At the heart of the 2025 Triumph TF 450-RC cross - motocross motorcycle, Triumph relies on a 450 cc (27.5 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches) with a 13.1:1 compression ratio.
On the scales, the TF 450-RC measures 108.4 kg (239 lbs) wet (curb). 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 1,492 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
