Geco 250 Custom

2003 Siamoto Geco 250 Custom Technical Analysis & Specification Breakdown

Engineered by Siamoto for the custom - cruiser motorcycle segment, the 2003 Siamoto Geco 250 Custom relies on a 234 cc (14.3 cu in) twin, four-stroke powerplant. In factory specification, peak output is rated at 17.5 HP (12.8 kW) at 8,500 rpm while maximum torque reaches 15.1 Nm (11.1 lb-ft) at 7,500 rpm. With a specific output of 74.8 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Geco 250 Custom measures 154 kg (340 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
