MOTOREX KTM racing 20w60

First time i m using this oil, i had it in my bike for a few days now, gear box is really softer than before
but i m not sure that this rate (20w60) is ok for SDs. This oil developed by KTM espesially for racing
and my dealer insists that its the best oil for KTMs on the market... but i m still not completely
convinced that it really fits V-Twins...any comments?

Do you race your SD?

Basically I had never used Motorex on my SD and I tend to avoid them on my RC8.
I prefer Castrol over Motorex.
Even with Motorex 10W-60 on the RC8, it burns alot of oil...
Using Castrol (Power1 Racing 10W-50) oil consumption is by far less

where you from? climate will make some differance as to oil used. I have used 15/50 in mine. no problems, but that was over summer months and a track day. I am not great with oils but isn't the 20 the cold temp and 60 being the max temp. so you wouldn't want to use 20/60 in a cold or mild climate as it will be too thick on startup.

I had the same trouble with the Motorex burning off, as well. When I took her in for servicing that's what they refilled her with...

I run Motul 300V 10W40, and It doesn't burn off hardly at all. And it smells bitchin.

Putoline 10W 50 or 60 in mine. She burns a bit of oil but she makes awesome power so I'm not complaining.

Not saying it doesnt burn off at all; just nowhere near as much as the Motorex...

As for the smell, well, Motul just has a unique smell to it. If you've run it in your bike, you'd know.

Many think that the "W" means "winter".
From SAE J300 p.2:
"Two series of viscosity grades are defined in Table (1): (a) those containing the letter W and (b) those without. Single viscosity grade oils with the letter W are defined by maximum low temperature cranking and pumping viscosities and a minimum kinematic viscosity at 100C. Single grade oils without the letter W are based on a set of minimum and maximum kinematic viscosities at 100C and a minimum high shear rate viscosity at 150C. The shear rate will depend on the test method. Multi-grade grade oils are defined by both of these criteria....
The W is just a designation of one type of testing vs another.

But that's not important.
What you said is correct but a bit general, I just amended to yours, making it a bit more specific.

.....just a guess.......you work in the oil industry? (my middle name is Sherlock )

......So although w does not stand for winter...its denotes a winter rating for oil?

Well Sherlock that is something you will to find out by yourself!
No clues to help you!

W means what I wrote above, it has nothing to do with winter and there is no point of discussing about it...it was just a comment.
Though if you live in a cold climate (or its winter), you need thinner oil for startup (meaning the first number). Although it would be ideal to use the thinnest oil you can get for startup regarding of your climate. But that is not quite feasible. Because 90% of engine wear happens when you start your bike from cold.

When KTM tells you that the recommended oil viscosity is eg. 10W-50 means that when the engine is operational (meaning at operational temperature) the right oil has to have a certain thickness. The 50 grade oil at operational temperature (which is around 100 celsius for oil, not for water) has the thickness needed for your engine.

Now lets say that this oil at 100 celsius was a 10cSt kinematic viscosity.
When cold the (10W) oil will be much more than that, could be five maybe ten times more than that (depends on the type of oil).
So you see that there is no thin oil for startup, every oil is thick for startup...

Although, prefer fylly synthetic oils as they are better in cold start.

And something else: We say that oil gets thinner as the temperature rises. Well a good way of thinking is the opposite.
That the oil gets thicker as it cools down. Thats the real problem for our engines.

......er ...you may want to explain this to Silkolene...it seems they dont know what w stands for either........see cut and paste from site below...now where's me pipe Waston

Q) Please can you explain the grading system? What is meant by the weight of an oil? What does 10W/40 mean for example?

(A) Weight means viscosity, or resistance to flow. Water and paraffin flow very easily, so they are low or light viscosity. Golden syrup or 140 gear oil do not come out of the can so easily, so they are high or heavy viscosity. Especially with oils, temperature is very, very important. An oil which looks ‘heavy’ at 20ºC will be very ‘light’ at 100ºC. People sometimes say, ‘I drained the oil when the engine was hot and it ran out like water…’ so I say, ‘Good! It’s supposed to be like that!’ The American Society of Automotive Engineers (SAE) ratings cover cold start viscosities and ‘up and running’ viscosities. There are two sets of standards, the ‘Winter’ (W) ratings, and the 100ºC standard ratings. (‘W’ does not, repeat not, mean ‘weight’!) So a 10W/40 oil has to pass a 10W cold viscosity test at -25ºC, and a SAE 40 test at 100ºC. In an oil lab there will be a refrigerated viscosity measuring device for the ‘W’ tests and another at 100ºC for the standard SAE tests. There are 6 ‘W’ ratings from the difficult 0W at -35ºC to the dead easy to pass 25W at -10ºC, occasionally used in India for example! The whole point of these Winter ratings is to assist cold starts, to get the oil circulating quickly, and to avoid power and fuel wasting drag as the engine warms up. Once it is warmed up, the 100ºC ratings count. There are 5 of these, 20, 30, 40, 50, and 60.

Ok, sikolene says otherwise, why is it so important for what the "W" stands for?
I quoted SAE and you quoted Sikolene... ok sherlock
Now that you have "proven" that "W" stands for winter, do you feel better?
Is this the point?

...so (w) is for winter

and (b) is for Bul*"@*"t

Gonna perform my first oil change on my 08 and was looking for what I should run. I do not know what the previous owner was running as I bought it from a third party and they did not have any information on oil used. The bike has close to 6000 miles. I ended picking up some Castrol 5w/50, as I could not find the recommended 10w/50. I've put close to 700 miles and 1 track day and have burnt some oil. The oil level dropped from max on the tube to just below the minimum mark. Not sure how much that equates to. Hopefully this oil reduces oil consumption. Average temperature in my area is about 85F. Don't know if should have went with the 15w/50. What you think

Every body agreed .....except the 'W' part

As long as its motorcycle rated (motorcycle oil is designed to withstand shearing forces of the gearbox......)

.....As they say......'You pay your money..........you make the choice.'


....but it could be a VERY expensive way of finding out
