The best choice for the front would be the Avon Cobra Chrome Trike tire AV-91 but it is a bit pricey and seems to be out of stock at most places. But if you find one, make sure it's a "TRIKE" and not just the regular Cobra Chrome.I got lucky and got in on a rollback at Walmart last year and it only cost me $85. That will be getting installed sometime in the next couple months as my front is worn down.
A great substitute which I have been using for last several years is the Michelin Pilot Activ tire. It is a rear tire but gets mounted on your front rim. I found it at a decent price here and they have stores that will mount the tire for you:
Michelin Pilot Activ Tire | 38% ($84.68) Off! - RevZilla
Or just buy and take front wheel to your favorite motorcycle shop.
