I found the cheapest spot for tires is at Parker Bros. in Toronto www.powersports.ca
and if your looking for cosmetics you should check out www.mototeck.com
out of Montreal they have some nice stuff for the gixxers. I had my tires picked up by someone who was in Toronto for a weekend so I don't know what shipping is like. But I've shopped around and found they were the cheapest for most stuff, I got a good deal on my RF800 Shoei there too.
