Ducati’s 130bhp Monster S4RS Testastretta made its debut before the world’s press at the Milan Bike Show in Italy on Tuesday (Nov 15).

And we were there to bring you the first pictures as it was unveiled.

The S4RS gets its Testastretta name by virtue of the fact it shares the Testastretta engine with Ducati’s flagship 999 superbike.

It retains the trellis frame and single-sided swingarm of all Monsters but has a black frame and forks. It uses a 999-inspired front end, Y-spoke wheels, and vertically-stacked twin cans by Termignoni.

The front end takes its parts from the 999s; Ohlins 43 mm upside-down forks with low friction TiN treatment with adjustment for preload and damping.

Front brakes are twin 320 millimetre discs. The reservoir and master cylinder are specially designed for this version of the Monster, which has radially-mounted front brake calipers.

The rear shock is an Ohlins item with adjustment for compression, rebound, and preload.

The 130bhp Testestretta engine on the S4RS has a dedicated oil cooler designed to work best on a naked machine. Airbox and throttle body (with IWP 189 injectors) are similarly tweaked for naked bike performance.

Detailing includes a triangular oil cooler and carbon-fibre silencers cover, front mudguard, timing belt covers and exhaust pipe heat shield. The cooling circuit ducts are now forged in aluminium rather than moulded in rubber.

The dash has the same instruments as the S2R but with dedicated graphics. The tank incorporates a new fuel pump.

It is available in red, black, and an all-new pearl white.

Testastretta (literally “narrow head”) derives from the specific layout of the timing gear, which results in a reduced angle between the valves in the cylinder heads. The result is a compact and clean combustion chamber aimed at optimising combustion and compression efficiency.
