are becoming increasingly difficult to obtain and expensive at around
£20.00 or more for a set of 2 i.e. one seat lock plus one steering lock
with 2 interchangeable keys.
are 2 basic types of lock and the only real difference is the length of the
rectangular piece above the barrel. Club spares has supplies of the lock
with the long rectangular piece only £5.00 including postage BUT with only
locks are often similar to the lock pictured with a key inserted. If you are
unable to get a seat lock it is possible to easily modify both “basic”
extension piece on the seat lock is a piece of tube 1.5 cm long, 1.2 cm in
diameter and with an internal diameter of 0.8cm. One end is filed out
slightly to make a tight fit onto the brass barrel. It is either glued in
place or better still drilled and pegged with the peg being filed off flush
with the extension tube. If the photos reproduce well you can just see that
JAWA have used the peg method.
surplus rectangular section can again be hack sawed away and then filed down
to reduce it from 2.2 cm to 1.6cm. So there we have another money saver and
nobody will know how clever you were.
your seat must be secure for an MOT pass. JAWA CZ locks are not very strong
and soft enough to drill out so always secure your bike with the best chain you can afford.
