SPR 510R

More power and performance, all the time. The SPR 510R is the grown-up 4-stroke that AJP developed for extreme riders only. Easy going nature? Forget that. This Dirtbike brings together an ample supply of strong, very torquey power with handling and agility that is anything but heavy. It’s the perfect 4-stroke ripper for mud slaying, full-power riding enjoyment. Using a reliability-proved fuel Injected Mono-cylinder for a consistent, easy maintenance operation, the SPR 510R is fitted with a super-reliable 6-speed transmission as well as the ultimate progressive suspension setup developed by SACHS. Enjoy.

The DOHC 501cc Liquid-cooled engine shares much of its components and development with the also race-proven SPR310R engine but provides a significant increase in power and torque. In turn it gives the SPR510R its lightweight character and explosive attitude. Not for the faint of heart, really. With extreme power comes (usually) extreme responsibility so we fitted the SPR510R with a precisely tuned Athena ECU that allows our enduro riders to have control over the machine, anytime, anywhere.
