2010 Roehr 1250sc First Ride









It is a outstanding engineering job just to get that big motor into a sportbike frame much less make it fast. Outsourcing brakes and supension is necessary if you want your bike to have the best components and all the manufactures do it. If every bike manufacture had to build 100% of the parts in house there would be about 1 still in business (even Ural and Enfield outsource parts). Congratulations for getting the prototype built and it shows the dedication Mr.Roehr for spending the fortune it cost to build such a machine.
I like the style and look of this bike. But he sourced the wrong engine. Designers need to stop making decision from the top of the 'Made In America' soap box. Brembo and Ohlins aren't american made so why would he care that the engine is (which technically I challenge because it was engineered elsewhere). He should have sourced Ducati's 1098 or 1198 engine or better yet Aprilia's new v4. So he sourced the wrong engine and then needed to add complexity in the way of super charger to it to get into the same performance league as his competitors. Just stupid.
Let's not forget the Erik Buell has made successful, innovative street bikes and, while Harley now owns a controlling interest in Buell, Erik Buell was one guy working in a barn making motorcycles. In a 2006 interview, Erik Buell had this to say about the V-Rod engine: “It’s too big! It actually was our engine. We started the project and then Harley got engaged and said that we’d like to use it too. And then they said, well actually we’ll probably gonna use it first. And then they thought about it and what bike they could build around this engine. They came up with this big touring cruiser. The engine as we had conceived it was too small. It was wrong. And they said that we want, like in all our bikes, the engine to be a showcase in the middle. In a 66inch wheel-based bike this little engine would just look stupid, so they made it bigger. I said, you know, it’s no longer a sporting engine. It’s a big twin, and a beautiful engine for that kind of bike. But, for me again, sport means nimble, athletic, light and it just became a big beautiful touring cruising engine. I just had to go; you know my customers won’t be satisfied with it. And it’s heavier than the air-cooled, significantly heavier without the water and radiator. I had a target of 140 pounds and it’s (V-rod engine) 210. Nothing wrong with it, it’s just not for our bike.” All that said, I hope that Roehr succeeds and that the bike makes people happy. The vast majority of riders on Japanese liter bikes, Ducati 1198s, etc. would be faster, smoother, better street riders with engines that were less peaky, in frames with ergonomics designed for 70mph average speeds instead of 130mph average speeds, and with suspension tuned for the street rather than for ultra-smooth race tracks. So the fact that the Roehr is not a joy on the race track does not necessarily mean that it's a bad choice on the street.
