Welcome to Keefer Inc. Testing! Learn more here.

Thank you for visiting the Keefer Inc. website! I’m thrilled to bring this all to you, as it has been a dream of mine for some time now to bring legitimate tests to the masses via my very own outlet. As you can see, the focus of Keefer Inc. is in providing trustworthy opinions on a wide variety of bikes and products so that you, dear reader, can make the most informed purchasing decisions possible. Take a look around, and please feel free to send me some feedback or any burning questions via the contact page. Enjoy!

Here at Keefer Inc., we value honesty and integrity above all other virtues—nothing is more important to us than delivering legitimate, factual reviews. As such, any opinions that appear on this site have originated from or have been properly vetted by Kris Keefer himself, following the standards that he has developed over nearly two decades of professional testing and R&D. It is our solemn promise to always keep the end user in mind and to report all facts as we believe them to be true, never altering our opinions based on external or paid influences.

Please consider that motorcycle riding is inherently dangerous, and Keefer Inc. will not be held liable for any damages that may occur as a result of something you see or read on this site. For example, if you whiskey throttle your hopped-up 450cc thumper into a fence because the pipe we told you to buy had too much hit for your scrawny ass, that’s on you!
