You know, I rode one of those when I had my ZX10r in for its first "free service" - could not believe the low-end (usable) torque it put out, I was really surprised! It would kill a modern sports bike up to 60 MPH......!! Hope you have a good run with it; you will, it's a Kawasaki!
Thanks Rod, looking forward to picking it up
This article explains how they accomplished widening the powerband.....
"The Versys's 650 cc liquid cooled, four-stroke parallel-twin engine has been retuned for more bottom-end and mid-range torque. This is achieved with different camshafts and fuel injection mapping. These changes cause peak torque to occur at a lower engine speed and provide better throttle response in the 3,000 to 6,000 rpm range. In addition a balance tube has been added between the exhaust headers to smooth out power delivery. Power is 59.4 hp (44 kW) @ 8,400 rpm, compared with the Ninja's 65.7 hp (49 kW) @ 8,400 rpm.[1] Torque is 42 lb·ft (57 N·m), compared with the Ninja's 45.5 lb·ft (61.7 N·m)[1] Improving the engine's low and mid range response comes at the expense of a slight reduction in peak power however. A similar approach was recently deployed by Honda with their CBF1000 model. The engine uses a 180 degree crankshaft. This in turn requires an uneven firing interval (180 degrees, 540 degrees) which gives the engine note a distinctive "throbbing" sound at idle."My biggest complaint is with the saddle, with my 6' frame I tend to slide towards the tank and crush the jewels, and not so sure it would be comfortable for longer rides as it feels quite firm.
