Rear Shock Absorbers for Yamaha RD250/350/400 with 14mm bushes
will fit all 250/350/400 RD's from 1973 to 1979, all chrome with 14mm bush kit included.
they have a black internal sleave potecting the damper rod ( can be removed by disassembling the shock, removing the top eye)
I have been using these for the last 5 years and found them to be very good.
