I think it is very individual. Especially when you get into competitive fields where folks are usually self-selected. I've got a female friend who holds 2 or is it now 3 Bonnieville Salt Flat records. She also enjoys wrenching and has won awards for her hand built bike, the one she set one of her records on. I had a sister in law who rightfully wore the t-shirt "if you can read this the bitch just passed your ass." Competitive doesn't begin to describe her though she has mellowed as she's gotten older. Then there were the women racers from the 30s and beyond: Dot Robinson, Theresa Wallach, Margaret Wilson (logged over 550,000 miles during her lifetime). But then this isn't about racing and notable women adventurers from recent years are Sherri Wilkins who rode around the world solo. Danielle Murdoch who rode 45,000 miles from Australia to Africa. 17 year old Natasha Moss who rode through 15 counties to raise money for charity. Cathy Birchall who rode in 31 countries - solo. While these are more extreme examples the number of men who have done the same sort of riding is also limited. Women on motorcycles doing adventure riding isn't new with ladies like the Van Buren sisters were among the first of either gender to ride coast to coast, traveling aboard an Indian Power Plus in 1916. Their achievements included summiting Pikes Peak. Not to mention Bessie Springfield who rode cross country solo on her Harley in 1930 and continued to do so 7 more times. BTW, she was a black woman her cross country trips included the deep south. There are some issues that maybe unique to women in terms of safety when traveling solo but frankly they are probably somewhat less than those of any woman traveling alone. FWIW, this is an excerpt from a rant I posted on another forum when someone was denigrating a bike as "a girl's bike" as if women were inherently less capable of riding.
