Motorex Engine oil

At the end of the day, pretty much anything in spec will work fine.

That being said, I did a bunch of research for my V85 and determined that Motorex Cross-Power does the best in high demand applications. Air cooled engines can have a really wide temp range. That's what I use.

Pros: best in high demand

It works great, maybe a bit expensive. I've run used oil analysis and change it 3-4k miles based on aluminum wear. I don't see a reason to use something else.

Pros: works great
Cons: a bit expensive

I use Motorex semi-synthetic 4t in all of my KTM's over the years in a 15w50 weight. It has never been an issue. I have used Motul 5100 and 7100 in other bikes before, and I prefer the 7100 over the 5100. It feels like the bikes perform better when the temps rise and I'm really riding them hard.

Pros: bikes perform better

It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????‍♂️

Pros: works good
Cons: restricted power

Just came across this. Mine is a 2024 w 31 hours. I always used Motorex but I’m trying T6 this time. I use it in all my other off road bikes. In the 2t it’s just the clutch and trans. Also I’m changing it every 10 hrs

Honestly Motorex is a good oil, but it is extremely expensive for what you get. I specialize in performing Used Oil Analysis (Worked for Reliability departments for mining outfits) and it’s just a Ho Hum oil.

Pros: good oil
Cons: extremely expensive

In my Shiver 750, Motul or Motorex every 3,500 miles were required to keep neutral findable when you want it and hidden when you don’t. False or impossible-to-find neutrals were a sign that it was time for an oil change.

Pros: findable neutral
Cons: impossible-to-find neutrals
Mileage: 3500 km
