Similar to the first one, the Maxima Racing Oils has a dedicated oil made for V-Twin transmissions. Overall, the Spectro Oil will work for everyone, and if you doubt what to get, this might be the safest one to get for your transmission.

And with the thick oil, the gears will be protected from having shock loads. It also makes a high strength film between the gears thatвЂ™ll also prevent the gears from jumping and therefore shift more smoothly. This oil has additives thatвЂ™ll help maintain clean gears. The Spectro Oil R.HDPG6 is made to exceed all OEM and Harley Davidson warranty requirements on fluid replacement, so you can rest easy that this will not void your warranty in any way. As we all know, high-performance transmissions will only go well with heavy-duty thick oil as they resist thinning better. The SAE rating is at 75W-140, making it highly versatile, as you can use this well on weaker transmissions while itвЂ™ll handle high-performance transmissions better. The Spectro Oil R.HDPG6 is a heavy-duty transmission oil aiming to provide a better shifting experience and a quieter transmission noise. This oil is best for people who love to push the engine and transmission to the limits.Дid you like both transmission oils weвЂ™ve mentioned so far? Then this last one may be the best for you as it brings the best features of the two previous oils together. This oil will essentially work with every Harley Davidson model, even models with the Twin Cam engines and Evolution engines will work well with the Red Line V-Twin Transmission Oil. In the end, all I can see more benefits than drawbacks with this transmission oil. And lastly, being a thicker transmission oil, gear jumps will also be much rarer. That thicker film will protect your gears from clunking and colliding with each other eliminating clunky shift noises, and the gears will have a much longer lifespan. Due to the thicker viscosity, the transmission oil will have a much thicker film of oil on your gears. Since this transmission oil is thicker than conventional transmission oil, it will also provide a much more effective cooling property for a longer time. YouвЂ™ll have less transmission noise and more confidence in driving. And while driving, you can notice the difference in transmission and engine noise. It will prevent any damages caused by shock due to hard shifting. The ShockProof naming is there because the oil viscosity is thicker than standard transmission oil, and this property will help dampen vibrations from everyday use. And we recommend their V-Twin transmission oil with ShockProof. Helps quiet noisy engines.Red Line has a lot of trusted customers, especially among motorcycle riders. Red LineВ® 20W60 Motorcycle Oil is made especially for air-cooled engines operated in extremely warm environments such as those encountered during the summer in the Southern US.
