Its in USD, convert to CAD at 1USD = 1.10CAD
Example with 2004 ZX6R:
Base Price $7,999 $2,735 $3,600
Options: (change)
Exhaust-High Performance (Street) $104 $137
TOTAL PRICE: $7,999 $2,839 $3,737
CAD TOTAL: $8799 $3123 $4111
So ye, on Kijiji it goes for around $3500 to $4500, depending on condition, average worked out to $4111
Those prices are still low. Even after taking currency into account, bikes are worth less in the US market than they are here (which is why people bother with importing them)
