Motul 5100 4T 10W-40 Motorcycle Oil - Technosynthese Semi-Synthetic with Ester - API SP JASO MA2 Wet Clutch Safe - Smooth Shifting Engine and Gearbox Protection for Street ATV UTV 1L

Worth the cost for the right stuff

As advertised, Motul 5100 Ester Blend 15W-50 (semi-synthetic) appears to be optimized for a shared-sump motor. I immediately noticed a quieter valve train with my Triumph air/oil-cooled motor. I have recently experienced clutch chatter during high operating temperature in slow speed maneuvering and clutch slip at takeoff prior to reaching full operating temperature. That has seemingly disappeared. Gearchanges are now accompanied by a "snick" rather than what had developed into a soft "clunk". As the miles have piled on, the transmission, although exceptionally smooth compared to many other modern machines, became slightly reluctant to shift smoothly. That has also now seemingly vanished. This particular machine calls for Semi-synth or full synth, shared-sump oil in either 10w-40 or 15w-50 weights. In Southern California, the "winter" weight of the oil is a non-issue, so I have taken liberty in the past with this. The previous fill was with Mobil 1 Racing 4T (PAO, or so we've been told) 10w-40, an oil that I have used for years with little complaint. If anything, my previous fills with Mobil 1 have felt like they are shearing down before 3-4000 miles, well before the recommended 6000 mile interval. In this machine, a previous Triumph twin, and other machines, I have filled with Redline (ester) 20w-50 & 10w-40, Mobil 1 4T 20w-50 (PAO, or so we've been told), Castrol Actevo (semi-synth) 20W-50 & 10w-40, and Castrol Power 1/RS (Group III) 10w-50, plus some others I fail to recall. All of them are fine oils for the application. At some point, the Mobil products resulted in clutch chatter and slip. At some point, the Castrol products seemed to shear down around 2-2500 miles. The Redline products never gave me an issue other than 1) locating some and b) paying the asking price. Motul 5100 is priced more competitively than all but the Castrol Actevo. However, Motul 5100's ester synthetic base and additive package is available at a price point that the competition doesn't offer. For the quantity, this oil is quite a bargain. Although not readily available at an auto parts store like Mobil, Castrol or Valvoline motorcycle oils, telegraphing an oil change and having oil shipped is a minor inconvenience in the context of the benefits of Motul. Frankly, I've avoided Motul for this reason, as well as the fact that they market so hard for independent shops to carry the product line. Having worked as a motorcycle mechanic for a spell, Motul products seemed cheap for this reason, despite being able to buy at cost. However, customer comments on how much better the motor "feels", even with Motul's standard mineral product, should have clued me on. I guess I was ignoring how much harder the huge companies market their motorcycle products to chain stores. So much for standing on principle... Whether Motul 5100 shears down quickly in this bike remains a to be seen. I'll add to this review when I know more. Hope this helps you make a good decision.

Why did you pick this product vs others?: I have been riding for almost 50 years and have used various oils in that time. In my personal opinion, Motul 5100 and 7100 oils are the best out there for motorcycles. Provides my cycles with year round protection, quick starts, smooth shifting, and quieter engine noise.

i use this oil in my zzr 1200 and no motor issues also use in my gpz 1100 with 120 thousand miles since new in 1996 and still runs great with no oil burn

I have been riding for 40 years. Here is a picture of my first street bike.I have tried every oil under the sun. The motul is great. It is a good value and reduces engine noise. I do change my oil as recommended or even earlier then most riders,That being said the oil color still was clean.. I will buy Motul again.

I use Motul oils in all of my motorcycles. Excellent quality and film strength and able to handle high temps whether on street bike or dirt bike. Worth the extra $ in my opinion.

Doesn’t need any hype. Doesn’t need any gimmicks. It’s the best oil money. If you care anything about your bike, you will buy MOTUL.

Works well in my Honda 919, not much more expensive than the stock Honda oil, all reports say that I'm getting excellent performance for everyday riding. No problems with shifting. Assuming it lasts through riding season, and I have no doubt that it will, this'll be my go-to for oil changes along with the good K&N filter.

Reste et restera une bonne marque
