Built around Polini's minibike, cross motorcycle platform, the 2016 Polini X1R H2O relies on a 49.8 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.2 x 39.3 mm (1.6 x 1.5 inches) with a 15.2:1 compression ratio.
On the scales, the X1R H2O measures 43 kg (95 lbs) dry. Rider ergonomics and chassis geometry center around a 630 mm (24.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 900 mm (35.4 in) wheelbase engineered for quick, flickable steering geometry. The 3-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
