Technical Overview
2005 GAS GAS 125 PRO Technical Analysis & Specification Breakdown
At the heart of the 2005 GAS GAS 125 PRO trial motorcycle, GAS GAS pairs a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches).
On the scales, the 125 PRO measures 63 kg (139 lbs) dry.

The 2.9-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
