The S4R is the most powerful, best-handling Monster ever - the engine is the same as fitted to the 996cc Superbike, and that liquid-cooled, Desmoquattro, fuel-injected, L-twin was derived directly from the World Superbike champion race bikes.
There's grunt on tap whenever you need it. The S4R's engine delivers 113 horsepower, a full 12bhp more than its predecessor, the S4. At the same time, engine torque has risen by 0.38kg to 9.68kg at 7000rpm. When power like that is combined with the S4R's light weight of 193kg (423 lb) you get a bike that's made for adrenalin junkies.
The S4R's uncompromising style perfectly matches its sport riding characteristics. The classic trellis frame and central fuel tank show off the Superbike engine and curving radiator.
Another distinctive feature is the radical exhaust system, with a pair of alloy double stacked silencers on the right. Additional styling details include carbon fibre covers and a front fairing that provides decent protection, without detracting from the Monster's lines.
The front fairing also houses an instrument panel with new graphics and improved lighting. The four Ducati colour schemes of red, yellow, black or metallic grey joined by a fifth for 2004 - blue with white racing stripe.
The Monster S4R gets a chassis set-up like that specified for the best Ducati sport bikes, and that guarantees confidence inspiring roadholding and handling. The rear suspension gets an all-new tubular alloy single-sided swingarm that is light and rigid, complimenting the Ducati trellis frame. The swingarm is graced by a new Showa shock absorber, fully adjustable for compression and rebound damping plus spring preload to satisfy the needs of the most demanding riders.
The same goes for the 43mm Showa titanium nitride coated upside down forks - fully adjustable and racetrack ready. The S4R also allows ride height adjustment separate from spring preload, allowing riders to set up their Monster to any road condition or riding style.
The riding position and controls have been developed to ensure maximum control and improved ergonomics. New variable section aluminium handlebars carry brake and clutch levers that are four-way adjustable. The rider and passenger footrests are new for 2004, and the two-piece forging allows the rear pegs to be easily removed for track days. And let's face it - if you've got a S4R then you're probably going to take it on a track day. Have fun.
