300V Factory Line Road Racing 10W40 4T Synthetic Racing Motor Oil with ESTER Core® Technology for Maximum Power and Protection 4L

I’ve been using Motul in my motorcycles for ages without a single oil glitch, keeping everything running smoothly. It quiets engine noise noticeably while boosting overall performance, which is rare in top-tier oils. No odd smells during use or changes, and it even helps with better fuel efficiency on long rides. The durability is impressive, extending engine life reliably. Quality-wise, it’s premium stuff—always opt for the full synthetic as recommended by manufacturers. The bottle’s design is practical, with side graduations for easy measuring and clean pouring. Though pricier, it’s totally worth it for the superior results 🤙

Works great for my R6. Has a pretty interesting smell.

I love this oil, been using it for all my street bikes. It’s high quality and it’s the cheapest spot you can get it. They charge you $100 at any cycle gear for this same oil. I highly recommend this oil!

The best oil you can buy for super bikes.

Quite simple best motorcycle oil you can buy ... keeps temps right down on my modified honda grom

I didn’t expect this. I’ve always been an Amsoil fan. I use Amsoil in everything. So when it was time to do the first service on my bike I used a new Kawasaki filter and some Amsoil for my bike. It honestly didn’t seem any different from whatever the OEM oil was. Nothing noticeable was different/better in any way. So after another couple hundred miles I got some of this stuff. I was going to wait until next spring to change it but I decided to just do it now. It’s nice out so why not. I drained out the Amsoil and drained the filter. Kept it since it was new anyway. Then filled the crank with the appropriate amount of this stuff, ran it for a bit, checked the levels and all. Then I decided to take a quick trip around to get the new stuff worked in well and into all the clutch plates. WOW! I didn’t make it a quarter mile before I noticed the shift massively improved, the engine braking and throttle response were substantially smoothed out and just more “fluid” throughout each gear and through the whole RPM range. If I had known how good this stuff was I would have ordered it before and used this right from the get go. If you have metric bike or any bike that shares the crank oil with the clutch, get this oil!!! I was really hesitant because of how good Amsoil is for cars/trucks. This stuff though…. This is stuff is something else entirely!

Perfect for motorcycle and cheaper than motorcycle shop

Used in a 2021 CBR1000RR, good for 3,000 miles. I ride spirited runs in the mountains and occasionally ride the higher RPMs on the highways. Oil tested by Blackstone Labs confirmed oil could hold up to 3,000 miles under my usage. Cut that in half if you're tracking the bike. Particles in the oil were below average as expected.

Il miglior olio motore in circolazione per i motori 4 tempi delle nostre supersportive, soprattutto oggi che le potenze raggiunte sono notevoli. Questo olio è particolarmente adatto per l utilizzo intensivo in piste e circuiti a patto che lo si cambi con frequenza, offre così la massima protezione alle componenti interne del motore. Personalmente lo utilizzo anche su strada ( sempre supersportiva) e lo cambio ogni 3/4000 km.
