looking at torque numbers in the Nm unit, for example 51Nm, it tells me this engine is more like a ~500cc mill
then, look at the peak torque rpm, will give an idea if it's commuter friendly or not
then, the hp, and peak rpm to see how wide the powerband is, do i need to drop gear everytime, or just pulas and go
Data - rpm at 6th gear at 110kph
QJ 80hp @ 11,000rpm, 51Nm @ 10,500rpm - ???
Modenas 51hp @ 15,500rpm, 22.9Nm @ 14,500rpm - 10300 rpm (~77% torque on standby)
Honda 93.8hp @ 12,000rpm, 64Nm @ 8,500rpm - 5300 rpm (~88% torque on standby)
Suzuki 73hp @ 8,500rpm, 64Nm @ 6,800rpm - 5100 rpm (~87% torque on standby)
Modenas 650 67hp @ 8,000rpm, 64Nm @ 6,700rpm - 5150 rpm (~86% torque on standby)

You really have to look at the powerband to see how useful it is on the street.

For example this is the powerband for a commuter friendly kawazaki 650 twin. Notice the very flat blue torque curve that comes on strong from 3500rpm to 7500rpm making it a very very responsive in town and you don't need to be downshifting everytime to go anywhere. Can't find the Dyno charts of the SRK but it's going to be peaky .

Maybe can reference the torque curve of the older TNT600. Kind of a very odd torque curve with a dip where you need it the most.
Dont think I will enjoy that sort of power delivery on a commute
Unless you die die want a 4 cyc sportbike, the current crop of twins are far more suited to street and commuting work.
