"R" engine

With its 1200 cm3 Testastretta 11° DS twin-cylinder engine in the "R" version, the new Monster 1200 R takes the naked concept to the extreme. The new engine is in fact able to express its full potential with a full, fluid supply even at low speeds, perfect for riding on the road but also between the kerbs of the track.

Racing Performance

The Monster 1200 family is powered by the second generation of Testastretta 11° DS engine, smoother and with dual spark plugs and a secondary air system. Dual Spark (DS) ignition uses two plugs per cylinder to ensure complete combustion in a very short time. A secondary air system similar to that of the 1299 Panigale has been introduced to optimise operation and reduce cyclic combustion variability without affecting emissions. A controlled flow of fresh air is supplied to the exhaust duct to enable complete oxidisation of hot unburnt gases, to effectively reduce hydrocarbon and carbon monoxide levels. The Testastretta 11° DS engine that equips the Monster 1200 family is unique to those bikes, as its structure is engineered to be a structural element of the frame. The "R" engine version is tuned for power and torque and to be Euro 4 complaint. Engineers increase air-intake, burn and exhaust efficiences. The engine breathes further better thanks to new elliptical throttle bodies and air ducts Ø 56 mm equivalent, larger than the Ø 53 mm standard circular system. The cylinder heads are new too with increased air inlet ducts to perfectly match the different in shape and dimension air ducts. A lower cylinder-crankcase gasket rises the compression ratio to 13,0:1 respect the 12,5:1 of the standard 1200 cc engine. The exhaust system is completely new with larger Ø 58 mm exhaust pipes and a new Euro 4 complaint silencer. The Euro 4 preparation is completed with engine noise reductions as a dedicated clutch cover and new pistons with graphite surfacing.

Power and torque

The "R" engine version delivers a wide spread of power and torque with a peak of 160 hp @ 9.250 rpm and 13,4 kgm @ 7.750 rpm of torque for great performance and fun. At low, medium engine revs the “R” has a strong responsiveness with the 75% of maximum torque already available at 3500 rpms.

Exhaust system

The "R" engine version is coupled via Æ 58 mm pipes to an impressive side-mounted 2-1-2 staggered shotgun exhaust that makes no secret of the performance of which the new Monster 1200 R is capable. The bigger in dimension silencer to be Euro 4 compliant has a sport and “mechanical” design, consistent with the "nerve" forms of the tail. The engine management system dedicates a lambda probe to each header, providing precise fuelingwhile an electronically controlled mid-section valve optimises exhaust pressure throughout the rev-range.
