What Is The Best Gearing For A 2019 Husky Fe 450s

Hi,

Can't seem to find any post on gearing. I just brought a 2019 Husky FE 450s that i will be riding on the street for about 39 miles to trail head. But i do very techincal trail riding. If any one knows what would be the best gearing for techincal trail riding, but would also be ok on the street. All the roads that i will be taking is speed limit 45 miles per hours. Thanks for any help.
