Default Technical Information Required

Hello, I am trying to register an imported 2005 Harley Fat Boy 1550 in Scotland .
They want to know engine maximum output in BHP PS kW.
The other question is Maximum power engine speed (rpm) I do not have
any idea what this means.
Finally maximum road speed.
Any help would be appreciated.
Thanks exhausted

Put a call in to HD but you're prolly safe with the following:

60 BHP = 60.8BS or 44.7KW
Max RPM on a stock bike is 5500 (By rev limiter)
Max Road Speed 156 KPH

A 1550 is a 95 cubic inch engine. It's difficult to know what the actual HP is without knowing other components like cams or head modifications. With that being said,my 95" engine had 80 HP so using various online converters :
80 HP = 78.9 bhp
80 HP = 58.84 kw
80 HP = 80 metric horsepower (equals the German Pferdestärke (PS) )

Go with what Jim said for max rpm and kph.

Just wanted to point out the wording on the RPM seems to indicate they want to know the RPM at max power output of the motor;

"Maximum power engine speed (rpm)"

Not sure why that would be, but it is commonly information provided from a Dyno printout. Anyway, that's how it reads to me.
