Bodywork
Allegedly the upper/lower from a Honda RS250, say from
Sharskinz or Siebemoto(sp?), fits nicely onto
a CB-1 with some minor dremeling for the CB-1's case covers. Also the Ymaha FZR600
race tail appears to be an easy fit. See

A '93 CBR900RR fairing set, with a trimmed CBR600F2 race tail supposedly works too. See

Brakes Chain
O-ring or non o-ring doesn't make that much difference. Non o-ring chains
require more lube and energy to keep in good shape. Chains will last a few
seasons if properly maintained.
