There used to be a bit of a gap in the AJP family between the air-cooled SPRs and the rally-inspired PR7 650, but the new SPR-R line from AJP completes the model lineup.
The new SPR310R is everything a midsize enduro bike should be! It all starts with the motor; the 310cc displacement strikes perfect balance – it has the fun, responsive feel of a small bore with a boost in power and torque. The DOHC fuel injected powerplant provides precise power for trail riding, while still revving to the moon in an Enduro Special Test.
Razor-sharp handling matches the SPR310R’s motor. Basically a downsized version of the PR7s aluminum/steel hybrid frame design, the unique chassis of the SPR310 houses the fuel tank in the rear to lower the center of gravity and centralize mass. This allows for a lighter feel and more precise turning. Up front where the fuel tank resides on other motorcycles is where you’ll find SPR’s air filter. The uniquely designed airbox makes filter changes a snap with no tools required.
