Only some of the C4 corvettes were OHC. The last 2 generations have been nothing but OHV. The reason they went back was because of less maintenance and less cost. Not to mention the new Corvette OHV motors get MUCH better mileage. |

Just playin the devils advocate, I love the sound and torque you get out of a pushrod motor, I was just wondering why motus chose the motor they did. Seemingly they will have the only V4 type motor in the sport touring class, an no doubt has a hell of a bark. Just wondering how it will fare with individuals who are content with riding a motorcycle without any soul. I would own one if I could afford one, but what is the allure to others that are loyal to other brands. |

I don't think peoole riding a soul-less bike will pay for a Motis . |

They didn't choose it, they developed it from scratch to meet their vision of motor perfection. It looks to me like it has plenty of soul. People who are content riding poorly designed bikes will have no interest in the Motus; that's a good thing. |

I dont think they will have issues selling them so the people who ride bikes with no souls (whatever those might be) arnt really a consideration. What i really like about the motus is the automotive styled alternator. No more stator woes. |

OHV = Tractor??? WTF? I once read a fantastic article a long time ago that was an old article then - it was written in the early 90's I think comparing the OHV Corvette to the DOHC (and maybe turbo charged?) Nissan 300Z or something. The jist of the article was that even though they made the same hp, weighed about the same and despite the Vette using old tech, the Vette was still the faster car. Reasons were abound about low-end torque, bigger displacement, etc. But the bottom line is you can get tons of power out of a pushrod engine for less $. Ford's new 5.0 is an AWESOME engine, but compare the cost of the heads to those on a Gen IV GM small block. A cam for an LS-serieis engine runs about $600 with everything you need... trying buy 4 for that price. I'll agree it's lower tech, no doubt, but that doesn't mean it's worse. I've also read that OHV was chosen to keep the engine short for aerodynamics in corvettes - not as important in a bike, but in a v-configuration, an OHV motor is the more compact choice. Multi-valve engines make sense when you're trying to make a lot of horsepower with small displacements high in the rev range. The smaller overall valve area of an OHV engine means higher intake velocity at lower RPMs (this is why things like V-TEC exist) to make the power there. For this kind of bike, that sounds perfect to me. Honda's ST1300 (and the ST1200 before it) both use a V4 engine as well, though it's DOHC. And the fuel mileage on this engine should be insane. I have a 2002 Camaro SS, 5.7 liters and rated for 345hp from the factory and I'll manage 28mpg on a highway trip. My girlfriend's Pontiac G6 with a DOHC 2.4 liter 4-cylinder does roughly the same. City driving is a whole 'nother animal, haha |
