I am the ownner of a 919 ´o4. I live on the west coast of BC (Canada) where it rains a lot. I´m looking at extending my riding season by two months (one in the Fall, one in Spring). In order to do this I believe I need to have better suited tires (the stock ones are good on dry pavement but otherwise...). Any suggestions out there as what would be the better choice? Where I live, price and availability are also factors. Thanks
