The Honda Sonic is a 125 cc, later 150 cc sport underbone designed for the Southeast Asian market by Honda. It is the part of the Nova series of sports oriented underbone motorbikes produced since the mid-1990s.

The Sonic is fitted with the European CBR125R and Indonesian CS1 4-stroke engine. It was adapted to liquid cooling due hotter weather conditions. The single-cylinder engine redlines at 10,900 rpm.

The engine utilizes an overbore design with two bigger valves. It also has a bigger Keihin carburetor with 28 mm venturi diameter.

The Sonic comes in two models, RS and RS Super.

The Sonic 150R was launched in August 2015 in Indonesia. It is powered by a 150 cc liquid-cooled, DOHC, 4-valve, single-cylinder engine mated to a 6-speed constant mesh transmission. The Sonic 150R is built at Honda's Karawang plant, West Java, Indonesia. In the Philippines, the bike is named RS150 (not to be confused with the RS150R sold in Malaysia, as it is a rebadged Winner that sold in Vietnam).
