Is there anyone who has ridden a motorcycle on Talimena Scenic Rd. who can tell me the difficulty of the ride?

I am very nervous about making this ride....I've been riding for a couple of years but not that much and not on any roads like this one...all the information I find talks about twists and turns and dips and hills and I'm afraid I'll hinder our group or just not have the skills for the ride...If anyone has ridden it, I'd like to know - riding the speed limit - is it that difficult? Thanks.
