I agree with 440Magnum that this has been beaten to death and also with dwendt44 that there is little difference. Purolator list the ML16822 for my bike. If you look at it and also the L10241 on their web site, they have exactly the same threads, relief valve pressure, etc. Purolator says not to use a Pureone on a bike but not a Classic. Their reason is: "If you're thinking you want to install a PureONE oil filter on your bike, please think again. PureONE oil filters are designed for vehicles, not bikes. Because of PureONE's high efficiency, the motorcycle oil pump may not be able to handle the pressure. The Purolator motorcycle filter line is designed to meet the specific needs of a bike; therefore we highly recommend the use of a Purolator ML filter over a PureONE oil filter." I've been using using a Mobil 1 M1-102 for over 1K miles so far with no problems. I plan on using the L10241 on my next oil change.
