Re: KTM 200 Duke

Hi everyone,


I am new to this forum & hv recently bought Duke 200. I have done some 170 odd km on this bike and love every bit of it. But I just have few doubts in my mind:


1) Whats the ideal rpm level to shift up the gears on this KTM? Currently I am trying to shift between 4-5k ( Dealer has set Rev limit to 5k till first service)


2) the bike feels underpowered below 4k rpm? Is it normal or am I not pushing the bike hard enough?
eg - When I try to take the bike to 4k rpm on gear 1 & 2, it takes a hell lot of time & the engine just screams so hard as if I am overburdening it. Only at 4k engine sound changes & you feel there is still a lot of power ? Am I riding it in the wrong fashion because in this way it takes me quite a bit of time to speed up to even 50-60 kmph ? Shall I shift 1-2 & 2-3 very quickly even in lower rpm range ?


Thanks in advance. Need some serious guidance.

Re: Duke 200 Engine Oil Grade?

Wrong.

The number after W (50 in this case) is the SAE viscosity rating of the oil.
The number before W (15 in this case) is the lowest temperature upto which the oil can maintain it's viscocity rating without getting thicker/freezing.

So, oils with ratings : 0W50, 10W50, 15W50, 20W50, will all have exactly the same viscosity at engine operating temperature (ballpark 100-120 degrees C), which corrosponds to the "50" number.

A 20W50 oil will get thicker at 0 deg C, so your engine will not get enough lubrication until the running engine heats the oil up (to 20 degree C) after a cold start... hence making it susceptible to wear.

So, obviously, 0W50 oils would be more expensive than 20W50 as they can perform in a wider "cold" temperature range.

As long as you are not living in some place where it snows... a 20W50 oil should do just fine (which is likely why it's 20W for india and 15W for europe, most of which sees snow)

Read the first line I said.

You said 50 is hot temperature. It is not.

50 is the SAE viscosity grade. Same as the oils that don't come with W ratings (which are rated as SAE 30, SAE 40, SAE 50 etc)

Re: Duke 200 Engine Oil Grade?

So you took it as 50degree hot ??? :O

Re: Duke 200 Engine Oil Grade?

How else was I supposed to interpret it? :\

Re: Duke 200 Engine Oil Grade?

Leme correct you. SAE 30 and various number is called as Monograde oil. Whereas, 10W40 and others is termed as Multigrade oil.

Google SAE J300, you will have your answers. Against 10 or other numbers there is a viscosity, the oil is suppose to match the said viscosity. Against 40 or other numbers there is a particular viscosity and has to match that. After matching the required viscosities, a company can claim the viscometrics for any oil.

A 10W40 oil works better in winter conditions as compared to a 20W40 oil. Vice versa for summer conditions.

In a laymans language, this is how it is normally interpreted "number before W indicates winter temperature, number after W indicates summer temperature".

Check out the Engine Oils forum. That will give you a better view about oils.

Cheerz!!

Re: Duke 200 Engine Oil Grade?

I was trying to convey the same thing i you said in the first part of your post and then you went ahead and said the opposite in the 2nd part. :\
Like you correctly pointed out... 10,20,30 etc are SAE viscosity grades, corrosponding to a pre-defined viscosity metric. This grading is done at typical engine operating temperatures because that is the single most important consideration for an engine oil. No matter what temperature you start at, you will always end up within the same ballpark temperature range, when the engine is running. The number before the W is an additional grading done in cold conditions, making it "multi-grade", as you pointed out.

Link : Motor Oil Viscosity Grades Explained in Layman's Terms

And I re-assert my points :

1. The number after the W has NOTHING to do with temperature (it is only the viscosity grade, measured at typical engine operating temperatures). So, no, in lay-man or any-man's terms, the number after W is not the summer temperature.

2. As opposed to your opinion, 20W40 will NOT perform better or worse than 0W40 in summers. That's not how it works. Both oils will have a viscosity grade of 40 at typical engine operating temperature and will be not be better or worse than each other. In winters however, as we both agree, 0W40 will perform better.

Re: Duke 200 Engine Oil Grade?

Bro, a 0W40 oil performs the same just like 20W40? you are wrong.

There is lot of difference in '0' and '20'. Try using a 10W30 and 20W40 oil in two different bikes, no matter what the season is. After certain Kms, get the parts checked. A 10W30 oil is thinner as compared to 20W40 oil. The numbers play an important role. They are not just any numbers.

Its better to discuss this in Engine Oil forum and not here.

Cheerz!!

Re: Duke 200 Engine Oil Grade?

I didn't compare 10W30 and 20W40 at all. Notice that i didn't change the number after W. That's the viscosity measured at typical engine temperatures.

I compared 0W40 and 20W40 and they will indeed perform the same, because the viscosity is the same (SAE 40) when the engine is running and warmed up.

With that i think we can stop the oil discussion and get back to topic.

What KTM India says about Duke 200 Engine Oil...


"Wishing you season’s greetings.
Thank you for writing to us with your query.

The Owner’s manual which got downloaded is for the 200 Duke – Europe version.
200 Duke in India would need different oil owing to difference in operating ambient temperatures.
Also the brand Motorex is not easily available in India.

Hence oil recommended in Owner’s manual for usage in India is,

Bajaj DTSI 10,000 20W/50 or Motul 7100 20W/50.FULLY Synthetic.
Both these oil meet specification required by 200 Duke engine.

We must say that we are impressed with your care regarding choice of oil.

Welcome to the KTM’s Orange world. Wish you miles of happy ride in anticipation.

With warm regards
Team KTM – India."

Hello People,
Has Anybody Installed Or Has Taken TR Of The KIIRU'S ECU for the Ktm Duke?

Re: new Ride!

Dukers,
Can you please explain me about Gear ratios? I went through a couple of websites to understand, but I am not clear on that. And also I have seen like Primary & Secondary Gear ratios (Even more confusing now).
According to my understanding, if the D200's 14:42 Gear ratio is implemented on D390 which has 14:45, then it will go even faster. What you say?
Share some knowledge and get me educated.
