Dirt Bike Fork Oil

Dirt bikes ride on rougher terrain more than any other type of motorcycle, hands down. When it travels over whoops or hits a 20-foot motocross jump, its suspension is tested in ways that a street bike will never face. That means that dirt bike fork oil needs to be specially formulated to meet the rigorous demands of off-road riding. No regular motorcycle fork oil will do.

    I'm surprised there is even any need to review this product. I've tried lithium, high temp red, numerous synthetics, nothing seems to stay put and work, like the Bel-Ray. Especially on shock linkages exposed to mud constantly.

    Work as expected

    Perfect oil and weight for my son's Honda CRF 230. We replaced the seals and oil in the front forks on his 2006 Honda CRF 230. Feels like new again.

    PJ1 Super Cleaner is better

    I bought this product thinking I might have found a less expensive version of PJ1 Super Cleaner and it ships fast. It cleans pretty well, along the lines of hot water and Dawn dish soap, or acetone which leaves a film. It doesn't not remove some oils from surfaces (still visible), washing others away. This is due to hexane and it's solvating properties. I've been working on vehicles 40 years including nearly a decade of professional shop in San Francisco on high end bikes where one doesn't just spray "carb cleaner" like Winder. Some chemicals work well with little or no side effects- this isn't one of them. Maxima claims "trade secret" in the MSDS, listing Hexane as 60-100% by volume, and 1-5% carbon dioxide. Hexane causes damage to all parts of the nervous system. Many reviews talk about "how good it smells", meaning they are inhaling it to some degree. This is one of the first products I have used in many years that has a definite, noticeable effect on me. I use fans to direct fresh air across my work areas when soldering or spraying chemicals, and I'm still dizzy & disoriented after using this stuff. Use caution, wear gloves, read the MSDS. Maxima's product is about half the cost of PJ1 Super Cleaner, but you don't need much PJ1 and it works better, including creating the cleanest base/head gasket surfaces you've ever seen.
