Normally bikes are chain-driven. Piaggo believes in belt drive
and BMW believes in shaft drive.
Shaft drive the theory is the same as major four wheelers and
above. Shaft driven bikes will tend to be not that fast when pickup
and have a vulnerability of breaking. A replacement will be around
1k plus. I tried that FP dragstar the other day. The foot brake's
location seems to be too far for me. Difficult to brake in
emergency. But still i like dragstar. Dragstar the newer ones are
classic edition.
There are some more choppers like Honda Shadow Slasher, Honda
NV400.
