The 1998 Harley-Davidson FLHTCUI and its Evolution engine raised the bar for American touring bikes. At midyear came a new wet clutch resulting in lighter lever action and easier shifting. Harley termed it the Softail frame, and it would soon be fitted to a wide variety of custom machines-and still is..
In this regard, do Harleys have dry clutches?
The open dry clutch is noisier, and makes some dust. A wet clutch is quieter, and should last longer, with less adjusting. A wet/dry clutch will function with some oil on it, that's how Harleys ran for years.
Likewise, what is the benefit of a wet clutch? The oil's primary purpose is to cool the clutch plates, and because of this cooling effect wet clutches can take a lot of abuse, like the kind you'd dish out in stop and go traffic. Wet clutches generally have a nice wide friction zone that makes them pretty easy to use.
Also asked, do all motorcycles have a wet clutch?
Some racing cars have wet, multiplate clutches like motorcycles and some motorcycles have dry clutches. The reason most motorcycles have wet clutches is that the clutch is not on the crankshaft. It is connected to the crankshaft by a gear.
Why do Harleys have oil tanks?
Harleys are dry-sump bikes, meaning the oil is stored remotely and pumped in. All older Harleys and some new ones locate the oil in a tank that is higher than the bottom of the engine cases. Thus, the oil blows out the crankcase breather or air cleaner in copious amounts.
