Things to know about an Oil Filter (And Aftermarket Parts):
All patents expired long long time ago. The parallel production is in quality of similar materials Vs' origine, because there is nothing to save there. The oil filter is built from a simple materials available and cheap for all. When it comes to new patent the pricing of the engineering development is entering into the new product price. Today there is no longer anything to develop in this component. It has reached to perfection.
Those who insist on paying more, pay mainly for "branding", it's a spin, just know that the extra money it's mostly for the "branding", because there are no quality differences that can be felt in them.
This is such a simple mechanical component, that it is easy to do a visual quality inspection for him, if It's look well built is good.
I personally use parts from parallel production wherever It possible, and when the price differences is Big. Or in the case of significantly improved parts, such as:
OR (Another example): A manual tensioner for a timing chain that is built alone D.I.Y at 4USD and even less than that, when the original tensioner costs 30USD, when the manual tensioner is no less quality (advantages and disadvantages)
The CBR250R is a budget motorcycle, and it is most legitimate to save on him an expenses.
The black color of the used filter, it is the color of the burnt and spoiled oil that you replace, it is not a substance that the filter stopped, it is the color of the old oil. Harmful aluminum chips etc (such as those that may block the passage of oil, or do great damage to the bearings), are stopped by the strainer(the Screen Oil filter). The other particles that are trapped by the oil filter are: Sand and dust particles, and micron chips of metal as a result of natural abrasion. The generic filter easily stops them all.
The Screen Oil filter:
Whoever getting 120% from his engine on racetracks will invest in expensive upgrades and have fun. Those who ride calmly, and see at CBR250R motorcycle as a cruiser motorcycle (because sitting upright and very comfortable for this purpose), are usually at 5-7 rpm, for them, from me, it is usually a different story.
