Isn't there a reason that you want the rotating mass to go the same way as the wheels?
Ie; = - = not = | = I know that Moto Guzzi runs theirs that way but don't they have to add counter-rotating mass to make it work? Won't this cause handling issues on a "sport" tourer? ![]() |

![]() That seems to be the trend. Whichever magazine had the all electric issue recently was littered with companies following that business plan. 1) Develop a gasoline powered motorcycle. 2) Try to take deposits on it. 3) Realize deposits aren't rolling in for a Desmosedici priced piece of vaporware no one has heard of. 4) Make a shitty electric version. 5) ??????????????? 6) Profit! |

I'm their target market.
![]() If its a solid bike, WITH ABS, I'll definitely consider it. ![]() (As in what idiots would even contemplate building a "sport tourer" without ABS currently?)

RE: 90 Degree opposition crankshafts...
Yes, they do twist / lift the bike's chassis a bit. It varies by design. Having had both Boxer and K-Brick engined bikes (both having crankshafts rotating perpendicular to the rotation of the wheels), neither design is "startling" in this respect, even with violent applications of clutch & throttle. Yes, its there. Will you notice it after more than 30 minutes riding the bike? No. ![]()

I'd speculate their decision to go with pushrod design was based on 1) cost/complexity of casting/machining, 2) Overall simpler (considering no ohc drive) & more compact motor, especially with the heads hanging out either side of the bike, ala MotoGuzzi. The heads have to be considerably taller with OHC, especially with a relatively small budget which wouldn't allow for repeated prototyping & material minimization. Way easier, esp. in a V-design, to just stick a cam in the valley right over the crank & with a simple chain or gear drive. Works just fine to, as long as you're not trying to spin it way up. Maybe a distant 3) it's 'murican.
The counter-torque is just nature of the beast & a reaction to the inertia of the crank/flywheel spinning-up. I've felt it on a boxer, and though noticable it wasn't a big deal. That's a V4 mounted relatively high vs. the very low-slung BMW design - and did you see the size of the flywheel in the video?! I bet it has a good bit of counter-torque, but that might just add to its character. Wouldn't be a big handling factor so long as you're changing rpm drastically in a curve - also side-ways V design would lessen the gyroscopic resistance to side-to-side transitions too, vs. typical transverse crank mounting. All technical BS aside - it does look pretty bad-ass, producing their own engine in-house is impressive, and kudos to them for doing *something* to produce a sporting American motorcycle. I hope they do well & we see good things come of their efforts! ![]() |

i mean we can armchair race a new engine, but if its not ment to be racing arent we just spinning our wheels??? right tig? lol ![]() |
