Due to the high cost of cush drives from Yamaha for the RZ350 ($120), A few guys asked me to have some made up. These also fit the FJ600, FZ600 and Maxim. These are $34.95 for the complete set.
Note these are for the RZ350 only, not the RD350 or LC350

We also had Samco make up some hose kits in a natural look rubber finish, still silicone but look more like the originals with a matte finish, no printed logos on the natural ones.
