Hey all! How much more effort is required to withstand the wind when riding without a shield on the bike? Is it tiresome? How much buffeting is there at city and highway speeds? Does the wind create extra noise around the helmet? What are the advantages/disadvantages of a shield, if any? I've got my eye on the Yamaha Virago 250 cruiser and it doesn't have a shield. I think I'll be riding alot on the highway at high speed, will a shield improve comfort? Cheers! Buck
