WOW, the TT version is a rare bird. Nice!!!
Many people don't know that the W1 series was Kawasaki's 1st bike (copy of the BSA A10).
They used to make just motors and their biggest customer was Meguro, when Kawi decided to get into motorcycles, they bought out Meguro and just rebadged the W1, plus a couple tweeks, but nothing major.
Uber cool!!! 8)
