AMSOIL Releases New Transmission Oil For Dirt Bikes

AMSOIL Synthetic SAE 80 Dirt Bike Transmission FluidAMSOIL has released a brand new synthetic transmission oil for dirt bikes and motocross motorcycles for the 2016 season. The AMSOIL Synthetic SAE 80 Dirt Bike Transmission Fluid is a high-quality gear oil for 2-stroke transmissions and also for 4-stroke bikes that have a transmission fluid that is separate from the engine oil.

Why Choose The SAE 80 Viscosity?

When choosing the best balance of friction reduction versus wear protection, SAE 80 seems to hit the sweet spot. Prior to the release of this Dirt Bike Transmission Fluid, a common recommendation by AMSOIL was their Synthetic 10W-40 Dirt Bike Oil. This product is an outstanding 4-stroke engine oil and also an elite transmission fluid.

Many assume that 10W-40 Motorcycle Oil is thinner than SAE 80 transmission oil, but the opposite is true. Gear oil and motorcycle engine oil use a different grading scale to prevent confusion and misapplication. The viscosity of AMSOIL Synthetic SAE 80 Dirt Bike Transmission Fluid is 10.3 centistokes at 100°C while AMSOIL Synthetic 10W-40 Dirt Bike Oil is 14.2 centistokes at 100°C. When comparing the two products on a viscosity chart, the 10W-40 Dirt Bike Engine Oil’s viscosity is actually closer to an SAE 90 gear oil.

What Kind Of Dirt Bikes Would Use This Transmission Oil?

Four-stroke dirt bikes and motocross bikes that separate the engine oil from the transmission fluid (such as the Honda CRF 250/450 series) as well as all 2-stroke dirt bike/MX transmissions.

Why Do Honda CRF 250 & 450 4-Stroke Dirt Bikes Use Separate Transmission Oil?

Most 4-stroke dirt bikes employed a common sump, meaning that one oil (usually a 10W-30 or 10W-40) is used for both the engine and transmission. This has always been the case for most motorcycle brands except for one. Honda CRF 250cc and 450cc dirt bikes and motocross race bikes separate the engine oil from the transmission oil and this makes perfect sense when you think about it. The engine oil does not have clutch plate material and metal filings from gears in circulation. The gear mashing in transmissions also tends to shear-down the oil’s viscosity. On the transmission side, the oil would not be contaminated with fuel dilution and combustion by-products. The transmission oil would also not be exposed to the high heat of the engine. Therefore each oil can do its job without being saddled with the baggage of the other compartment.

The advantage of a single oil sump in four-strokes is that they have the simplicity and convenience of changing just one oil type. They also have a large oil capacity on reserve, rather than two smaller oil sumps.

Best Oil Combination For 2-Stroke Dirt Bikes

Two-Stroke Dirt Bike/MX Engines- Use AMSOIL Dominator Synthetic 2-Stroke Racing Oil at 50:1. Some riders mix at 40:1 with excellent results. Dominator withstands extreme heat, big horsepower and prolonged high RPM. If you work your engine to the limit, you will be very pleased with Dominator.

Two-Stroke Dirt Bike/MX Transmissions Use new AMSOIL Synthetic SAE 80 Dirt Bike Transmission Fluid.

Best Oil Combination for Honda CRF 250 and 450 Series

Honda CRF 250 and 450 4-Stroke Engines- AMSOIL Synthetic 10W-40 Dirt Bike Oil combats heat and wear, while lowering friction and maximizing power output. This is the exact formula used by the Geico-Honda pro racing team and it will do a great job for you.

Honda CRF 250 and 450 Transmissions- Use new AMSOIL Synthetic SAE 80 Dirt Bike Transmission Fluid.

