Look at the success rate of US bike companies with great ideas for great products.

Victory (great bike, but a harley clone)
Indian, same as victory.
Confederate, built on the Vtwin platform
Buell, great bike driven into the ground by harley, truley squandered potential
Fischer, a decent bike nobody ever heard of
Roehr, the american version of Bimoto, also nobodys ever heard of it

I love the idea of owning a small boutique brand bike, but I don't think I will ever, just too many variables.

I seriously considered a buell instead of the KLR, but even that, the most successful non cruiser american bike company has failed us.

If they're smart, they'll license that engine design to others. That would even be great in a small car, an ATV, small inboard...

Now there is an idea, start small, and if you are a sucess, build a bussiness from there!

It will be a great engine because what most of these guys here aren't understanding is the low end torque that you get from a push rod motor.

Either way I hope they pull it off and make it happen... WOW would it be amazing!

Mechanically the push-rod style motor is less simple just because there are extra parts & geometry involved vs. over-head cam designs. P/R valvetrains have more parts/sub-parts (typically lifter, pushrod, rocker-arm & all the associated bits), and more parts = more mass & friction/deflection/hot-spots/wear-points = generally less rpm/surface-speed attainable than more efficient OHC designs. But the geometry of the blocks & heads (both casting & required machining - really factors-in when considering oil-passages, I think) & cam-drive mechanism, and adjustment of valve clearance are generally simpler & more easily accomplished (or automatic, with hydraulic lifters/lash-adjusters). As for making torque - p/r don't increase the torque a motor produces, they're just generally used in large-displacement relatively low-rpm motors which tend to have more & are tuned for bottom-end torque. All that said, p/r technology still does a hell of a job in many applications, has for decades and will for many more - it's just not as well-suited to very high-rpm operation & is *relatively* 'old-fashioned' technology. Some of the best things are though!

O/H cam & shim-under-bucket is about as mechanically simple & efficient (fewest parts, least reciprocating mass/energy wasted) as you can get, but the manufacturing tech & precision required is a LOT higher to produce the parts (block & heads, mostly). Can be a real PITA to deal with clearance adjustment also, of course - what with having to pull elaborate air-boxes/hosing & throttle-bodies & shit just to *start* removing the camshafts (and usually cam chain/tensioner) + having to measure/calculate/replace shims which MUST be meticulously & correctly done. Believe me, sometimes I've *wished* I could just slide a couple tubes up & be done with a couple wrench-twists, without having to take much if anything off to get to them!

motocyz anyone? wanna bet it becomes electric prior to release?

Thanks kerry for a much better detailed post. It was more better. I heart pr and have had it on many motors both bike, car, truck, and tractor. I love em.

I luv this whole idea and concept. I wish them the best and hope to see this in a showroom. Hopefully they make good alliances.

They should start talking to erik being he's getting ready to bring a non-hd street buell back to the market.

Never going to do anything. I don't get my panties wet when I see Ehmurican on shit though.

Dey took our jubs!

I don't own one anymore and Don't mean to quibble but the Victory Drive train is hardly a HD Clone.
Overhead Cams,, gear driven primary and cassette tranny. Make it Very Different than any of the V twin Pushrod bikes, better to compair it tot he Metric Cruisers.
That said I would love to see Motus put out a bike. Test Dynos are notoriously optimistic. Even so a Production V 4 with even 100 ft Lbs of torgue could make a Fun Power Cruiser.
