Yamaha shows ‘crossplane’ twin

Follow on from R1’s four and MT-09’s triple…

YAMAHA has revealed a new parallel twin engine that carries on the ‘crossplane’ thinking of its R1 engine and the new MT-09’s triple.

The firm is building a whole line of motors around the crossplane concept, and this is the latest, revealed in an event in Japan.

Details are virtually non-existent. We don’t even know the capacity of the motor yet, although it looks like it’s between 500cc and 1000cc, given its external proportions in comparison to the MT-09’s 850cc triple, photographed alongside it.

Of course, the whole ‘crossplane’ this is slightly diluted by both the triple and the twin. While the R1’s engine is quite innovative, replicating the power delivery of a V4, the MT-09, with its 120-degree crankshaft, is quite conventional for a triple. True, the crankshaft isn’t flat-plane, but it’s not as unusual as the R1’s design.

On a twin, the same idea surely relates to a 270-degree crankshaft, imitating the power delivery of a 90-degree V-twin. That’s the arrangement Yamaha already uses on the TDM900 and the Super Tenere parallel twins, so this new design isn’t likely to be as ground-breaking.

However, it bodes well for a new Yamaha, or even a range of them, potentially rivalling Honda’s new CB500 line-up.

The Triumph Bonneville America and Speedmaster both have 270 degree parallel twin crank. So nothing really new as a raw concept.

I kind of get the crossplane idea with am in-line 4 to mimic a V4, but a twin? Really? Erm, have to agree with @mfoobar here - what's actually new and innovative about this engine? Answers on a postcard, to the usual address...

270 degree crank to mimic a V-twin... simple! Don't think Yamaha claim that the 270 twin or 120 triple is new and unique to them, but the engines are. In either case, they'll probably be stonking engines!

The twin looks great. Not much bigger than a single cylinder engine of a few years ago. Would be great in a trail bike or supermoto.

Capacity between 500 and 1000 eh?

No shit Sherlock! :)

THe 270 degree parallel twin is one of the best engine arrangements ever built. PLEASE mr Yamaha, make a new sports tourer with it!

If they ever release the new bikes give a shout. Honda, Ktm, and to a lessor degree Kawasaki are already doing nice things in the smaller displacement arena. Yamaha seems to be treading water.

For many Yamaha riders, the 1970 to 1980 XS twins and triples were the best engines ever. This twin looks like the old TX 750 engine, later performed in the famous 1972 XS 650 with 60 HP, and often bored out until 980cc giving sidecar crossers 100 HP on the track. If Yamaha succeeds to make a 180 KG XT500 evolution
with this engine, many BMW F800 owners will turn back to Yamaha.
