Yes dunlop d402 and d404 both come in 130/90/16. That is the stock size for the 650.
130=Millimeters in width from sidewall to sidewall
90% =Ratio of height to cross-section
16 =Rim size
So with this 130 millimeter wide 117 millimeters tall
farmalldanzil, many thanks for your quick reply! I'm brand new to this forum & I'm still figuring out how to use stuff. I live in Guilford CT. I'm a 63 year old re-entry rider who stopped riding 19 years ago due to my career (musician with insured hands). Looking forward to more correspondence with good folks like you! Ride Safe, West
