[QUOTE="Digital, post: 10727624, member: 66214"] For a good driver in a cobra you'll need about as much hp as they have CCs for a newer bike. That said you will chase down most of these bikes on the high end. A lot of people think they beat a 600 because they passed it at 130mph. That wasn't the case, he just ran outa gear. 1000s will not go faster then 170-180mph GPS'd. They start to slow down around 160. So if you're geared for top end you'll run them down eventually. We'll do some quick math just for perspective. We'll use the 2011 CBR1000 since it pulls nasty outa the hole and has great mid range, but still a 180mph gps'd top end. So the bike weighs 439 pounds with a full tank of gas and all. Lets say I'm on it. I can tuck with the best of them, i'm 6'1 and weigh 160#s after a 3 course meal with all my gear on. So that's 600#s. The bike usually dynos with minor bolt ons 170rwhp. Now for the cobra. We'll be "fair" and say most cobras weigh 3800 and we have an actual human that eats so 200#s for the driver. 4k. You make 650rwhp which is a good number for most TS or eaton sprayed cobras. By the numbers you'll need 1100hp to beat me. Now obviously other things come into play with all that. It's much harder to drive a bike to its full potential then it is a car and such. But that's by the number. Also because a car has more surface area it has to defeat a lot more wind which comes into play the faster you go. We'll have a more "fair" setup now. Let's try the CBR600 2011 model. With a fat dude on the bike. The bike weighs 410lbs. Plus lets say 240# rider. So we'll get 650#s. It makes 100hp with some bolt ons. So even with a fat rider you'll need 600rwhp to beat this bike. Again this strictly by the numbers. If I was on that bike you'd need 700rwhp. All that being said driving a bike to it's full potential is not only difficult but can be very intimidating and VERY few riders can bring their bike to its limit. You'll see a lot of riders not tucking, not clutchless upshifting, missing shifts, shifting too early, or too late, and usually starting in the wrong gear. This results in many kill stories that were just bad riders being beaten and not the bike. In car racing that doesn't seem like a good excuse. But lets say you had flat tires, started in the wrong gear, and bounced it off the rev limiter, then lost to a much slower car, would those be a good excuses? I'd say so. If you're not in a eaton cobra with spray or a TS cobra you did not beat a 600. You either out ran them or you beat a shitty rider. And I can promise you didn't beat a 1000. You beat the fat dude who was 2 gears down sitting up eating wind who was scared to wheelie so he was at 3/4 throttle. [/QUOTE]
