79 hp

From our home page:

"The torque power output for the Versys is 64bhp at 8000rpm. Peak torque is 61 at 6800 rpm. "

Let me see now. 61x6800/5250=79

I just picked up 15hp and didn't have to do a thing!

Is this mixing up shaft horsepower with rear-wheel horsepower?

Peak torque is 61 Nm (45 ftlbf) at 6800 rpm. (55.6 HP @ 6800 rpm)

Maximum horsepower is 64 at 8400 rpm.

Ft-lbs multiplied by RPM, divided by 5252 = HP

(64X5252)/8400 = 40 ft/lbs torque at 8400 rpm.

Ya, if only the 79hp was real. My point was there is an error on our home page and we need to correct it, this being the main source of Versys information. I'm quite surprised it went this long without being noticed.

Yeah, those are some nice round numbers. Can I get that with a slip-on?

Peak numbers might make you want a bike, but they won't make you like a bike. It's the delivery that counts.

Like Dry Weight, Peak Numbers are not applicable to the way most folks ride. The F800ST puts out about 85 HP (crank?) at 8000 rpm, but this is not the happy place for that motor. The vibes start at 5k and just get worse from there. The motor redlines at 8500 rpm.

Contrast that with the Versys, although our HP Peak is a lot lower, it's also a lot more accessible in that the motor is smooth and happy up there, and you still have a lot of headroom to hang on to a gear if you want to.
