WK clean up its act

Sharing the same engine as the 650TR, the WK Bikes 650i is a more conventional naked bike, effectively a brand new alternative to a second-hand Kawasaki ER-6n. And it too is getting changed soon. New patents show a much cleaner design than the current one, with a smaller, slanted headlight and a neat, stubby seat unit. The tubular steel frame is carried over, but the engine cases and exhaust are modified – probably hinting at changes to conform to new Euro 4 emissions rules.
