Featured here is a 1974 works CZ400. The bike was found by the current owner in
Ohio around 1995.  After purchasing the bike, he set out to restore it.  Most of the
bike was in good shape however the original pipe was cut up and basically
unusable.  It was restored by a friend who thought it was going to be a show
unusable.  It was restored by a friend who thought it was going to be a show
piece.  Per the owner, it was way over done and not period correct...gold painted
magnesium cases, wheels, fork tubes etc.

Shortly after the original restoration, the owner striped the bike down and set it up
to race. The shock angel was returned to period correct 1974 .The owner raced the
bike for several seasons in local vintage events.  Having ridden both production
CZ's and now a works CZ, the owner said they very different bikes on a race track.
 The works CZ handles and corners noticeably better than a production CZ and
produces significantly more horsepower.

The bike is currently going through it's third restoration which will return it to it's
old glory, red frame, aluminum coffin tank etc.  Once the restoration is complete,
the owner has agreed to allow those photos to be published as well.    
1974 Works CZ400
This is the completed bike after the first restoration. The frame was painted blue to match Paul Friedrich's  1972 works
CZ. This bike when found had the Marzocchi front forks.
The bike originally came with a works peanut tank shown below however, it was later fitted with the CZ RV400 model
aluminum fuel tank. The pipe had to be made as the original one was hacked up beyond use.
This is the same bike in race trip.  The shock mounts were moved back to the original 1974 configuration.  Preston
Petty fenders were used on the front and rear.  The owner raced this bike successfully for several seasons.  As he
said, "these bikes were built to be raced, so I raced it!"
Race trim package!  It doesn't get any better than that!!
Sand cast magnesium cases, aluminum air box, works modified foot pegs, Mikuni carburetor.
