienced it..and yes, I do speed a LOT. Any bike tends to move from its straightline when you break with the bike leaned onto some side even slightly. But fishtailing? Sorry, this is no pulsar to have such soft suspension and chassis.

And about the R125, we don't understand on what basis you say R125 is better engineered than R15 when the whole world says the opposite. Just that a bike looks and feels big doesn't mean it's better engineered. The performance of a bike is what shows how well the bike is engineered, and the R15 beats R125 in all aspects of performance. And by the way, longer wheelbase will actually hamper the cornering ability too. So, think about it.

Guys any of you face problem with the r15's battery? Yest i got projectors & HID installed and suddenly after parking my bike at home, i tried starting it again and it wouldn't. Next day morning i had to push-start bike and go to the service center, just to find out that the battery was charged as required and that nothing was wrong with the battery.

console

[QUOTE=svjhonda;486366]@ Above- dude, no issues. Its the lean angle sensor which got triggered. After you right the bike, switch off and re-start the bike, it works fine. Nothing to worry about. Although these tiny nicks and knacks are mentioned in this thread. Many people have gone through the ownership and faced these issues. So best search, if you don't find relevant answers, only then post it as a question.

thanks brother....i faced another issue.today i rode my bike for 2-3kms,after which i stopped for some work>>>>after that i started my bike to head back home,so i turned the key and pressed the self start button but to my suprise the console went off and again started itself and this happened two times,so is this a serious problem with the console or is it related to my lean sensor which came into play yesterday....thanks

Probably there's some loose connection in your bike's ignition (like when you turn the key on and off). Rainwater may do this. Observe for a few days, and if it happens again, ask the svc to open up the ignition and check for loose contacts.

Otherwise there may be a fault with the speedo, although this seems unlikely. Just obverve for sometime...

Maybe the wiring isn't proper and there's heavy discharging while the HIDs are running.

As a suggestion, you can take the pilot lights off (that saves 10watts) and avoid using the HID in slow traffic. Also don't power on the HIDs immediately. Start bike bike, ride for a kilometer or so, and then switch on lights.

Monsoon Issue - Spark Plug Adaptor

With the rains lashing Mumbai for the last couple of months my bike developed a problem where it began showing acute symptoms of the engine "missing". Things got so bad that I had a tough time riding it to the SVC center which had to be in 1st gear and the bike continuously stopping the moment the throttle was released.
The SVC guy told me after a brief check that the spark plug adaptor had shorted. Which happens due to rain or moisture getting into it. The part cost me 75/- and was changed in 10 min. The bike was fine after that.
The SVC guy further added that this is a common problem with R15s as the adapter is slightly exposed to rain though at an angle. Fortunately the problem can be rectified cheaply! So if you find your bike stopping or missing during this season - the probabilities are high that it is a spark plug adaptor problem.

@akshay-- thanks for the important update/caution

**Rajesh Mudaliar** · 08-31-2010, 05:22 PM

Guys my front Brake Disk has some deep scoring on it so that my brake pads gets worn out soon... i just want to know that can i skim off the Disk with 0.3 r 0.5 mm so that those scoring will be faced off... ? and if i do that will the brake caliber get adjusted to the new thickness of the disk ? are should i replace the brake disk ?

The 150cc, One Lac question!

Guys, I'm close to 3000kms on my R15, and the only thing that keeps bugging me are the usual question, "Kitne ka?" followed by "Kitna CC" - followed by a totally zapped look

! Now I get too darn technical trying to explain the bike's low weight high performance mantra, but generally fail! Guess, this will be a bugbear for life!

ps: Was elated to read in an earlier post that the R15 could last upto 200k kms or more! Wonderful! I put down a lac on the bike purchase(replacing a 7yr old Pulsar 180), knowing that it would probably be my last bike, after which I would be putting down cash for a car, and that I would always need a bike around - Japanese quality should last a lifetime!).

Hope to pen down my R15 experience soon. Sheer joy!

Yesterday--

How much?
Me-- 70K only

FE should be in the region on 60kmpl?
Me--High 80's

Q--

Once he recovered, which company?
Me--head off to Yamaha, post which i downed my tinted visor, had a great laugh post gunning it.

I went to the SVC and spoke the manager, he seemed like a nice guys, suggested me to get the battery replaced under warranty, if that same problem occurred and told me to insist that i want the TATA green battery instead of the Minda because the TATA battery is of 1.1Amp where as the Minda is 0.9Amp.

Would it harm the bike in anyway getting a battery much higher then 1.1Amp?

If you mean grinding the disc surface so that it gets smooth once again, I'd recommend you don't do it, because if the thickness isn't even all around, you'll be in a hell lot more trouble than now. Also the process would be too tedious and expensive.

Simple, use this disc, till it reaches the minimum thickness (3.5mm, over a few different spots) and replace it. And henceforth maintain the disc brake, as in, clean the disc surface if its been ridden through dusty places. Especially during monsoons.

Lol. I'd once actually managed to convince some locals at Burdhawan that this was a 800cc 3.5 lac machine. They were asking me all sorts of questions like can it beat a running train and stuff...

Lol running train!! :P......maybe they should've used an R15 in burning train

**ezy_rider** · 08-31-2010, 09:23 PM

Parth.... We had discussed about i had an accident last week. I need to change the Outer panel with R15 decal, the inside panel with grill on it and the front headlight cowl. My bike is Yellow color. You have mentioned the Price of the parts. Need to clarify it one more time. So please

Even a haya busa or and R1's rear tire will give out if you grab the front brakes. To prevent the rear from skidding, you need to use the rear brake in tandem with the front. trust me it will add stability to the bike while hard braking.

buddy it is not a question of which bike is "well engineered than R15". It is not a bike big on performance. It struggles to reach even 125-130 kmphr in stock form. And If you were just into looks, which I deduced from your comment about r125 having bigger tires and bike feeling big enough, then sorry buddy, you should've bought a fazer

. Determining the length of wheelbase for a bike takes a lot of calculations, and I'm sure that Yamaha engineers gave R15 the best possible specs which is quite evident from it's handling.

And try to remember fatter tire may mean more rubber, but that does not make it any better than R15's stock thin tire. An r15 will runs it's best on the stock thin tires.

Ok Bro......How can you say that it struggle to reach 125-130 kmph even though bike is capable of 136 Kmph and mind well the R125 has 125cc engine and 15 PS of power while with additional 25cc of R15 has only 17 PS. In those sense the R125 is well engineered. Here question is why the bike has increment of only 2PS while the engine is so much capable to handle extra power also R15 is not the fastest Bike nor the quickest acceleration bike from competition and one more thing compare the R125 swing arm to rectangle section of R15 and you will noticed that how well engineered the R15 than the R125.

as far as rear is concern, I am not fool to use only front break. I used both the break. It is not the same time but alternatively. It is the technique in which you have to entered the corner with fast speed with some angle so that u can easily overtake the person front of you. This practice is strictly limited to Race track though i am not a track rider but an engineer.

Ok.....then tell me why the Kawasaki Ninja 250 beat the R15 on track while the it has the wheelbase of 1400mm (R15=1290mm) even longer than the Royal Enfield bikes......I am asking Why.....??
