Engine
The new engine technology from M1 decentralization, the same straight four 998cc Cross crankshaft 270 ° – 180 ° – 90 ° – 180 ° firing interval ranging from design. Cross crank the engine can be said that with the heart, through the cross crankshaft configuration to achieve the throttle opening and the rear output close to 1: 1 ratio. This represents the power R1 can be more direct feel knight grasped, so that up to 200ps of horsepower can be fully realized. On the M1 intake design is also imported to the new R1, the new intake system to adjust the amount of air intake characteristics, so that the overall optimization, thereby reducing loss of horsepower, making the new engine under Excluding Ram-Air could have 200ps of horsepower output. The new cross crankshaft R1’s new engine is not just bore, stroke, compression ratio change, even the most important cross-crank is also different from the previous generation. 2015 R1 crankshaft inertia is set lower than the previous generation 20%, through the close of the outer cylinder lightweight balancer shafts, to react quickly while maintaining linear engine torque output.

The new cross crankshaft using titanium rod.
Pioneered the use of commercially available titanium rod.13
212015 R1 using high strength lightweight titanium connecting rod fracture type, lightweight than 40% of the original steel rod, so that the engine can play to a higher speed, but also faster reaction. Breakages style design also provides greater precision connecting rod big end, and to avoid deformation of the connecting rod big end at high rotational speeds, in ensuring performance and reliability. High-performance cylinder head in order to improve combustion efficiency, 2015 R1 with a set of compression ratio up to 13: 1 in the cylinder head, inlet and exhaust doors also have increased, respectively, 33mm and 26.5mm. In addition, 2015 R1 engine intake and exhaust valve angle is smaller, so that the new engine has a more compact combustion chamber. This design allows the oil and gas can be more smoothly into the combustion chamber, and improve the overall speed and efficiency of combustion, and then let the engine with high output and good torque.1814
