FWIW, the dealer in Bristol (UK), where I bought my Cafe made a big point that if I was going to change oil/add oil at any time to use "semi-synthetic," but never full synthetic.  He did not recommend a brand so I didn't get the impression he was pushing Kawasaki-branded oil.

As I said...FWIW! 

 Since I don't have a garage/works space here to do any work myself, for the first time a bike of mine will end up at the dealer for all service so the bike will get whatever oil they put in it.  :027:

Then he’s an idiot.  And if I were paying someone to change my oil they’d damn well put in whatever oil I’m paying for.

Kawasaki doesn’t recommend semi synth and frankly, semi synth is half as good as it could be (full synthetic).

Don’t be so sure. I’ve read this elsewhere, but the article linked below is a good source. “Semi” doesn’t necessarily mean “half” when it comes to oil. I think that’s why some are just called “blend,” to avoid misleading advertising.

“Lastly, there are no industry specifications or regulations that define a minimum amount of synthetic base oil that must be present for an oil to be classified as a synthetic blend or semi-synthetic.”  https://blog.amsoil.com/the-pros-and-cons-of-semi-synthetic-oils-and-synthetic-blends/

I have a simplistic way of looking at it -- if I buy Motul full synthetic oil I will assume it is more synthetic than Motul semi synthetic.

After trying Motul 7100 on one bike, and then putting it on the other 2, I’m a believer. Never did I think I would say this... I Always used good brand name synthetics, but they are pretty much the same, and had not found a difference in all my vehicles between them; thus, alternating between brand name synthetics depending which one was on sale. But on all 3 of my bikes, I’m sure it is not a coincidence the temp gauge dropped at least 1 bar, and more, and shifting is even better. Especially on the Z, that 1st oil change transformed the bike, and the shifting.  Motul has me now. To the point I will be trying it soon for the 1st time on a car, on my new Ridgeline.

Been using Mobile 1 full synthetic for 45 years in everything I own.  Including my Cafe. Never once let me down. Get it on sale at Walmart for 25$ for 5 quartz.

My last two cars had Mobil 1 from the factory and I’m quite satisfied.  I’ve used Amsoil on my bikes for years and I’m also quite satisfied,  extended change intervals, cooler running and smoother shifting.

Just changed from Motul 5100 (synth blend) to 7100 (full synth), I hope the improvement in shifting comes early. Probably take it out tomorrow morning for a little ride.

I found exactly the same on my ktm.transformation of gear change from notchy to silk! Keep thinking car too! And it'll always be in all my bikes!

I'm using Motul 7100 full synthetic.

Cruising down the highway at 60 to 70 mph in 23 C (73 F) weather temp gauge showed only 2 bars.

Other factors I'm sure come into play. Akrapovic header & 16th sprocket I suppose.

If you really want to treat the bike, use Motul 300V.  Comes out looking perfect after 4 laps of the TT, and engine builders love it. Bit salty at £50 for 4L, though.
