Sure, if you can afford to replace the rear every 1500 miles. Looks like the front will go to 3500 and most all of the miles are on backroads and some quite twisty "goat paths" which are common on the Central Coast.would you buy / recommend them again?
As a track day or an agressive street tire, yes, they are great. The BT-090 is Bridgestone's lightweight bike tire. A step up would be a BT-002 Type 4 (Super Soft) front and a BT-090 rear (or it's replacement) for the track. If you want more mileage, I'd look elsewhere.would you buy / recommend them again?
