Vehicle Information
Aprilia Tuono 125 Motorcycle - Street (2004-2005)
The Aprilia Tuono 125, produced from 2004 to 2005, is a dynamic naked motorcycle sharing its core engine and chassis with the RS125. Both model years were powered by a consistent liquid-cooled, two-stroke, single-cylinder engine with a displacement of 124.8 cc (or 125.1 cc). This engine delivered approximately 14 hp in its restricted form, and up to 28 hp (or even 35 hp for some 2005 models) when unrestricted. During this specific period, the Tuono 125 was primarily offered as a single model, without distinct trim levels. There were no significant mid-cycle generation or engine changes reported between the 2004 and 2005 model years; the engine, chassis, and six-speed manual transmission remained largely consistent, with only minor aesthetic differences like color options. Q: How can I confirm if a part fits my Aprilia Tuono 125?
R: To ensure perfect compatibility, please use the year and edition selector at the top of the page.