AMSOIL Introduces New Synthetic Oil For Dirt Bikes

, ,

AMSOIL Synthetic 10W-60 Dirt Bike OilAMSOIL has released a brand new synthetic oil series designed specifically for 4-stroke dirt bikes. AMSOIL Synthetic Dirt Bike Oils are now available in 10W-40, 10W-50 and 10W-60. These motorcycle oils are designed to withstand the abuse inflicted upon dirt bikes and are suitable for everyone from world-class motocross racers to casual trail riders. These oils deliver AMSOIL’s famous synthetic protection of 4-stroke engines, gears and clutches, buttery smooth shifting and maximum clutch conservation.

Frequently Asked Questions About AMSOIL Synthetic Dirt Bike Oils

Question: AMSOIL already offers their Advanced Synthetic Motorcycle Oil 10W-40. What is different about this new Dirt Bike 10W-40 Synthetic?

The new AMSOIL Dirt Bike 10W-40 formula places more emphasis on clutch preservation. Dirt Bike clutches can be subject to tremendous abuse. Many MX riders use persistent clutch slippage to moderate traction and maintain speed through corners. Hard riding through deep mud and sand can fry a clutch in mere minutes. One of the primary goals of these products is to dissipate heat in clutches and maintain its frictional properties to prevent slippage. Maximum power output and consistent clutch-lever feedback is the result.

Question: Does the introduction of AMSOIL Dirt Bike Oil imply that their current Advanced Synthetic Motorcycle Oils are insufficient for off-road use?

Not at all. As AMSOIL was adding 10W-50 and 10W-60 Dirt Bike Oils, it only made sense to include a Dirt Bike 10W-40 so that they could offer a full suite of oils for off-road motorcycles. The current AMSOIL 10W-40 Synthetic Motorcycle Oil has been used in professional motocross competition for years with outstanding results. Marcel Irnie (who happens to be one of North America’s fastest pro road racers) has told us that he can get a full season out of a set of clutch plates using the current AMSOIL Advanced Synthetic Motorcycle 10W-40. If you know anything about AMSOIL, it’s no surprise that they are always looking for a ways to raise the bar. So the release of this Dirt Bike 10W-40 is in no way an indictment of the current Advanced Synthetic Motorcycle 10W-40 Oil or its prowess in off-road applications.

Question: Can I use AMSOIL Dirt Bike Oils in my street bike?

Absolutely. AMSOIL Dirt Bike Oils can be used in any street bike, road racer, supermoto, scooter or ATV that calls for 10W-40, 10W-50 or 10W-60 4-stroke oil. These oils meet or exceed the JASO MA, API SG, SJ, SH, SL specifications.

Question: What is drain interval for AMSOIL Synthetic Dirt Bike Oils?

AMSOIL Synthetic Dirt Bike Oils should be changed at the interval suggested by the motorcycle manufacturer.

Question: Are these Dirt Bike Oils suitable for use in two-stroke motorcycle transmissions?

Yes. These oils are designed for maximum transmission and wet-clutch protection, so they are optimum for this application.

Question: Can AMSOIL Dirt Bike Oil actually improve the performance of my motorcycle?

Yes and on a number of fronts. 1. The 100% synthetic formula reduces friction in your engine, so it can operate at peak output. 2. Shifting is improved, even under heavy loads. 3. As mentioned, this oil is designed to keep clutch plates from expanding due to heat and slipping, so power is put to the ground and not compromised due to clutch slippage.

Question: Is this the same motorcycle oil used by the Geico Honda Pro Motocross team?

Yes. AMSOIL has always had a policy of providing the same oils to their sponsored professional race teams that you and I can buy. MX superstar Eli Tomac and the rest of the Geico Honda team were instrumental in the development of this Synthetic Dirt Bike Oil formula.

Question: What container sizes are offered for AMSOIL Synthetic Dirt Bike Oils?

These oils are available in single US quarts (946 ml) or in cases of 12 US quarts.

Question: Where can I buy AMSOIL Synthetic 10W-40, 10W-50 or 10W-60 Dirt Bike Oil in Canada or the USA?
