Engineered by Ajp for the enduro - offroad motorcycle segment, the 2021 Ajp SPR 310R pairs a 297.6 cc (18.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 12.9:1 compression ratio.
Rider ergonomics and chassis geometry center around a 960 mm (37.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
