Experience performance for four-cycle motorcycles

Mobil 1 Racing™ 4T 10W-40 motorcycle oil is designed primarily for on-road, high-performance, four-cycle sport bikes. It also may be used in other types of on- and off-road four-cycle motorcycles that specify the use of 10W-40 engine oil.

The unique, synthetic structure of the Mobil 1™ motorcycle oil formulations offers advantages beyond conventional motorcycle oils of similar viscosities.

This full synthetic motorcycle oil helps provide excellent performance in motorcycle engines that are either:

  • Designed with a common engine/transmission lubrication system, or
  • Designed so that the engine lubrication system is separate from the transmission system. (Follow the manufacturer's recommendation for the type of fluid to be used in the transmission.)

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.

Rated 5 out of 5 by from Best V-Twin Oil I've Ever Used! I have a 2004 Yamaha Road Star Midnight Silverado XV1700 V-Twin. I had used a couple of other brands (brand "C" and brand "RP"). They did the job, but I wasn't 100% happy with their performance. I use Mobil 1 Extended Life oil in my GMC truck, so I wanted to try Mobil 1 in the bike. I can honestly say that I'm now 100% happy with my oil's performance. On start-up, the engine is quieter. On the road, the engine runs cooler, quieter, and smoother. The transmission shifts smoother, too. Upon changing the oil, I even found the used Mobil 1 to be cleaner than the other brands I'd used when changing them. Overall, this is, in my opinion, the best oil you can use in a V-Twin engine.

Rated 5 out of 5 by from Switched to Mobil 1 at first service! I have a 2013 H-D Ultra Classic with the 103 V-Twin and switched to Mobil 1at the first 1000 mile service. I immediately notice a reduction in engine heat in this air cooled motor and also used on the transmission and primary. Neutral has never been easier and the transmission oil looks like it was never used. Mobil 1 is cheap insurance and I like the convenience of using one oil in "all 3 holes". I keep a spare quart on hand though my bike never needs topped off. I'm a believer and my much cooler bike agrees.

Rated 5 out of 5 by from Great oil worth the extra cost I switched from Valvoline synthetic to Mobile 1 in my Triumph Speed Triple. There is a noticeable difference in clutch smoothness and engine performance. My bike runs much smoother and quieter than before, this is especially true during the initial warm-up procedure. Mobile 1 stays much cleaner than any other oil I have used in the bike. I've found that after a year the oil is still good, though I replace my oil once a year and use a K&N oil filter (I put about 3,000 miles a year on my Triumph). I'm going to stick with this oil, my bike loves it!
