Motus - American V-Four Sport Tourer?

[Raux]

I just noticed the alternator sitting behind the engine.  It looks just like a General Motors alternator.  I hope the future road bike can find something a little lighter than a car alternator.

700w is what i think the specs say on that. Lots of power for accessories.

I'll continue to hope for them to produce something great.  We need an American bike that everone can get excited about, or at least appreciate as being well made.  I like the V-four for being different, and the Corvette does just fine with pushrods.  Low-end torque AND good horsepower would make for a great ST.  500lbs is acceptable for a sport-tourer, my VFR was nearly that and it was only 800cc.

The car alternator is not good for a performance bike set up, but fantastic for touring.  Output at lower RPMs is much better.

I'd love to see it succeed too, but pushrods?  Really?  That's the best you can do?

No reason to do that other than attracting HD lovers.

Nice!  Any more info?  How is it installed and driven?

If your only going to have a 2 valve head, pushrods make a lot of sense. There are no chains or belts to replace, or break; and they are super reliable. On a Chevy, once they are installed, you never have to mess with them again until rebuild time. As much as Ive been down on GM recently for their build quality, the small block V8 has stood the test of time as a good reliable engine.

Belt driven I think. It's been a while since I looked at one closely.

Personally I'm digging the direct injection system. And the pushrods don't turn me off as much as the rest of you...

direct injection on a bike would be amazing, the hp gains over any other system are significant.

unless its a gear drive (horrid sound) there is still the crank to cam timing chain

and

something has to be spinning that cute little waterpump so there is a chain or belt in there somewhere

[Jarvicious]

Lets look at some specs:

Harley Fat Boy:
8xx pounds dry
89 pound feet
A little over 100 horse.  I think (going off what my mom told me hers does)

Triumph Rocket III
800 pounds dry
140 pound feet
140 horse (107 for the touring model)

Motus
I'll give them 550 pounds dry
140 pound feet
120 horse

Hell, even my old 88 BMW has like 50 horse pushing 500+ pounds and it's no slouch.  I'm sure she's going to do just fine.  Now cost.........

Squirrels?






No your right. You need a cam chain or gears. You can run a water pump off an external belt that doesn't need to be timed though. If it breaks its not a catastrophy, at least not right away.


And instead of agreeing with me, why are you not helping me shovel the snow out of my driveway and fixing the 4WD on my GMC?

[GAAN]

cuz youre on the wrong end of the state

simply move north and we'll get a proper 44 with hubs under there

problem solved




I wonder how a pair of those Motus motors hitched together would work in something with 4 wheels?

[MendoDave]

Well I bet one of them would work fine on my 320i. It only has a 4 cyl in it anyway.
