So I have just bought a 690 enduro r and wanna ask what oil is best for road use with green lanes ??
I use Motorex as I always do with my 450 excf but which is best for the 690 ??
10w50 or 10w60 fully synthetic??

help please

If the question is just 10W-50 or 10W-60, the first answer is to RTFM and select whatever is recommended for the ambient temperature the bike will operate in. The higher the temperature, the higher the second number should be. ie my 950 manual says 10W-40 for ambient temps below 0 C, and 10W-50 for above.
As for the difference between the two...well, all other things being equal, at working temperature the 10W-50 will flow faster than the 10W-60, but have a lower film strength.
Run a KTM on, say, 10W-40 on the basis that 'that's the right oil for motorbikes' (as sometimes happens when a non-KTM workshop services a KTM), and you get excessive oil consumption because the thinner oil gets past the rings faster.
The most important thing is that he oil you use has the correct JASO approvals and is wet-clutch compatible (MA2 standard) as some of the additives in 'car' oil will damage a wet clutch.
The 'W' in 10W-40 doesn't stand for 'weight' it stands for 'Winter' and indicates the resistance to cranking that it provides in a reference engine at Winter temperatures.
Back in the day before multigrade oils, you had to do seasonal oil changes...a 10 or 20 W for winter, and a 50 W for summer.

 

thanks
the user manual states 10w50 and 10w60 so guessing with the temp running as it is the 10w50 is a winner

 

The ktm dealer I bought from has obviously used the wrong recommendation of oil, it’s red and I know Motorex isn’t red.
Kinda don’t trust what grade they have put in either so I will replace with what KTM recommend.

 

Prob put in Motul 10w60, its red and dam good oil, its what ive run all 3 of the 1290's ive had, plus my 790, my 525 my 640 race bike also. There was an article where KTM had switched from recommending 10w50 to 10w60 in there racing 4strokes, they said engines lasted longer, especially the big end bearings.

 

Manual for the GasGas 700 (KTM 690 in red) says !0W-50.
Motul full synth...which a lot of us (me included) use in our bikes, is red.

 

0w50 ?? Is that a typo 😳

 

No, sorry it's 10W not !0W...but OW-20 oils exist in the car market.
Very low pumping and churning losses, hence good fuel economy! Insufficient film strength for our engines, though.

 

Thanks mate
Been using 10w50 Motorex power sync and always had no issues with that one .. it’s yellow in colour and is what the KTM manual states ..
the reason I wonder if it the wrong oil in the bike is coz when the engine gets hot it gets noisy..
the bike only has 500 miles on it so I doubt it’s wear and tear

 

Don't waste your money on fancy bottles.

10w60 4T Fully Synthetic Motorcycle Oil

 

Mines got less miles on than that...it's mechanically noisy when cold and at low rpm.
Providing your oillevel is OK it shouldn't be a problem. Presumably its under warranty anyway.

 

 

690's burn or use more oil than other bikes. If ridden hard my 690 used about 800 cc every 1000 kms (600 mls). It got better when I used Motul 300 V 15/60.

 

Believe it or not it’s a 2013 model.
Just never been used
Got 3 month warranty that’s all
