I wouldn't doubt if you're able to cruise at 55mph with the right gearing. The limiting factor will be the actual space available for the countershaft sprocket. IOW, if you had the space and an 18 tooth would fit (and is available), it might be worth a try.
You're probably gonna need a new, longer chain.
