Crisis requires, Yamaha has temporarily shown a certain restraint in terms of creativity. But the situation will change in 2014, thanks in particular to the arrival of two new engines in Iwata‘s range: the new 3-cylinder unveiled on the and a new medium-displacement parallel twin. !

Like the 4-cylinder of the, then the 3-cylinder of the, this new parallel twin (pictured opposite next to the "3-legs" of the MT-09 with the M1 in the background de Lorenzo) would use Crossplane technology.

Used for the first time by Yamaha in 2004 on the MotoGP YZR-M1, this technology is based on a crankshaft timing known as "cross plane": the crankshaft pins are positioned at 90 ° relative to the crankshaft. next.

Thanks to this arrangement and to an asynchronous ignition sequence, it is possible to make a multicylinder engine more torque and especially to make the use of its power easier. Better filled at low and mid-range than a traditional 4-cylinder wedged at 180 ° (but less explosive at the top), the 4-cylinder Crossplane does indeed offer an excellent "throttle-rear wheel" connection..

Not to spoil anything, its behavior similar to that of a V4 makes this mechanism alive and endearing, a feeling amplified by its hoarse and deep sound worthy of a racing motorcycle..

On a parallel twin, this Crossplane setting could provide an additional smoothness compared to a twin of the same architecture like that of the Kawasaki ER-6 or Honda CB500.

Motorcycles that Yamaha is openly targeting with this new engine, which will certainly initially equip a small roadster intended in particular for .

No official information has yet filtered out on this new twin, the publication of the first photos of which by our Japanese colleagues of would be the consequence of a "leak" from a Yamaha technical meeting….
