Improvement in the gearbox, improvement in temperature. I will probably put this in the Malaguti Specter 125cc.

I have done about 300 kilometers on crypton r 105 54 mm I do not have any additional only that it burns a little

In kaze r, I tried the Castrol 15w 50 instead of the Shell Advance 15w 50 I had before, I was banging my head against the wall, better to use cooking oil, I threw it away in 4 days, terrible in all aspects, I'm waiting for the Ipone to resurrect or maybe go back to Shell.

For ducks and generally for small motorcycles it will be just right. It is not suitable for big motorcycles. V-strom 650 is good up to 1,700 kilometers after the change, plus whatever you add and 200 ml..

BENELLI TRK 502. I use castrol on all my motorcycles. The whole operation and engine sound change. It becomes silent. The speeds are smooth.

The best thing I have put on the Astrea Honda moped. The gears go in smoothly, the engine works calmly.

In Vstrom 650 K8 with 105000km I tried them since I couldn't find the Bel-Ray that I always used, soft gearbox and quiet when it was cold, afterwards it was about the same as the Bel-Ray, increased fuel consumption about 1 liter and the last thing that bothered me was that at 4500km it needed a 500ml oil refill, same driving style, same routes, with Bel-Ray I didn't have this since the engine never burned oil or if it did, it was very little and I couldn't see it on the indicator!

From the moment I put it in the Honda astrea grand 110i gearbox, fuel economy and engine sound changed for the better... I reserve judgment on its durability after 1000-1500 kilometers and will write a new evaluation... 10/08/2022 for the price of a good oil without special requirements since after 700-800 kilometers the gearbox had become harder and rougher in operation as soon as the engine reached temperature... I stopped it and put the same brand 20/50

120,000 km on a Modenas Kristar 125. I used it exclusively for all the kilometers and the time for reconstruction came due to a worn secondary axle of the gearbox (external wear does not affect the oil anywhere). Well, the image of the engine is impeccable. Gears, gearbox, crankshaft bearings, connecting rod, and overall engine image are impeccable. If I didn't have to change this axle, which you have to dismantle the engine to change easily, it could have easily done another 120,000 km with this oil, maybe even more, but because I opened the engine and because I work in delivery, I had to do a complete reconstruction. However, my choice for lubricant remains here.

It was purchased as a very good oil for the scooter! However, it doesn't perform well! Especially for summer! It burns very easily, resulting in the engine running without oil very quickly! Never again! From now on, ONLY... Motul or Liqui Molly!

I do not encounter any issues either in disc braking or in tightening the speeds.
Also, the gear changes seem correct to me, although I change them in fewer kilometers than necessary...

I have been using it on my Crypton X 135 scooter for 4 years now, for every 3,000 kilometers. Simply flawless.

An affordable oil, which is of good quality. I use it to top up the oil in my scooter when it runs out, and I am completely satisfied.

Very good at high speeds, the engine runs smoothly after 2000 kilometers, but it consumes a little oil
