I had 2nd thoughts when I traded the fz6r in as well.
The moment I gave the 09 some throttle , I was in love.
Test ride the r3 and see if its for you or not. That's your best bet
Have them and love them. Really lets you adjust to your leg length.
I bought mine before they added the option to add the passenger foot pegs so I went with the ankle guards instead.
You're not reading it wrong. That chart is not the best conversion scale.
I wear a 10.5 in everything. If I went by their chart, I would be looking into getting a 45.
The 43 fits me perfect everywhere except my wide toe area. The 44 I tried on when I originally purchased the boots was too...
