Worth the cost Motorex is more expensive than other engine oils, for a good reason: it has exceptional reliability and quality. I use it for my BMW R1200GS Adventure, and so does everyone else I know who rides a Boxer! November 9, 2015
Good Stuff Pricey but it is going into the heart of your machine. My bike actually felt faster. It is quieter. December 1, 2014
