Really impressive. What other mode are on the motor? Any better picks of the SC installed. I can't really see much in the current pic.

Sweet number sheet. You shift it at about 5300 you better be hangin' on.....regardless of the gear....Good stuff bro.

That is an incredible torque curve.

Maximum acceleration will be achieved by shifting it at 5950 RPM, regardless of what gear it is in.

Wow. What's the torque at 2500rpm? I can't see the vertical axis numbers.

I can't see them either , but extrapolating from what I can see I would surmise about 145. Impressive. Even more impressive is the "curve". It is a constant incline and never stops until the rev limiter is hit.

"Never cross the steams Ray, You'll create alpha particles".... "But Mama, that's where the FUN IS!" Culminated max "power" and Torque where the streams cross at ~ 5300....That's where the Fun is...! Won a hell of a lot of street races that way......... ;-)

Ride safe.

Maximum power, and the hardest acceleration, on any motor is always at peak torque, no matter what the RPM is.

You are correct in that on many large V-Twin engines that are built with a 6000 RPM limit, the "most fun" does come in by reving past "5300". That is by coincidence. On a Japanese crotch rocket, the "most fun" may come at 10,000 RPM. That is because of it's torque curve too, which might peak at 9500 RPM.

On this thing, it never stops increasing the pull all the way to the limiter at 5950 RPM. Peak power is at 5950 RPM. It would likely continue on up if the limiter were raised. Very impressive.

The horsepower curve, and the "5300" that you talk about, is simply the mathematical calculation using the SAE formula for horsepower, and really means very little when it comes to how hard the bike, any bike (or car) accelerates. (Actually, the number is 5252). I generally ignore the horsepower curve. It is simply a math calculation and not a power measurement. It means almost nothing. All you need to know about how the motor is performing is in the torque curve. In this particular case, the torque incline.

Yeah, I know, everybody is impressed by the "horsepower" numbers because they are usually the bigger number. That's good marketing. James Watt figured that angle out a long time ago, when he came up with the mathematical formula when he was trying to sell his steam engines to miners and farmers who were using horses for power. They wanted to know "how many horses will it replace". After measuring the work that mine ponies could do in an hour, rounding off some numbers for easy figuring, then estimating how much more a draft horse could do than a pony, and rounding off some more numbers, he came up with the "horsepower" formula we all use here in the USA today. It is popular because you get big numbers when you rev past the formula's constant of 5252. That may, or may not, be the point of most power. When it is, it's purely coincidental. On some motors, like crotch rockets, it may be over 9000 RPM. On others, like a semi-truck engine, it will be closer to 1600 RPM. In both cases, they will pull the hardest at peak torque.

I rev my Victory to 6000 too. Lol!
