It is becoming clear to me that the introduction of the Fazer 8 was not a huge success story in the UK - mostly I guess down to the price.  Just try and get hold of a set of stomp grips in the UK and you will find it impossible and be directed to a "universal" fit requiring you to "cut to size".  The American Yamaha "blurb" says they are the same as '06~'11 FZ1.  Maybe the American FZ1 but not the British! Trust me they are NOT.

The trouble is trying to find these in the UK.  The link on the web site sends you to Yamaha US.  If you search on e-bay for instance they look nothing like these!  I contacted my local Yamaha dealer (where I bought the bike) and they knew less than me.
 
So I googled the part number   ABA-0SS56-21-79  and had partial success but all the web sites are in the US.  The recommended retail price from Yamaha is $48.95.  The first seller I found wanted circa $150 postage!
 
Anyway, I plugged away amd found these guys:

They sell them for $41.26 and the postage to UK is $15.95 making a total of $57.21.  Could get sucked into an import duty hike I suppose but worth it to get a set of properly fitting tank AND side grips.
 
I have ordered today - will update you all when they arrive.
