In the GRS 600, I have to say that from the 7100 to the 300v, it differs greatly. The changes are much smoother at low speeds; I mean, at high RPMs, it's pure pleasure how sweetly the gears shift. I highly recommend it.

Usage on Yamaha R1 5PW. 5 changes so far no complaints. Change every 5000km approximately after 5 you might feel that the gearbox doesn't change as well, but after all, it's not oil for 15,000km.

It is considered a very good synthetic lubricant, although I have not yet tried it on my motorcycle. Be careful to make sure it is genuine, genuine ones have a greenish color! If you get oil with a transparent color like most lubricants, put it on the chain for lubrication, not in the engine!

I tried them on a Ducati Multistrada 1200S DVT. After the change, I took a ride to test them and when I shifted into second gear, I almost cried for all the time I wasted with other oils. Unbelievable smoothness and the clutch works like a charm. I bought them for 18 euros per kilo. I highly recommend them as oils. Superior by far compared to Shell Advance full synthetic and Elf full synthetic. If it makes such a difference in Ducati, which are also "strange" motorcycles, it will work wonders on motorcycles that are more "friendly" like Honda, Suzuki, etc.

The best oil I have tried in the last 3 years.
I have put it in my Crypton X 62mm UMA and it really does an amazing job.
I recommend it to everyone!

First time trying Motul. I used to use Castrol. They didn't disappoint me. Since I switched to Motul's full synthetic product, I feel the engine is more "quiet," especially at high temperatures, smoother RPM transitions across the entire range, and quicker response to sudden accelerations. Fuel consumption has also slightly decreased during normal driving, both in and out of the city. Needless to say, I will continue to use it despite its liter price. (The tests and results refer to Suzuki Burgman 200.)
