Hi!

Definitely No. The number is Clutch Horse Power.

What they do is: 

1. Accelerate the rear wheel and calculate the horse power there by
the acceleration

2. Pull the clutch and calculate the horse power the drive chain and
gearbox take by the decelleration

3. The clutch-hp is the sum of both.

This way is a pretty precise way (+-5%) to measure.

So take it that the AT has nominal 60hp. Engines vary by +-3%, so this
one might have been a 62hp. A measurement variation of +5%, you have
65hp on a stock AT.
