Versys 650 2016. Known for the more "stiff" gearbox, and with the first few km I saw a smoother transmission, a smoother engine operation, and what really impressed me was that the engine was more responsive from low revs without requiring a downshift like before. Now we have to see whether it will hold up over the kilometers. Max 4000 km oil change.

installed on a 2005 suzuki sv 650 with 80,000km. clutch is buttery smooth, first gear no longer knocks like it did with previous oils, I don't search for neutral at traffic lights, and oil temperature while riding is 50-60 max. you pay a bit more but they are worth the money.

I put it on a KAWASAKI VERSYS 650 2012 model a few days ago, which is known for its hard gearbox. From the first ride I noticed a huge difference. It became much smoother when shifting, especially in first gear where it used to sound like a knock. As for the oil's durability over time and kilometers, that will show in the long run.

No special introductions are needed for this particular brand of oil. If you're here, you know why you're buying it.

On a Vstrom 650 with 70,000km. Compared to Suzuki's semi-synthetic oils, transformation. It doesn't shift gears. I'm talking about normal driving, at the traffic light you play with the lever to find neutral. If, for example, you forget and stop in 4th gear, forget it.

I read the reviews and decided to try it. It was installed on a VF 185 moped and indeed the gears shift very smoothly and the engine sound seemed different to me. Its price is not prohibitive for a change at 3000km.

Excellent product, quite a bit more expensive but it's worth the money. At 1000KM the gearbox is much smoother, nothing like anything else I had tried on the Tracer 7

Good oil, I tried it on a Tracer 2025 and the gearbox is a bit smoother

Gsxr 600 previous oil shell advance 15w50 I use liqui moly cleaner, do the change and put lidl's 15w40 at 3 euros per liter to remove the residues, do about 100 km, change it and put the amsoil 20w50 with a new filter. Good oil, nothing special though, no vibrations at high rpm, gearbox same as shell and lidl's, only with shell at over 10k rpm it wouldn't take the gear, resulting in the bike dropping to the previous gear. The only problem I've encountered so far is the temperatures: on exactly the same route, with exactly the same speeds and the same ambient temperature, shell worked at 79-80 degrees, lidl's at 81-82, amsoil works steadily at 83-84 degrees. For the 7.5 euros I got it on offer, 2 stars; for the 14 euros it costs now, not even close

Excellent for fz6 s2 fazer, aggressive and torquey (R6), outperforms Katana and maintains very good temperatures under pressure on Egnatia and in traffic jams. As for the gearbox, I wouldn't say no, it remains moderately hard

In Fazer 600 '2004, it is the best tested in 10W40. With Amsoil, I saw incredible gearbox performance, a bit more power at low RPMs, a quieter engine, and mainly easy revving. I change oil every 3,500 to 5,000 km. If they continue with this performance up to 3,500, I won't change brands again!! My ranking is 1) Amsoil 2) Torco full synth (I can't find it anymore) 3) Bel-Ray Exs. I had also tried Motul 7100 five years ago, and it didn't go well at all. I might have fallen for counterfeit products that were indeed circulating a few years ago.

sym citycom I come from Castrol and after 1500km it was burning them. I was trying to keep them until 2.5k which I eventually filled quite a lot. I put these in and I was relieved. Better engine performance, easier start. If anything comes up, I will return.

Perhaps the best synthetic oil on the market. I have been using it for years in a Kawasaki Z750 and in a Zontes 310M scooter for a year and a half. Very smooth operation in both and absolute protection for the engine. Find the comparative friction test on YouTube against other synthetic oils and you will understand what I mean.

A very good synthetic oil with good behavior in the transmission. You probably won't notice a difference compared to other good oils except after long-term use regarding the wear of your engine. I chose it because it is one of the cheapest fully synthetic oils (and not processed mineral oils that use the title of synthetic).

In the Kove Maverick, there was a significant difference in the gearbox and gear changes. It was quieter during gear shifts

I used the 20-50 fluidity in my v storm, believing that the gearbox would become even better with what I had read, in the end I see exactly the same gearbox and engine sound compared to the castrol I used before, but castrol costs half the price of amsoil. Good oil but probably not worth the extra money.

In SYM MAXSYM 400i ABS, all summer with daily riding outside the city, after 4000 km I have only good things to say! With external temperatures above 35 degrees, the engine never stalled and its sound was always quiet.

cbr 125r 2004 model, I use Castrol for the engine and gearbox, I use MOTUL 7100 for noise again and difficult shifts that sometimes I couldn't find neutral, I use bel Ray and it improved somewhat, I also use these and the revelation came, buttery smooth engine and gearbox, 3000 kilometers under pressure the bike didn't burn a drop even with temperatures of 40°+!!

Amazing oil. It was put in an FJR1300AS (automatic). The engine works perfectly, but the big shock came in the operation of the gearbox, especially during cold engine start. Highly recommended.

A 100% synthetic oil from a well-known American company. I have been using it for my last three oil changes, every 4000-5000km on a 300cc twin-cylinder motorcycle. I have nothing negative to report.

I got the Amsoil oil for my scooter. Before, I had the Castrol ones, the gold ones, but I wanted something better because I do a lot of kilometers. I noticed that it made it more responsive and slightly quieter compared to the Castrol ones.

I have been using it for ten years on my BMW 440i stage 3 740 hp with 10w60 and on my Kawasaki ZH2 with 10w40. The best oils out there, few have knowledge about these oils.

I bought it for a change on my Crypton X 57mm.
After a few kilometers, the engine revs nicely.
I will come back later after the oils have been used more
