Only a gear head could tell from the pic, noting the exhaust and handlebars etc. To the non-motorcycle enthusiast there all the same, just some go by them with the wheel in the air and the others make a lot of noise

I posted another pic without the red blanket and upright from an ESPN article.
Interesting to note this about the Pennsylvania law:
Pennsylvania's Helmet Law(Effective Sept. 4, 2003)
Pennsylvania's 35-year-old law requiring helmets to be worn was amended in 2003 to make helmets optional under certain circumstances.
According to the amended law, a motorcyclist will no longer be required to wear a helmet if the rider is:
• A person 21 years of age or older who has been licensed to operate a motorcycle for not less than two full calendar years.
• A person 21 years of age or older who has completed a motorcycle rider safety course approved by the department or the Motorcycle Safety Foundation.
• A passenger 21 years of age or older if the motorcycle driver meets one of the qualifications for not wearing a helmet.
