180 hp Harley powered American sportbike?

[PiZdETS]

Fuck yeah. The Roehr 1250sc (http://www.roehrmotorcycles.com/page4.html), completely American made, supercharged Harley revolution engine.

Cant find many pictures at all, looks like a lot of design cues borrowed from Mv Augusta

The Roehr 1250sc pre production prototype has been completed and plans are to begin production late this year. The bike is powered by a 180 hp supercharged Harley Davidson Revolution engine. This should be one extremely interesting motorcycle. I like the looks and I really like the blown Revolution engine. Final price has not been set.
Let’s see, a 180 hp supercharged American made V-Twin sportbike. Yep, I like it!

And this "making the Roehr 1250sc the fastest and most powerful sport bike built in America." makes me laugh...let's see faster than buell...fischer...and....?? Not really saying much.
It really is pitiful how tiny American contribution to the sportbike field is. We basically just modify Italian or Japanese designs and call them our own. Hope this starts a new trend.

I sticking with the Harley tradition of charging $1000/HP on there bikes that thing should be about $180,000.... No thanks...

[papapoi]

looks like a bobo ducati

[marko138]

Great looking bike...with what appear to be solid numbers...but yes, it's extremely expensive. Like 40 large or some shit. Fuck that.

[Captain Morgan]

Ohlins, Marchesini, Brembo, all stock...well, that should be an affordable bike.

Lets see, GSXR1000 - 07 holdover $9800
Ohlins shock and fork internals - $3800
Titanium full system - $1125
Power commander/cust dyno tune $ 450
Suzuki/Yosh Race ECU - $950
Marchesini Rims - $2200
Track side Pilot Race Tires - $ 350
Proud to be an American Flag Stickers$ 7

Total $18,682.00

Leaves $21,318 for track day fees, travel expenses, drinks, and lap dances.....:zowned:

"Deposits to reserve your V-Roehr 1250SC are now being accepted. This $4500.00, fully refundable deposit, will reserve your limited production V-Roehr Superbike on a first come/first serve basis. "


Yeah, gonna be expensive.

[Dave]

a completely american made bike, constructed from everyone else's parts :lmao: even the engine was developed with outside help! seriously, fischer has a better plan. more 600ss roll around than anything else. as a new unknown company why would you even TRY to compete in the 1000+ class? this is a recipe for fail

at least motoczysz has their own engine :rolleyes:

bwahahahahaha awesome!
The only thing you can't recreate from the roehr is the priceless amount of smugness and superiority...oh wait you have drinks and lap dances you still win.

I'd like to see what this thing can do in real life. That 60-degree watercooled V-twin is a heavy unit (200-lbs +) and now add a supercharger on top of that? I'd like to see what the actual bike would weigh in at. Not to mention that they'd have to do some serious modding to the engine because that Revolution engine is a very slow revver. Powerful, yes, but revs slow as hell. When we do roll-ons on the freeway, my KTM is up and gone and my homey's Street Rod could never catch up even though it puts out 20 more horses. You rev the throttle on that Revolution engine and you'll wait for a couple of seconds before anything kicks in. So, I'd like to see what Roeher did to solve that problem.

Well the obvious solution would be to lighten the crank/pistons. Not to mention the super charger which should get things spinning alot faster. They claim a 425 dry weight and they say "modeled" after the hd lump so they might have a cnc/lightened version of the engine. They had to save weight somewhere considering my bike weighs about that.

As far as the price goes,it's not THAT much more than the MV,Bimota or Ducati specials we've all seen and it's still cheaper than most of the choppers riding around. I read an article about this guy almost 2 years ago,he just about hand made everything on the prototype himself.

Why Polaris won't make a sportbike has always been beyond me. Harley tried it and failed. We probably wouldn't buy it even if one of the American Companies did produce a sportbike.... I'm still hoping Buell will do something now that they've broken with HD engines! They're definitely heading in the right direction.

Which is exactly why Erik Buell never did anything with it.

The price doesn't bother me if the quality and the performance are there. It's not any more expensive than a special edition Duck or MV. BUT I really like to see how he overcame the weight issue. Unless that V-Rod engine is totally remade with aluminum, magnesium, and titanium, he's not gonna be able to shed that much weight. The BMW HP2 Sport has a 1200-cc aircooled boxer twin engine (no water pump, no radiator, no water jacket) with the most exotic parts BMW ever made for that engine, coupled with a lightweight trellis frame and a carbon fiber subframe, lightweight PVM wheels, etc., yet it still cracks in at low 400-lbs. Or the KTM RC8 with the 1200-cc (okay, 1150) watercooled V-twin weighing in at around low 400-lbs too.

So, in order to overcome that heavy ass Revolution engine's weight, Roeher must have done some wicked shits. I'm sorry but I'm skeptical until I see some real data and engine/frame designs.

[TATER]

maybe Ford or GM will decide to try to "Revive" their companiers by going the sportbike way..........

it was in CW ahile ago talking about the red test prototype and i think the frame is pretty much nonexistant, it uses the motor as the main stress member on the bike

[smileyman]

Bottom line is I would buy an MV, Ducati 1098R long before i would buy a H-D powered anchor!

[ceo012384]

They did a nice job of copying the MV Augusta's looks.
