crankshaft horsepower is roughly equal to output horsepower through a gear/chain/belt reduction, but crankshaft torque gets multiplied by the gear ratio. Your engine is making like 1-2 lb-ft at 3000 rpms, the human is making like 20 ft-lbs at 60 rpms... when the gears turn the 3000 rpms into a manageable speed, you are looking at much more torque to the rear wheel. When that engine is tuned to make 4 ft-lb at 9000 rpms, you're talking some serious torque by the time you get to the rear wheel.

but its not about torque, its about impulse, with a direct drivetrain the shock from the engine is run right through the chains, gears, deraleurs and such, which is what really shreds 'em fast.

and there is no briggs and stratton engine that makes 60 ft-lb of torque (on the low end of passenger car 4-bangers)

seriously stop saying stupid shit, and making stuff up.
