Motorex Power Synt 4T Engine Oil 5 5 6 6
KTMs really do love this stuff I recently had to grab a quart of "emergency oil" to get home, decent quality part synthetic 10/40, and my engine was loud and the gearbox shifted poorly. I had to order the Motorex 10/60 because I couldn't buy it locally. When I got it and the 8 or 9 filters required, and got a full quart on the catalytic converter draining the old oil, and finally got the oil changed, the transformation was very noticeable. My engine is quieter, the clutch and shifting work better, and it is just happier. I'll keep using this oil. November 9, 2015
Motorex Quality Great product in great packaging. Motorex never disappoints. September 29, 2014
Great Oil Been using this as the factory recommended oil in my KTM 990 since new. I go through it fast enough that I should just buy a 55 gallon drum! September 29, 2014
Oil change This is recommended for my KTM 690. Once I changed the oil, shifting seemed to function smoother. Zilla shipped very fast as well. September 15, 2014
Great Oil Motorex is recommended by KTM, so Motorex is what I use. It's more expensive that some competitors, but I buy in the 4 liter quantity so that brings the price down. June 17, 2013
Seems to be going well Every bike owner should save themselves a few bucks and change their own oil, very easy and this product seems to be doing well on my bike. June 17, 2013
