See what dirt bike riders are saying about AMSOIL Motorcycle Octane Boost.
"My CRF450R was pinging hard on pump gas. Added MOB and the knock disappeared completely. Bike pulls harder now and throttle response is crisp. Race gas alternative that actually works."
"I run high compression pistons and need the octane boost. MOB lets me run 91 pump gas without detonation. Saves me a fortune compared to buying race fuel every weekend."
"Trail ride in high elevation where fuel quality varies. Always carry MOB in my pack. Keeps my bike running smooth no matter where I fill up."
