FZ1 and FZS wheel bearings & Seals:

[b1k3rdude]

So as I needed some wheels bearing for the FZ1 I thought I would check if any of the spare bearings I still have for my FZS would fit, and some of them do -

• FZ1 - fowlers - https://www.fowlersparts.co.uk/parts/639...rear-wheel
  
• FZS - fowlers - https://www.fowlersparts.co.uk/parts/418...rear-wheel
  

Front wheel: (FZS part numbers same)

• 2x bearing (ball)- 93306-00420
  
• 2x seal - 93106-28043
  

Sprocket carrier: (FZS part numbers same)

• 1x bearing (ball)- 93306-20531
  
• 1x seal - 93106-40013
  

Rear Wheel (FZ1):

• 1x R/H bearing (ball) - 93306-20531 - bearing number 62-28-2-RS
  
• 1x R/H seal - 93106-40013 - seal number 40-58-7
  
• 1x L/H bearing (roller) - 93317-33590 -  bearing number 35-20-2-RS
  

Rear Wheel (FZS):

• 1x R/H bearing (ball) - FZS - 93306-07806 - bearing number 62-28-2-RS (so same as FZ1)
  
• 1x R/H seal - 93106-35042 - seal number 35-52-8
  
• 1x L/H bearing (roller) - 93317-43580 - bearing number  35-20-2 RS (so same as FZ1)
  

So the only part that different between both bikes is the R/H (exhaust side) seal, so this means the R/H wheel spacer has different ID/OD between the two bike's.

I personally prefer to source all my bearings/seals from Marksman Industrial, as you can put in the Yamaha (or Suzuki, Honda etc) and it will find your bearing/seal for you. They also have 'bearing kits' for both bikes, which can save you a chunk of change compared to going oem or even wemoto -

thanks a lot for this information.

Your welcome. I did this because I had some bearings and seals sitting in my cupboard for my previous FZS, so I needed to know what parts were shared between the two bikes if any.
