Its a v-twin that pumps out 143HP at 10k rpm and 103NM at 8k rpm (as opposed to 57NM at 5.5k rpm on a stock DS650)

It would probably be lighter and a smaller package than the Hayabusa engine. (the busa is a 4cylinder right?)

ENGINE
Even the V60 Magnesium engine that powers the Factory has benefited from many improvements introduced to boost performance and achieve Euro 3 homologation at the same time. The new engine puts out 105.24 kW (143 HP) at 10000 rpm and develops a maximum torque of 103 Nm at 8,000 rpm. The exhaust system now has external catalytic converters that are installed nearer the collector pipes to cut activation time. The Factory is homologated to Euro 3 standards as a result, meaning lower emissions than ever before.

ya.. the V60 mag. is nuts.... i have a 07 aprilia tuono with this motor....
pipes and air filter and a remap is good for about 10 HP....

 

you can put ANOTHER 10 horsepower on top of that just by adding pipes and filter? rotax rules!
